On the 3" exhaust, I have seen a few people talk about this being a very good setup for supercharged cars like the TTS or probably the AMD setup, not sure on AMD, just a guess. But as with most any exhaust, just slapping it on without a tune to take advantage of it is retarded. I am sure that my JHM setup was not going to put down 360/293 by itself. And the tune alone was not going to put down 360/293 alone. So if the guy who says it felt like a Milltek, just popped it on and expected instant results above and beyond a Milltek, he found out quick thats not the case.
As far as a 3" on an NA car, based on things I have heard from AMD, this car is optimal with a 2.75" for NA. When going up to a 3", you still have the issue that the header pipes are only 2.5" anyways. Also I think there is something to be said about maintaining velocities in the exhaust. With cooling, contraction of exhaust gases, and uniform oversized pipes, this could have something to do with why its not getting as much as say a 2.75" system. Maybe it stalls and causes pressure waves. With a supercharger though, there is alot more air flowing in and exhaust flowing out of the car.
$5-$6k seems high. JHM was not this much, and thats with the x-pipe, the hot swap cats and test pipes.
I have a tentative buyer for my setup. He is in the UK though. Shipping is a bear. I am working with him on it, but we also need to wait for Ben’s setup. Hoping it is here in a couple weeks. Also I told him the shipping costs and he may be second guessing it. Not cheap, and thats cutting it in half right before the mufflers to pack tighter. We will see what happens. i have someone else more local (seattle) interested as well, but we shall see if he is really interested or just talking about it.
Lastly, guys cmon, the time slip thing is getting old. Stop beating on people or dead horses. I am sure swesna ran a good run, we all know 12.75 is possible. I am sure he did something close to that. Disparaging it will not change the fact thats what he claimed, and without a time slip its just a claim, unverified as everyone knows Leave it at that. Its doing nobody any good beating on this every thread. its not like we are awarding trophies or money here. If he said he did high 12’s, and it is possible for a stock car, then I see no reason why he didn’t. Its just not a time of record for “official” tracking.
