I'm now ready to upgrade my 04 USP unitronic stage 1+. I want to install AWE FMIC, ecode testpipe and an exhaust on which my choice isnt clear yet...
So, do you think guy, these mods will make my car more pleasant to drive and do you have a exhaust to suggest to me, I dont want a loud car and I heard bad things about APR, where I was interested in the stealth model...
