4" exhaust install done, opinions inside
#1
It turned out way better than what I was expecting.
The stock exhaust was cut right after the y-pipe and a 3" to 4" reducer was used to go to 4". Then the 4" magnaflow race muffler was welded on. Then the muffler shop bought a 4" mandrel bent tail pipe for a short bed duramax. The tail pipe fit up to the muffler and all hangers with zero cutting. The fit and finish is top notch. The 4" tail pipe actually comes out at the same spot as the stock pipe so you have to look real hard to actually notice its bigger. Very sleeper.
I was worried about it sounding rednecky, however it does not at all. Nice rumble at idle and sounds bad **** at wot. Droning is also very minimal.
Should have pics soon.

Sounds cool. I've been thinking about building a custom Y-pipe from my AS&M headers (once they're installed) to do a dual 3" into single 4", then from there back use the Summit Racing 4" mandrel bent piping that they make for the diesel extended cab trucks.







We need pics
