are there after market Y pipes out there that work (bolt up) to stock headers/man? Im looking to just get rid of my cats, but if i pull it off to "hollow" them out id just rather but a new y-pipe. any sites? thanks!

 

I remember there was a company called Stainless Works that made stock replacement y-pipes out of stainless steel of course and they had the option of having no cats. Frankly though, for the little gain that is involved by doing this, I would just save the money or just chop out the cats and weld in straight pipes. Otherwise, just worry about an aftermarket y-pipe if you ever do headers.

 

I bought Y-pipe from SLP online a few years ago for $79.00 for stock exhaust manifolds.... It was a discontinued item for my '93Z.. Mandrel bent tubes and 1/4 bigger than stock....

Not sure if that what your looking for, but if it is, you might check them out..

 

does that stainless works come with O2 sensor bungs? or do i have to get the bypass's...
