i here some have problems with the y pipe hitting the bottom of the car, i dont wantthis to happen because it may cause false knock, how can i stop this? and i hear the car will run rich with longtubes, is there anyone i can send my pcm to to just get it adjusted for the headers that isnt insanely expensive, again sorry for being a pain, i just dont wanna buy something anymore like i did with my v6 w/o fully researching

 

no appology needed.

as for tuning...i think you're limited to places like www.pcmforless.com , madwolf, or tbyrne and the like.

don't know about the clearance probllem with longtubes (will know soon). but when i installed my bassani ORP on my manifolds the pipe hit the frame (brace under driver floorboard) when i would launch or when i would really punch it in 1st or 2nd gear....whenever the engine would really twist under torque.

i cured it by installing poly motor mounts...now the motor hardly moves when reved and the pipe doesn't come close to the frame.

i have pics of the spot on my webpage in the sig...page 2

 

I have LT's and a 3" y and my pipe hits the bottom of the car when ever I get on it, you can do polly motor mounts. Ive tried to get some kind of mount put on from an exhaust place but its gonna cost a lot because its so far from any place to put a flexing polly or rubber mount. But it can be done- its just a custom job

 

My Jet-Hot Y-pipe didn't hit the floor, but if I left it in gear during deceleration it would rub. When I sold it it had one little rub spot on it. You could always put radiator hose between the pipe and the frame. Cheesy but effective.

 

Mine also hit. I installed a Prothane motor mount on the drivers side to fix the problem.

 

I installed a Prothane motor mount on the drivers side at the same time that I was installing the headers and never had a hitting problem.

chris at jethot told me the newer ones wont hit because they redesigned them asgain

 

we just put jet hot longtubes my friend 02 ls1, install was easy, but a primary touched the k-member on the driver's side, he has a custom y pipe that doesnt bang at all with stock motor mounts....
