Ok first off, please done bitch at me for not searching. Im not feeling very good right now and I really dont feel like searching.

I am just curious to know what all of the Stock Exhaust tubbing sizes are. ( Header, DP, Catback)

I want to get a full exhaust. Soomething with a 2.5 catback. If i got the 2.5 catback should i have a 2.5 downpipe and header? Bigger, Smaller?

Whats the best size set up?

Thanks alot in advance!

 

There's a huge debate over this...

so you plan on doing a full header, dp, and exhaust?

If you wanna do that... I'd go with a 2.5" cat-back with a 2.5" downpipe and a decent header of whatever brand you like...

an exhaust is only gonna be as good as its smallest part...

 

If you want a 2.5 CB go 2.5 DP as well and a good header. As for the stock sizes it varys between 2-2.25-2.5"

 

alright thanks alot exactly what i needed
