Celica Forums General Discussion Exterior high flow cat ?

I have a TSRM and I was considering putting a high Flow Cat on, and then Removeing the Resenator. Could anyone give me some feedback on this?

I have TSRM W/ Resenator removed($25.) It sound twice as loud I love it

that ain't save though, for the environment i mean..hehhe..but who really care right??

i was told that the celica already had a high flow cat

Yep, the Celica's cat is already pretty high flow. Just get the resonator removed.

exactly

what part of the exhuast is the resonator?

the piece right after the cat. a muffler can also be considered a resonator, because it slows down the air.

a high flow cat will maybe give you 1 hp...

so you will only gain in Top end right ? it won't af fect your midrange?

Don't replace your cat. You'll only cause yourself problems, and you may even lose power. High flow cats are for larger displacement engines, and they cause major headaches with OBDII systems (read: any vehicle newer than 1996) such as incorrect O2 sensor readings, poor fuel economy, improper fuel mixture, constant CELs, plug fouling, EGR problems, etc.

Large displacement, and cars with big Turbos. Taking the cat off of a an NA car is useless.

get a test pipe

dumb question- whats a test pipe?

if i'm right , a Test pipe is just like the Kazuma
