Must have been one hell of a muffler to make a performance difference. I can see straight though my muffler, it won't change performance at all. It does take the cab drone out, plus if a Cop crawls under and sees no muffler, it could be a fine. Depends where you live, and the local laws. For the price difference, I wouldn't take the chance.

Idk the laws around here i live in utah. my dads truck has no muffler it has a aero turbine muffler which i bet acts like a muffler reducing cab drone but idk.

If you can weld go for it!! :jump:

I agree

Our trucks are loud as s%*t anyways, i am very please with my 4" w/ muffler. From the outside the straight pipe sounds good, i have never ridden in a vp truck w straight pipe to comment on cab drone. I just know the engine itself is loud enough to turn the radio up a few extra clicks while cruising w/ the muffler system. I know the CRs w/no muffler are very loud inside at cruising rpm.

If your truck is a short bed, the length of pipe left over from the kit with muffler is just about right to where you could run with the muffler and if you dont like it, take the muffler off and stick in the straight piece.
