Catalytic converter length..?

[Mr.Smith]

Anybody have a JSM downpipe and RPM's 3" exhaust that can tell me what length of cat i need? Just ordered the exhaust and would like to order the cat now too. For a Syclone.

I would ditch it unless you need it for emissions

Factory cat = 19 3/4" from flange to end.

I've already been done this road and just pulled everything off to come up with a different solution. I had the exact same setup you have. The issue was that the JSM downpipe ends in the factory location. Apparently most 3" high flow CAT's are shorter than factory so you end up a couple inches short. Not impossible to fix, but my entire exhaust is stainless steel so I didn't want to just build some kind of adapter as a fix.

My advice is to bolt it all up and measure where you're at.

Test pipe = 15" from flange to end.

It"s a 3" in/out high flow and stainless. Its the same cat that RPM sells. I bought it as a replacement for my PTE downpipe and ATR catback exhaust. Brand new in a box, $150 shipped. Not sure if it will work with a JSM down pipe though? I'll gladly take some measurements for you.
