Ls1 Cat eliminater pipe
LS1 stock headers and dyno tuned.
Slp Y with loudmonth, Flowmaster muffer and several other set ups in the back.
Want to remove cats and run pipes direct into SLP Y. In other words, stock headers direct to Y pipe.
Does anyone know if TEST PIPES, or cat eliminater pipes are avauilable from a supplier? I remember years ago JC Whitteny sold Test pipes for this purpose.
they did not fit right at all, and were non-stainless. I'd
be looking for a testimonial on something like that.
It ain't rocket science, but some people fail at "wheel".
