exhaust help

[Amphilophus]

I am sure this has been asked before but i couldnt find all the answers I was looking for. first what is the stock pipe size into the cat? and were would I find the pipe that goes after the cat and before the catback? thanks.

stock pipe is 2.25"

You need an LT1 take off exhaust to make it fit the best, LS1 is NOT an direct bolt in. These are 2.75"

Magnaflow makes the most complete kit, comes with a new S-pipe thats 3" if you buy the LT1 kit. You will pay around 400 dollars for the kit though.

into the cat it is 3" and out it is 2.25". the best way to get the pipe is to go to summit and buy a u bent pipe and cut it in half and turn it to make an s and weld it back. alot cheaper than buying it from like SLP ;)
