i have a '98 GS w/intake and cat-back apexi N1 exhaust. i wanted to get one of those straight through design cats. but then i read somewhere that not enough back pressure is bad. they said it would actually make you loose power. i will be getting turbo soon, but for now, if i got one of those hi-flo cats would that hurt anything? will i loose or gain performance? thanx.

 

somebody has to know this....

 

you would have a nice lil gain. i noticed it through out the entire rpm band. it wont hurt your engine at all.

 

read this it should help with your back pressure questions. http://www.hondalife.com/articles/backpressure.htm

You will gain some uptop, I felt that my carsound opened up my top end along with my other mods.
If you're going turbo though you might want to get a bigger cat, but it will be loud and be too big while you're still NA.

 

good info guys, thanx.

 

be prepared for the spatty bee sound

be prepared to possibly lose a little low end power


i think you should wait for the turbo

 

DONT GET CATCO!! their high flow cats sound like a pack of beez.. anybody wanna hear it?? :X
