did my exhaust (cat back)

Alpha Trion · 02-02-2012, 04:40 AM

Hey guys,

So finally got some time to have a play at my mates workshop.. We started at the flange after the dumps, took off the 2 cats and went 2 into single 3''

3'' into a mid muffler and then 3'' out the back, no muffler to the tips.

I love the growl, very light drone around 2000rpm but put the foot down and from 3000rpm on it lets people know in a very sexy way that you are around! Acceleration feels a lot more responsive as well.

Very happy with the result and will dyno soon.

I don't follow what you did exactly.

From what I can decipher he did a catless resonated midpipes with a muffler delete.
