Thanks

Your stock is most likely 3" in 2.25" out like the rest of us. I went with a Catco 3" in and out, and no SES light so far.

Ill try to keep it the stock sizes.. dont wanna have to buy adapters and stuff..

The 3.4 is 2.5 in to whatever your catback is out. Check my sig, my setup worked really well and I have no SES light but I had to fabricate adapters myself because I was installing it myself. A shop wanted $250 to do the whole job and wouldnt make me adapters so I had to weld it all myself. I think my catco is a 2 way w/ air tube but the tube came capped so I just left it how it was. hope this helps.

Also, goto summit and buy a catco for $60 shipped. IMO all high flow cats are the same. Go with Catco.
