aftermarket exhaust with AP.

boone2.5rs · 06-24-2012, 12:42 AM

so i have purchased a 2004 subaru impreza sti! but first i need to fix the leaky oil pan,radiator hose, and crossmember but to the real question now what do you guys "and girls" think of a cobb bellmouth catted downpipe to a 3 inch borla cat-back with a cobb accessport? i just want to know if this will achieve that deep godly subaru boxer sound? i would hope so since its around a $1500+ setup but money is no option when it comes to this car. thanks in advance!

The cat back is what really changes the sound, the downpipe (any aftermarket) is what allows for more power. Do some reading in the 2.5l technical forum as basically every question you could think of has likely been asked.

Downpipe will change the sound.

Searching would have shown this is a good setup.
