Does anybody know where (online) to buy high flow catalytic converters with 2.25" inlet AND 2.25" outlet? I've tried ebay and they have 2.25" inlet and 2.50" outlet cats. I'd like to go 2.25" piping all the way through for my B16.

if only they have bolt on cats...not weld.

 

Talk to someone at Magnaflow. Their Carsound cats are the best value for your money.

 

why dont you just gut u'r stock cat?...that'll be really high flow

 

Kteller can weld flanges and o2 bungs on a cat for you. I also think Catco makes bolt up cats.

Actually that's been proven to restrict flow causing a loss in power because you now have an open chamber that slows the exhaust and causes turbulence. A high flow cat has the same amount of air restriction as a 90 degree mandrel bend, in other words it's not significant and wont even show up on a dyno. Super Street even claimed to have gained some torque switching from a gutted cat to a high flow.

He probably doesn't want his car to smell and sound like an old lawnmower. Unless he's from Tijuana and he's used to the way cars smell down there.
