Hey guys, yesterday when I came back home I found out that my maxima original exhaust is falling a part, my actual set-up is cattman Y-Pipe + Powertech muffler and stock cat + stock b-Pipe with resonator. I want to order a Cattman cat-back + Headers + high flow cat, said so what kind of gain can I realistically expect ?

Thank for any input.

Cheers

I would guess ~ 20 hp. Only a dyno will tell though.

Don't waste your money on a high flow cat imo.

I still have the original cat, while I'm going to replace everything I though why leaving the old cat there ? I mean Nissan is asking like 500-600$ for a replacement cat, no way I'm going to pay that kind of money for a catalyst.

I didn't want to put high flow cat for performance cuz I doubt that there will be any gain with it, it was more like why leaving that older piece of crap there while all the rest is brand new.

Cheers
