Lawrence, my 360 passed emmissions without the cats... but, we don't have the rolling dyno test down here so that could be it. Passed with flying colors though! Ernesto | ||

Actually, I have heard/been told that late model Ferrari's will pass emissions testing without catalyst. | ||

Of course Ernesto, that is understandable as even as a retailer I too am a customer of other things and shopping around is a common thing to do. By the way how is the weather down there? | ||

Yes, shipping was about $200.00 from the UK. Total cost was a little more than $1,000 less (including shipping). I have no problem with supply/demand market forces at work, in fact I respect the relationship. BUT, I like to shop around and not overpay for things. No biggie. Ernesto | ||

Ernesto, I was going by what Tubi has for suggested retail and I'm sure it would always be less priced out of country just like anything else not made here. There is a high demand on these mufflers so the U.S. Dist. could sell for whatever they can get for it, nothing wrong with that as it's business like anything else. FYI the Tubi muffler for the 360 is less than the $1000 you quoted but of course how many dealers are dumb enough to sell it at such a low cost when there is a demand. I haven't called around for the going cost for Tubi's as I could care less, I sell them as long as I could make a reasonable profit for my time and hey it's not much in labor to make a phone call. Also shipping from Europe on a Tubi? how much could that be? I've had merchandise shipped to me from Asia and it's not cheap and I could imagine a Tubi being at least a couple hundred for it's weight and box size so your actual cost is up from the cost of the muffler. | ||

A couple hundred? Try $1,000 less. Well, i bought mine in europe. Can the price difference be that big? Ernesto | ||

Suggested retail for a 360 tubi is $3500. According to my dealer cost it can be bought hundreds less if you look around for example you could've asked me but too late for that, hey, I mentioned it to anyone who was looking for a tubi system a while back but oh well what's a few hundred bucks anyway right? chump change for F owners? | ||

Gary, the answer is volume. Ernesto PS. $3,700 for a 360M Tubi?! Sounds like a little too much for me... | ||

So, can any of you Tubi dealers tell me why the Tubi Corvette system (pictured down a few posts) with that stainless steel and TWO silencers sells for only $1,350 but my 308 Tubi (single muffler) lists for $2,300??? What's up with that?? Why the $1,000 difference in prices??? Gary | ||

i really appreciate all of the help with this matter. with the spider there is a low end hum/resonace that is very loud, i'm just going to sit on it for a while and see if it chills out. because of the weather in chicago, i've only put maybe 50 miles on the tubi, i hope to change that asap. | ||

Nick, Sarcasm aside, those two Tubi guys start with a flat SS sheet. I'll leave the rest to your imagination. (use the attachment for help). There are ways to make things cheaply and quickly; Tubi has always resisted the temptation of compromising quality . They could have easily used ready-made chromed tips instead. Manu is absolutely right, Tubis do take a while to "settle". We've observed that on many applications. I also know of at least one 02 360 owner in CA who had his CElights come on after removing his cats.  | ||

Nick, I bought the Tubi for my 348 from Manu. Followed the thread and have to say that his statement about it seems to be right. When first installed I also noticed a boomy sound when just idleing the engine. Especially at traffic lights in downtown traffic there was some annoying low frequency sound which could get on your nerves after a while. The grumble totally disappeared when reving the engine. Now after putting around 300km on with the Tubi (and Tubi Test Pipes and K&N air filters) the low grumble when idleing seems to be gone. It�s still a low frequency but nothing like before when the sound was so low that it actually seemed to reach you stomach... Propose you wait some more miles before changing such a perfect product... Con saluti cordialissimi, Jens Haller | ||

2 guys, 2 days to make exaust tips? Hmmm.... Sounds like Tubi better invest in some high-tech machinery. Or does one of those guys actually go out and mine the steel, melt it and then hand pound it into a flat piece of steel to begin forming the exuast tips? Tubi wouldn't be trying to make some simple exaust tips sound like rocket science, would they???? Gotta justify that price somehow. hehe........ | ||

