Exhaust Crossover Pipe?

[grandprixgtp_91]

Just wondering, when i make my exhaust crossover pipe and down pipe, what kind of pipig should i use? can i just go to the local auto parts store and use the exhaust pipe they have on the shelf? or do i need alot thicker piping? if so does anybody have any specs? also i know i want to use 2.5" piping for my downpipe because i dont think i will have room for 3". but what size should i use for the exhaust crossover?

thanks!

I used thick wall (alot of weight and heat, don't use think wall shyt from parts store.) 2.25" for the X-Over and 2.5" for the downpipe. I used aluminized but when i redo it im going to use stainless. Jegs is a great place for stainless piping.
