I was going to try it but 3 muffler shops said it could not be done on mine because of the clearamces over the axle and out the rear. I also have a 20 gal gas tank on it. Instead I decided to run a single 3 inch out the rear. I like it alot I used a flowmaster muffler sounds great.

Anyone ever consider running the exhaust in the rear wheel tubs instead of under the body floor? Seems like there'd be plenty of room. Just a thought.

I'd do a single 3", but if you really want duals you may look at doing side exits right in front of the back wheels.

Be a real man and go out through the hood. At least you don't have to worry about back pressure sucking in water.

It would only be legal if you have a hard top cause the windows have to be glass for it to be legal, but you can do it with out a top if you want.
