Alright, I've sat back and read posts for a few weeks now, and I've got my exhaust planned out... now I'd like some opinions on the setup I'm thinking of:

SLP 1 5/8" Headers

3" In/Out Catco Cat

3" Intermediate Pipe

3" In/2 1/2" Out Flowmaster Muffler

3" Tips

I have an intake, and mods that are in store over the next year are a cam and chip. Does this sound like a good setup? What would you change if anything? The only parts I'm definitely set on are the header brand (SLP) and muffler brand (Flowmaster). Lemme know if you think I should change a pipe size. Thanks in advance everyone

Nope, I wouldnt change a thing, unless you were planning on upgrading to a stroker motor in the future. If so, I'd move up on the size of the primaries.

As is, I'm going to end up selling my exhaust after only two seasons becuase I'm stepping up to a minirammed 385 for next year and will need a bigger exhaust.

Thanks for the lightning-quick reply, WS6 It's great to have you guys to bounce ideas off of Anyone else?

 

get a catback to avoid high muffler shop costs.

true taz. a shop I really trust is doing my buddy's headers next week for 200, and we've gotten exhausts there before, so I am still going to have everything installed by them. Any more opinions?

 

Sounds like a tried and true thirdgen exhaust system if I've ever seen one.

 

Thanks Jza, three thirdgen owners' approval is enough for me . Looks like I'll have an exhaust by the end of the month
