i was wondering is it worth the money to get a highflow cat. I am getting the custom enterprise y pipe and am wondering if i should get the high flow cat as well. The cat on my car is perfectly fine now. Would the high flow cat give me any hp increase ? What would it do ? Would it make my car worse ? My whole exhaust system is brand new oem replacement parts. The only thing i am definatly changing is the y pipe. And the high flow cat if it proves that it will actually do anything with my setup. Please let me know, thanks for your help!

i would not get one unless you acually needed to replace yours
i am about to buy one soon, cause i need to replace mine.

 

I AGREE.....cats DO NOT hurt performance like they used to in the 80s and early 90s........they flow pretty well now

 

At least for our cars they do.
Eliminating the precats in the OEM y pipe is what helps our flow.

 

well the reason i ask is because custommaxima is having a group deal for a high flow cat + a y pipe for 350$ . i was just wondering if its worth getting the hi flo cat.

 

Only if you're boosted is a high flow cat worthwhile.

 

no cat is the best cat... 1.2 hp

 

Ya only good if your cat is bad or you got boosted and want mad power other wise get a faster car

 

Ya don't bother, def not worth it...unless you boost

 

yea i wouldnt get one not unless u neeed to replace it. i need to replace mine. its the only thing on my piping that i havent upgrade. oh that and headers!!

 

I had to get a Cat! So I went with Budget.

 

only if u need to replace yours or ur boosted like stated above

 

i got the package deal mine has had the bees in the can noise let me know how your y-pipe fits mainly in the front pipe

 

Which brand did you buy? What year car?

 

not worth it. wont be able to tell the difference

 

i replaced the cat only because everything was rusted and to install my new y-pipe i had to.

i didnt use a hi flow cat because the dyno tests are not that great and i want to pass emissions... while the one from CE might pass emissions, im rather to be safe than sorry, and atm i think that price they list is kinda expensive. 175$ (mabe 150$ i forget) i think it was... plus the 299$ for the y-pipe.

i bought the ypipe with the group deal, good price, 213$ with shipping and install kit.

 

not for the 1 or 2hp i also think it is a waste

 

if you run a test pipe, what do you have to do to keep CEL from turning on?
