9-3 Sedan, Cabrio '04+, Combi, 9-3X Workshop
Hey guys, I'm sequoia, I'm nw around here and looking for some advice.
I picked up my new 9-3 about a month ago and it's time for some upgrades. My plan is to do some intercooler upgrades and a full turbo back 3 inch exhaust, but I don't want that annoying teenage ricer fart can sound. Any one...
