if you got a 6.0L youll be alright...

[RoLL1n D4rK]

yeah 3" no 5.3L

[S/C Z71]

2.5" max.

[RoLL1n D4rK]

y 2.5?

y 2.5?

3" it to big for a 5.3. if you were running single exhaust, 3" would be fine, but for duals don't go any more than 2.5" with 3" you will most of the scavaging in you exhaust, and alot of low end power. with a smaller pipe, your exhaust will scavenge better and have a higher velocity, and you will get better power out of 2.5" than you will 3"

What he said.

wtf does that mean???


i already have 2 3/4" i just want that ****er louder

You need to retain your back pressure. If you want it loud, do 2 1/4" into your 4" tip. It will be pretty loud and will off echo off everything.

you have 2 3/4 duals? only exhaust i have heard of bein 2 3/4 is stock.

but 3" wont neccessarily be louder, but it will be deeper in tone.

[RoLL1n D4rK]

would it **** anything up if i run 3"?

Only your bottom end. Unless you're planning on forced induction and a lot bigger engine do not do 3" duals. Best setup would be either a single 3" or dual 2.25" if you're doing a true dual. Also, if you're doing duals put in a crossover like either an x or h-pipe to balance the pulses between the two banks. Also I hope you're planning on some mufflers too since with straight pipes it'll sound like assshole.

[RoLL1n D4rK]

straights sound amazing i dunno what ur talking about.... so i wouldnt blow up any thing by running 3"?

[tom ward]

straight pipes sound like as$

[RoLL1n D4rK]

i had true dual 40 series flows and that sounded like ass so i cut them bitches out and welded some pipe in that my friend sounds awesome then add some high flow cats **** is ****ing amazing!!

[LoudBigBlue]

yes, straights sound good, and dont put an h or x pipe in it, the crackling part is the best
im completely serious!

[RoLL1n D4rK]

i was just wondering what it would sound like. i had no plans on doing it

Yes; because sounding like a 40 year old log truck with a misfire is a great sound. Going to a true dual exhaust doesn't require a crossover, no; but it does add some power back to something that would be way overkill for a stock engine. Unless of course you just want an obnoxiously loud truck that sounds horrible and makes you look like a dumb**** 18 year old high school kid.....oh wait, nevermind.
