4" exhaust

[arrowheadracing]

Well I finally got my 4" in place. Was super easy. Didnt have to modify anything. I took sounds of stock, no muffler and muffler. So if your interested check out the website, I ll post the wav files latter tonight. The no muffler was way too loud and vibrated almost everything in the truck. The muffler is still a little loud for my peronal taste when you get on it. But normal driving its good. The turbo definetly spools faster. Alot faster. But with all the noise, its hard to really feel any performance gain, cause the truck now sounds like its moving faster then its going.

Ok sounds are up and the complete installation with many step by step pictures ( I think I have 25 or so ). It wasnt that hard to install at all. I am going to take some more sound files in the next day or two.As the truck got really loud and having the camera there made it really raspy. But its a definete difference between stock loud and no muffler loud. You really be able to tell.
