okay so If I have a B series swap in an EK hatch with Type R exhaust and the hytech rep. header, what cat should i try and track down? i know there is an optional extension for the header... any help would, help.

 

just get a high-flow cat from summit. its super cheap. its like between 80-90 bucks. catco is another good place. and there are tons of other places. if you're thinking oem, don't bother, they all flow about the same. of course if you guys don't have emissions you could always go catless, but it will be loud as [freak]. just warning you. there would be no point in trying to track down a type r cat. which b series if you don't mind my asking?

 

B16B, i also dont want to have to weld it in, and i had a magnaflow high flow cat that was also loud as hell lol

 

I have a b-series as well and I am using a stock 96 Civic EX cat extended to a stock R header, until I get a better exhaust... then carsound cat. Check out Ebay 75 bucks for a OBD2 cat. GL

 

so what mid pipes are you using? and do you have a hatch or a coupe?

okay every one this is what i want to know: i already have Spoon rear section, and T1R makes mid pipes for 92-00 civics, if i get these and an ex cat, will they bolt up to a 99-00 civic si header, or should i get the long tube header???

 

well try to find a type r cat then

 

just go with no cat straight pipe all the way!
