tino - i'd actually go so far as to say that if you lined up 10 people to listen to both ELEVEN of them would pick the tubi ;-). it is a wonderful sound. when you start her up, just wonderful. conversations stop. it's a gorgeous noise. your info re: quality is interesting data - and now that you mention it, i believe i have heard likewise. that's definitely a factor. my power argument is that a few percent low-end torque you could notice all the time whereas a few percent high-end hp you'll rarely touch. can these things be "quieted"? steve - i do not know the answer to that question. i just drive 'em :-). the unit was on the car when i bought it. clue me in - how can i tell? if it's test pipes that'll be much louder right? but it probably would have a harder time passing emissions here in MA?. johnwto - i have no complaints thus far and a lot of grins. it fits the hole i wanted filled, which was a normally-aspirated torque machine. i wanted a car that kept pulling ewven after you killed the engine ;-). it's the only feature of my departed M5 that i missed. i've only really wound her out a couple times now, the roads around boston have been largely snow-free, but not free of dirt, sand, and salt, and (body rust/damage aside) the traction control definitely dislikes those things. too much power to get any good drives in. she's destined for storage any day now, sadly - the weather forecast appears to be getting downright uncooperative. i can't wait until march when both beasts will be out and i can really do some back-to-back on them. as for the trade, i've heard of a lot more people trading 550s for 360s than the other way around (eg: the prev. owner of my car traded for a 360). i don't know why, but found it curious. 550 values are absolutely in the toilet - it's great if you're a buyer. 360s haven't been as beat up (relatively speaking, as a percentage of MSRP). i bet you could get a stellar deal on a trade setup. doody. | ||

Doody, It's a strange fact but the following is true. Tubi works with Ferrari, mostly in secret. The simple fact is that Ferrari does not believe it should include above-average, highly polished muffler/pipes and Tubi loves it for obvious reasons. I took off my stock 360 muffler myself and it is indeed poor compared to any aftermarket unit, not just Tubi. I have a manufacturing company that heavily relies on welding quality (www.mensilift.com) and I can confirm that the quality of the materials and WELDS on the Tubi is far superior to stock. The guts of the "box" (and the diameter and bends of the piping) account for most of the distinct Tubi sound. it is accompished by the selection of the material as well as the baffles location and thickness. Again stock mufflers are very poor compared to Tubi. Now about the TQ/HP affect, it's mostly academic as a cat-back freer-flowing exhaust (more units of gases per minute at constant RPM) has very little effect both positively and negatively. It reduces torque at lower RPM and increases HP at higher RPM. We conducted same-day/same-car tests on the best candidate, the NSX and others and found out the effect of a CAT-BACK exhaust is barely noticeable. An increase of 2-3% in HP is the best you can expect. (It's a different matter with headers). AFA sound is concerend, we all know it is subjective. But ! I will bet my shirt that if you lign up ten people and have them listen to the same modern Ferrari with stock then Tubi exhaust, the majority would go for the latter. In conclusion, please disregard everything I've said, I'm highly biased <g> To each his own. Happy New Year. | ||

doody -- Are you running "Tubi + test pipes" or "Tubi + cats"? | ||

johnwto - for starters, i don't work for ferrari and have never conversed with the maranello designers. so this is just my educated opinion, fwiw. first off, the fact that the tubi saps some of the power is not optimal. any "enhancement" that reduces power output is suspect. we can probably be certain that they tested dozens of exhaust setups on the maranello during initial design. they would have logically picked the one that best dealt with the outflow mechanically within some reasonable scope of aesthetic acceptability. note that this is not a trivial exhaust system - it has all sorts of variability to it, etc. - it's been engineered, not just slapped on (no knock to the tubi - i'm sure it's great - but it most certainly wasn't a "hey - salvatore! grab an exhaust out of the parts bin for this thing, will ya?" exercise). since there is a power loss, any discussion of aural aesthetics is really moot, but that's what gets discussed anyway :-). secondly, the aural aesthetics. imo, the 550 was designed to be a low-key (relatively speaking) vehicle. it has some serious subtlety to it as ferraris go. the fact that people confuse maranellos with supras and whatnot had to have been (IMO) an identified risk of the design. remember what it replaced: the TR series. the word subtle was never used re: those cars, and that was part of their design goals, undoubtedly. but the 550 clearly wasn't intended to be a loud, brutish thing (which the tubi makes it - and, hey, MANY or even MOST people prefer it - for all that money why not have it scream!?!?!!!). the 550 design is simple, clean, and even elegant. when the testarossa was being designed, things were culuturally different than when the maranello was being designed. at nearing a quarter-mil a pop, the 456 and 550 had to sell into a customer base, most of which probably had some disdain for (or at least little nostalgia for) the culture that the testarossa came out of (or at least how it was generally depicted in television, movies, magazines, etc.) at the time. my opinion. worth precisely no more than what you paid for it ;-) doody. | ||

Bart, Good luck with your visit at Autosalon Singen. If you should search for a good service and the best prices in Europe for Tubi products you should definitely try Manu at Scuderiasystems. I just bought a Tubi for my 348tb and after extensive price comparisons I can assure you that he has the best prices in Germany and most probably in Europe. He is an extremly helpful person. Since he is a FChat member you can contact him here or via www.scuderiasystems.com Con saluti cordialissimi, Jens Haller P.S. If Bart would be in the US I would recommend Tino off course  | ||

doody, could you explain what the original design philosophy on the standard exhaust is? most people that i speak with, including the dealer, think the freeer flowing exhaust is much more suited to engine, especially at higher rpm. thanks | ||

bruce - what's with the yelling again? is an alternate days kind of thing? :-) matt - my 550 has a tubi. at some point in the spring it will probably no longer have a tubi. it's an intoxicating sound, but it's too damn loud and jarring for my tastes (and it robs power). i 100% understand why the "tame" stock 550 exhaust was designed the way it was, and i violently agree with that design philosophy, so my tubi is probably (better than 50/50) coming off. anybody looking for a used (~4K miles) 550 tubi? doody! | ||

I didn't mean to make it sound that it had anything to do with Tubi, the company, or the staff. I just meant that I want to run an honest company and the emails that I have been getting said that I had made some misunderstood statements about my relationship with Tubi. I don't want anyone to think that I try misinform anyone so I decided to not carry Tubi products to releave the situation. Tubi is a great company that builds a great product and in my opinion is the only exhaust system for Ferraris. Sorry again for the misunderstanding. | ||

To do it right for my 360 the back bumper had to be removed. However I have heard the Tubi installed without removal of the bumper. Whatever approach is used it should not take more than two hours. | ||

Due to some emails I have received over the last few days about a misunderstanding of my relationship with Tubi I will no longer be selling their product. I made this decision based on my own morals to do business in a upscale and honest way. Thank you for your support and please check my website for other parts for your vehicle. | ||

I have recently signed up to sell Tubi Style exhaust systems. I have updated the Ferrari and Maserati section with what is available from Tubi. Tubi also makes systems for Audi, Lotus, BMW, Corvette, Acura, and Lamborghini. Check out my website for some of these Tubi systems. www.GodsilPerformanceOnline.com |
