I'm planning on buying and installing headers and y-pipe on my 01 ss. I was wondering if mix matching is okay when it comes to all the parts. I want to go with BBK headers and the y-pipe. Will the y-pipe fit to my lm1 catback? Also, i cannot seem to find any cats besides the SLP highflows. Does anyone know of any cheaper ones that will work?
Thanks.

 

maybe that's okay. but it's up to you.
