I have a 2000 GMC Sierra with the 5.3L vortec. My local exhaust shop said there was no way to put true dual exhaust on it because the gas tank was in the way Is this true? or is there some other way to set it up?? please help!

It can be done, but he's right, both pipes will have to run down the passenger side for a long way.

Thats what I thought when I looked around some. Where would be the best place to put the mufflers with a setup like that?

I have mine in the same position the original was. A big Magnaflow dual in dual out. Some do 2 smaller dual mufflers.

I ran mine out of the headers straight back over the trans crossmember passenger side into cat, drivers side into cat then crossover at about 45 degree angle to meet passenger side then into x pipe then into two xr-1 mufflers dumped over the axle.

Yeah, with a 2wd you can get over the crossmember and head over to the passenger side after that. With a 4wd (unless you are Trever1t) you need to crossover at the transmission.

Thanks everybody. I think im going to have high flow cats installed then a 2 in 2 out muffler of some sort. What do you recomend that adds alot of horses and still sounds mean?

I have 3" true duals with custom X-over after the cats into 2 individual Magnaflow's (not sure which model, but they're big...I had them lying around from the OEM replacement catback I did)...drivers side goes over rr axle and around the spare to have both exit out the back...see my photobucket for a sound clip and a few pix...not really happy with the rear exit and lookin to make a change. I'm playin with the idea of old style side pipes under the rockers...

Thats a very nice looking truck! Thats basically what im planning on doing but I have found a model of flowmaster that has 2 in and 2 out ports for about $115 and I can get the local shop to run the pipe fairly cheap.
