I found this one, but it says no muffler.. I dont know if it comes with a straight pipe replacement or not

check out performance truck products. they offer a full 4" turbo back kit from diamond eye for $229 with free shipping. cheapest around. thats straight pipe as well. muffler adds $30

I dont like the way diamond eye exits. That was going to be the route, but the exit is what I dont like. I like the MBRP/FloPro exit.. at a slant.

 

[webb06]

right on. PTP is the cheapest place ive found for exhausts though
