Cat back or turbo back?

[Strokeittothemax]

Is there a big sound difference between the cat-back exhausts and turbo back exhausted?

Depends on how you set it up.

What size? Keeping the cat?

Thinking 4" right now because I heard with 5" the truck gets a little goofy or something...

OK so I am officially a stroker owner as of 3 days ago. Its stock and Im thinking exhaust and cold air intake first. I am also wondering about the pros and cons of cat back or turbo back. Also muffler or straight pipe? Is there a big diff in HP gain or fuel mileage?

[Strokeittothemax]

leave your stock intake, it has the best filtration! exhaust part other guys need to help... hope they can help you and me!

[Newbe]

Hmm ok thanks! Its used but only has 74,000 on it so I just want to take it easy for awhile but thinking the stock exhaust has got to go. Just dont know whats best.

yeah 4" is the way to go the muffler and cat should go bc it will help with the temps and back pressure anything over 4" is a waste of money

also depends on the sound you would like. A cat back will leave the cat in place i believe. A turbo beack system (depending on brand ect.) will delete the cat and you can run a muffler(your choice) if you like. That will get you more grunt from your exhaust

[Newbe]

IM good with aggressive sound. Does the exhaust control the amount of smoke it blows or is that controlled more by a tuner?

[mjschardin]

Not really alittle but def the tuner will do it but with a more aggresive tune will raise your temp so be carsfull watch those temps the smoke is a plus but you dont want to blow the hg's
