will 5 inch exhaust hurt the performance of a stock truck? i am getting ready to ditch the stock exhaust. i like the sound of the 5inch but i dont want to lose power. my truck is stock with nothing done to it. my plan is too do exhaust, turn up timing, bigger fuel plate then put a valve body and torque converter in the truck for now. i want to get a good exhaust but i dont want to lose power.

 

4" is plenty of flow......5 is simply the WOW factor.............it wont hurt yer performance at all, a diesel like no backpressure at all

 

I have an 03 but exhaust was the first thing i did (5" straight pipe) and other than not being able to keep my foot off the pedal it didnt really affect much performance wise.

 

What I've gots in my sig. Love it, no it doesn't drone on the highway, and no it doesn't affect low end tourqe, at all. Don't let anyone tell you otherwise

 

Ok then 5" it is. Haha

 

What brand and system are you going to get? I got one from ebay that came with a free 6" tip. Diamond eye, aluminized. Theres one with free shipping and one with $45 shipping. If you go that route, pay the extra $45 and get the free tip, haha.

 

$279 shipped at rollinsmokediesel.com

 

5" turbo back aluminized straight pipe? $279?

 

I lied, $289 but if you use the discount code you get a better price.
