You can change it in stages, downpipe, cat, catback etc. The stock catback is pretty good, decating or fitting a sports cat is best for gains.
Which tailpipe did you choose Soulja? Sounds like the dsci would be perfect for me. I want something a bit throatier without waking the neighbors up when I'm on nights!
Very nice, and very good mods too.
Wish I got the B8 dampers put on mine!
Got mine done few weeks ago, great improvement.
They are genuine. The owner posts on stoc. He also offers some good deals in the discounts are from time to time.
