these are just general performance mods i'd like to do to my 8, i figured i could ask here. Anyway i just want to know how much better my car would preform with a high airflow air filter in it, with a racingbeat cat back exhaust, aluminum engine pulleys and a MM access port cobb tune?

2007 6speed AT here.

thanks for the reply's and answers.

 

Driver mod is always the first mod.

 

Lmfao

 

turbo is a great mod!

also, short shifter from RP is a necessity

*ok no shortshifter because its an automatic!

 

true but all i really want to know is how well my car will perform with the stuff i am gonna add to it, like a rough estimate of the HP, and along with the stuff i listed probably put a good set of fuel injectors on it too.

 

i started just with clear corners, look where i ended up -_-

Minor differences unless the rpm limit is raised to MT levels. Then one risks the tranny.

 

Buy a manual, then search.

 

lol i just got this car, i wouldnt buy a manual now, but all im lookin for is a little bit better preformance gain, nothing to fancy.

 

You'll likely pick up about 30whp with those mods. If you pick up an Access Port, you'll likely gain about 10 more.
