Where to get cat bypass pipes?

Anyone know where I can find Cat bypass pipes for my 2.5L that will bolt up to the stock system? IE these pipes need to have a triangle flange to mate the headers, and straight pipe to mate the mufflers.

Such pipes would also mate up to most aftermarket systems as well (such as Che's).

Can't find any on ebay... And I am definitely not spending 900$ for some when my ebay headers only cost 50.

Someone should make these, I'm sure they could make a few quick bucks. Not sure why Chinese aren't already making them.

He's right. The 2.5 variant only has one set of cats. Therefore, if you remove them, you'll be catless . This will certainly trigger cel's, and the only way around it, would be to re-map the ecu.

I was under the impression that you can run the sensors open air. You will still get the CEL but it will not run like crap... either way just get a ROW flash, delete the secondary air system and Viola! magic, cat-less with no CEL and no secondary air bullcrap.

or have it remapped like johnny said with some other aftermarket software.

CELs for emissions don't really matter much.

Also, it is ludicrous to charge 500$ for 3 feet of pipe with incredibly simplistic bends and only one flange. I would never buy them from fabspeed. The actual value of the fabspeed pipes is about 50 dollars, including labor if they are mass produced in China.

I have said the same thing. waste of dough-flow.

it seems to me that if the boxster likes some back pressure then maybe, having some pressure bent 2" pipe wouldnt be that bad. you would lose weight have some back pressure and have some great sounding exhaust. and its cheap.


but i could be looking at this simplistically.

I agree. And for $50 they should throw in a Chinese massage as well. Unfortunately, there are very few choices out there - Fab$peed, $chnell and maybe $tebro .
