4 inch exhaust
 
I was just curious what a 4 inch exhaust would do for me... Its a 3.5 inch v-band outta the turbo.

helps a good bit. I just did mine a week or so ago, huge improvement going from old set up(3.5 dp to 3" mandrel and a magnaflow race round 14 " muffler) to the current( 3.5 dp to 4" stainless mandrel bent with a 32" diesel muffler).

Is it shorter the muffler the louder?

Yes. You can here mine in the link below. It was a 300 dollar cheapo straight through. I am going to add another short muffler after the axle to tone it down some. It is a bit loud for my taste.

Can I see your picture of muffler if you have one?
