On my 2002 GMC 3500 I'm wantin to put 4" exhasut on it but I've also thot about duals which would sound and look better. 4" pipe all the way with just 5" single tip or dual 4" with chrome tips. Also wonderin if anyone has ever been around a dmax with a triple dog downloader on it.

 

Dual vs single is your call. I have duals because I like the look and it's symmetrical "OCD" and as much as I normally don't like bully dog, my bud has the t-dog on his lbz and it will flat out run and gets good milage on the lower settings.

 

Alright man on your pickup do you have tips on ur exhaust or is it just pipe comin out the back

 

I have 6" stainless tips. Do yourself a favor and get stainless over chrome. They will last and look good for as long as you have the truck

 

Alright man I thank ya
