Cool Exhaust question

Hey guys
Is there really a differce between 4" and 5" turbobacked exhaust even with the manifold only being 3 1/2"? If so is it worth the price difference? Also I want the deepest loudest exhaust possiable. Any suggestions, thanks

Smile exhaust

I had 4 inch turbo back MBRP fitted but then had to refit the original downpipe adapted to the rest of the 4 inch. more power, acceleration and just a nice rumble noise. Cops down here jump on noisy trucks lol

No performance gains with 5", the only real reason people buy the 5" is because it gives the exhaust a deeper tone which helps get rid of a little of the hair drier turbo sounds and also for looks. Other than that, no differences.

Ditto.....Unless, you plan on making big power. Then a 5" is of some help.

well if the 5" gives a deeper sound I think I have my answer. Been looking at flow pro 5" exhaust w/ no muffler, anyone suggest bungs or no bungs, what are they?

No bungs if your running h&s or spartan.

4" is all you really need, but 5" does look and sound great on these trucks. You do not need the bungs if you are using an H&S or Spartan tuner. Check our site for more info and pricing on exhaust kits, let us know if we can help with anything.

go 5" with a muffler..... turbo back if you think you will never have to swap back to stock, otherwise go down pipe back as i don't thing the minor gains is worth the hassle... the muffler will help even out the exhaust note......for IMO a better sound...

that's my next question should I go turbo back or downpipe back... is there a difference with sound and performance? Im going with a spartan tune so no bungs is turbo back more of a hassel to install?

what are the bungs for? i thought you needed to get a pipe with the bungs so that you could still use the stock sensors?
