What's the best brand of high flow cat?

Yeah sorry forgot to mention, those instructions only work on track cars

Think i'm going to give a magna-flow a shot it'll get installed on Tuesday along with new front-pipes & cat-back that arrived during the week

XFORCE is the way to go for balance between performance and reasonable pricing, at the end of the day if u are looking for performance u need a full 3inch system, shop around, ul be surprised how much the price may vary, usually depending if they've done custom twin turbo down pipes before, most guys couldnt be bothered doing it so they just make up a ridiculous price that no one would seriously pay

AVOID these types of XFORCE cat convertors at all costs

they're a pile of shit. one blew out on me after about 10thousand k's and covered the inside of my exhaust in ceramic crap.

cheers xforce....bunch of d!cks

Just to let everyone know, I know it's illegal but the best cat for cars with big mods that use an after market ecu is a pipped out cat. I've seen plenty of well know brand name cats melt when excess fuel is sucked through the exhaust.

exhaust dump cutout pre cat? sounds like a winner

 

[king_panther]

would that be in screamer pipe territory Paul?

Eh, just bash out the cat & wack a bit of striaght pipe through it to maintain the illusion. I've blown 2 to peices so far.

If cops figured it out, it would be worse then screamer pipe. Would probably be the best flowing exhaust possible though

 

[unclepaulie]

i think the side pipe hangin out under the drivers door might be a give away haha

I had a metal cat on my last car. Definitely high quality design and construction. Their website has technical data regarding flow etc I think it would be hard to go wrong with one of these. The bottleneck would be shifted to other areas of the exhaust system anyway...
