Kelly, I am not sure if you can post one here, but there is a site hosting an exhaust contest referred to in another thread. You could post it there and put a link here. Jim

Kelly, your mufflers are much higher than mine, which is also a Tubi but they are located right behind the bumper. Makes everything blacked out since nothing really behind the grill. (I too like the wheels...and wouldn't go back to stock). Hmmm, how else can we improve our TR's??

I still have the black wire mesh (honeycomb) behind the slotted grill. The polished stainless Tubi just shines right through like it's not even there. You can actually see a little of the mesh reflecting off of the Tubi in a few places. That picture was taken after two days of driving in the rain so the car is very filthy.

I love those chrome wheels you have on your TR Jim. I wish I could use 5 lug wheels. I think my next purchase will be new Speedline wheels similiar to the 288 GTO wheels.

Kelly, did you take out the honeycomb grillwork behind the slotted grill? Or does it just not show up on this pic? Also, my tips look diff so there must be some variation...

My original muffler looked like a rusted out bucket of bolts and on the TR you can see the muffler extremely well. It actually looked a lot like the pre cats on the picture that HenryK posted of his exhaust system. Looks account for a lot. Expecially on a Ferrari. Now I have nice looks an great sounds. It's definitely worth the $$$ spent.

Anthony,
I very big on the look's of of the tip's, I love the look of the 360 (Tubi tips), Any choice on tip's, or do you get what you get with the Tubi?? Also my friend got a new updated Tubi for his 360, sound's GREAT..sound's better than the old style,I wonder if they make the "new and improved model for the Testarossa"?? I need to start looking into it!!! Any pictures of your car you can post??

Robert I have a tubi on my 87 tr. They are a different shape to those pictured on the 512 as in this thread they are oval in shape similar to a standard shape muffler and they sound great at anything over 3000 rpm and once over 4000 sounds like an f1 with balls. Thoroughly recommend the expense. At our recent nationals many participants came up and said how great the car sounded when we were doing the motorkhana.

Henryk, I have a 512TR , I replaced the cats with Tubi pipes, but instead of fitting the Tubi muffler, I had the stock muffler 'gutted'! We then replaced all the baffles etc, with two perforated straight pipes, on starting up I was very supprised how quiet it was!! it sounds awesome above 4k revs ,but at idle very similar to standard. Those Tubi people must be very clever..........

Bruce and TR owners:
Assuming that your cats are restrictive (and they may not be depending on wear/silencer etc) - hollowing them out may reduce backpressure a little and allow the car to breathe easier. Having said that, these cats will still be "muffling" the car a little - reason being the enlarged diameter of the cat (over say a test pipe) will act a sort resonation chamber to calm the sound down.

Aside from destroying cats by hollowing them, fitting test pipes leads to a more aggressive sound because of the above.

You'll often find that "silenced test pipes" look exactly like cats from the outside (also contain a bit of baffling on the inside).

YOU DONT NEED TEST PIPES IF YOUR CATS ARE HOLLOWED OUT

Kelly: If your cats are hollowed out, then there is no need for test pipes.

I put test pipes in my TR, because the cats are good......didn't want to hollow them out. When I sell the car, then the cats go with it, and the new owner can put them back in, if he so desires.

I think I need to remove my airpump now. Thanks for the info guys. One more question. Test pipes. What is the purpose of test pipes if you have hollowed out cats? I am under the impression that test pipes can be used in place of functional cats. But, if you have hollowed out cats I am not sure what test pipes will do for you. Am I missing something?

Does it make sense to remove the air pump for the Catalytic Converter if the cats are hollowed out? I would think that it consumes some energy from the engine since it is belt driven. And, I'm not sure it adds any functionality now.

MY CATS ARE PUNCHED AND HOLLOWED OUT- HONEYCOMB GONE

MY PUMP IS GONE, MAKES MORE ROOM, AND LIGHTENS UP THE CAR...FAN BLOWER DOES NOTHING

Kelly: I am in the middle of my TR major service, and just removed the whole air injection system. I see no use for it. With it removed there now becomes a lot more room to get at more important things that may break.

JIm: Regarding back pressure and burnt valves; Think about it.....it is HEAT that burns the valves.....the quicker you eliminate the heat, the better. Show me a dragster with mufflers!!!!! The heat thing is strictly for emmisions.....to burn off more gases......at the expense of the valves. A tuned exhaust is where the header pipes are of equal length, as they are in a Ferrari.

Kelly: I agree.

I had a Tubi installed today. My cats are hollow. The sound is much better than stock but it could stand to be a lot louder and still not be as loud as some of these Diesel Dodge Ram pickup trucks that I pull up to at red lights. Those things are very loud and they are stock. What is the difference in having hollowed out cats and test pipes?

Hank, Jeff, don't you think there are any advantages to a properly tuned exhaust? When I have my Tubi pipes off, I see the headers have some baffling that is twisted like rifling. Don't you think changing pipes will effect performance, perhaps adversely? I have always heard that inadequate back pressure can result in burned valves. Is that not a concern?

Jeff: When I had the Tubis off.....just open behind the pre-cats, I started the car......it was NOT as loud as I thought it would be.

If the sound is too loud, then I will just splice in a set of small resonators.

I still think we can then work on putting a small trunk in the back....ala 308.....hahaha......!!!!

Whatever I do to my car, I can make up for yours...I have all the welding gear (TIG, MIG), and even my own exhaust pipe bending/flaring machine.

Greg: I don't know what you mean by "regular Tubi". I bought this new from the dealer.....they are original. The exhaust tips come with the Tubi. They look just like the original....that is, twin polished tips on each side.

Robert: FYI, the test pipes are aluminized steel, and NOT stainless......to keep the price down. I feel these should last a long time.

Make me an offer on the Tubis.......they are in excellent condition, with about 15k miles on them.

Robert: I tried that route. There are no "stock" flanges available by the muffler places, that will match the Ferrari flange, in either OD or ID. The Ferrari flanges are also tapered, on the ID, to accept the tapered pipe properly. I had to machine the flanges on a CNC mill, and use a lathe to taper the ID. Only then will it fit snug up against the stock donut gasket.

I sold a pair to someone for $275.....no complaints. This includes a welded bung to accept the O2 sensor.

I will try the no muffler route.....if I don't like it, then will re-install the tubis. I should be done in a few weeks.

Henryk,
I was going to pull off the cat's and take it to a shop I use, and have them match up a set for me. What is the price for your set??

So no mufflers at all..Hmmmm..something to kick around..So when will your Tr be running?? Nice to get feed back from you on the sound!!..Robert

Robert: The Tubis are still heavy, better sound than original, but still not quite loud enough (at least on the TR).....that is why you see TRs with no mufflers at all.

It does drop out as you see it.

Where will you order straight pipes from, and how much? I am making another set for a TR......interested?

Hello Henryk,
So your saying Tubi is not quite what it is cracked up to be?? I just need some kick in the sound, way to tame!!! So you drop the whole unit out in one piece?? I also was going to have test pipes made, again thank's for any imput you might have!!..Robert

Robert: Here is a picture of the Tubi, with straight pipes. I used the pre-cats which are gutted. I am doing a major service on my TR, so I have it out of the car. I am not sure of what Bruce is referring to, regarding the mounting brackets, because my Tubi uses the original brackets on the car. The sound is nice, but only after 4K RPM. When I install the exhaust back into the car, I will try a straight exhaust going out of the pre-cats, with no Tubi. I made the straight pipes, that you see, myself.
