im geting my 3" dual x-pipe installed.. lets see when i get it back do video and see if it helped.. Im thinking 10-15rwp
stock pipe is 2"od
I think the 3.7 highflow cats bolt right up but you will have to get a bung fabbed up. On the 3.7 the bung is on the rear of the cat. The 3.0tt has it in front of the second cats.
Thats my next exhaust mod soon,just got done talking it over with my exhaust shop.
Highflow casts $$ plus 150-200 for the install /bung. i was quoted. Thats good for another 10-15rwp
on a N/a you 7-10
However the bolts are very difficult to get to, you can even see them from the top.NOt sure whats the process on removing it.
stillen i think is working a on Intake.but i don't see it its really crammed in there even in front of the radiator there stuff in the way.
then the wait is on for a tune, and maybe better intercoolers,bypass the boost sensor somehow .
should be good for 500-600 for not to much hundos