I got my '01 Tubi Spyder with 4.2K miles already on it, and there is nothing regarding the engine/exhaust note that I would consider to be boomy. If possible, maybe take it over to a mechanic who has run into tubi cars before and ask him for a quick listen? To my ears, it just sounds like a lower decibel Indy car. -- John | ||

very interesting, the tubi is new to me and i did not know that they "settle". I guess i'll just sit on it for a while and let it do it's thing. how many miles does it take for the baffling to do it's thing? | ||
| Manu (Manu)
Member Username: Manu Post Number: 670 Registered: 2-2002 |
Allow me to but in. First thing - Noel - how long have you had the Tubi - you need to know the following - it takes quite a lot of mileage for the baffling inside the muffler to compress to it's final position and relase the true 'note.' A new Tubi 360 sounds NOTHING LIKE a Tubi with some proper mileage on it - like anything of high quality it takes running in. Any kind of boominess you are getting is going to settle down A LOT - and a lot of the bass will turn to a sensational howling noise... awesome. This is a VERY special product - I strongly suggest you let it 'settle.' I also suspect that the product may be incorrectly fitted and there may be a 'leak' causing the boominess you are talking about (which I have NEVER come across). Second thing - de-catting any Ferrari up to the Bosch Motronic 7.3 system does NOT result in warning lights. PERIOD. Very few of you realise that cats are cleaning the very last x% of emissions - on 348s and 355s they are effectively useless and cause WAYYY more problems than they 'solve.' Check the cats that come off your cars one of these days - they're probably hollow with totally fried 02 sensors. Tino will know more about US regulations but I know what has happened in the UK. | ||

what Frank said was that the smaller diameter tips of the stock exhaust will produce a different pitch(stands to reason), than the larger diameter tubi tips, therefore less low frequency rumble....aka resonance. | ||

Yes, removal of the cats will cause the sound to increase at least 2X. Ernesto | ||

I'm told that the angle of the Lambda sensors to the airflow is critical. Also, if you're concerned that the car is too loud, why remove the cats? | ||
| Tino (Bboxer)
Junior Member Username: Bboxer Post Number: 244 Registered: 8-2001 |
Let me chime in here if I may. As a 360/Tubi owner and a Tubi dealer (MENSI), I have some info to share. I talk to Franc almost on a daily basis and never heard him or Lou say that stock tips will make things quieter. here's another fact: A couple of weeks ago during a conversation with the owner of Tubi in Italy regarding another application, he told me in no uncertain terms that Tubi tips are silencers by themselves (look at the perforated inside liner, more "silencing" material is behind that.), so if aything, I would think that a Tubi muffler with stock pipes would resonate. Besides, it takes two men two days to make the beautiful Tubi tips from flat sheet, why would you want to replace them with the cheap (yes cheap) stock tips. On the subject of emission equipment, It is a fact that a change occurred in 00 with the addition of precats but I 'm not aware of emission equipment changes after 00. Anybody ? | ||

Intermediate Member Username: T88power Post Number: 1323 Registered: 2-2001 |
My car is 2000. I had the stock tips on the Tubi muffler for a while (the Tubi tips cracked and I had to have them fixed). I noticed no significant drop in sound levels, but I can't really remember. Regarding the cats/ECU issue, I suggest you do you research, like EFWUN said. I took a big risk in doing it. I bought the Tubi bypass pipes and installed them. Installed the factory O2 sensors on the precat brackets and dud ones on the aft cat brackets. I believe however my car in an anomaly as it only had one O2 sensor per side, and I was expecting two per side. Ernesto | ||

Noel, my post was well-intentioned. I'd suggest asking Franc; he is well-informed. Lots of people say they took off the cats "no prob"; nevertheless, I've done lots of research on this, and if you don't mount the Lambda sensors correctly, you're gonna have big trouble. Simply removing the cats will screw up the ECU, and throw double check engine lights immediately. | ||

Ernesto, what year is your car? mine is an 01 and I'm wondering if the OBD is different? also, has anyone put stock tips on a tubi? | ||
| Ernesto (T88power)
Intermediate Member Username: T88power Post Number: 1322 Registered: 2-2001 |
Never seen them. I was expecting the Check Engine lights, so I had purchased the O2 simulators. Turns out I never needed them. Ernesto | ||

Removing the cats will not screw up the way the 360 runs. I removed them on mine and it works perfectly. A lot more high-rpm power. Ernesto | ||
| EFWUN (Efwun)
Junior Member Username: Efwun Post Number: 118 Registered: 2-2003 |
Noel, it'll goof up more than your emissions. The ECU relies on signals from O2 sensors, and removing the cats will screw up the way the car runs. With OBD II cars like your 360, there really isn't anyway to get around that short of major surgery. Franc says, (and I trust him almost implicitly) that the cats are very low restriction, and there's also the bypass cat that cuts in on hard throttle above 4K'ish revs. | ||

yes the cats are in place, the car is stock except for the tubi. if i remove the cats will that goof up my emissions?...i'm sure it varies from state to state. | ||

I talked to Frank at tubi in michigan(very helpful, nice)about the loudness of my tubi.<<<this>>> Frank suggested that i leave on the tubi but put the smaller stock tips on the exhaust, therefore leaving the high end screem but lowering the low end grumble/resonance. i'll give this a shot when the weather in chicago gets above freezing(in august)  |
