F.I. :: About to pull the trigger... give me some input

HIZZY

I want to go with just the CBE...
non-res :: CF cans :: SS tips (will def look better on a white nismo)

I'm in it for the sound & the power gains.
but don't really see the need for an extra $500+ for minimal gains adding the HFC

The nismo is too quiet for me stock

check this older thread.... (from my CBE vs. CBE+HFC issue)

The great HFC question for newbies

So which is it noise or power gains? Sorry doesn't seem like both here. Cats do both, and everything adds up.

I can see saying the cats aren't worth it because a tune is recommended. However that would again result in more power, and a car that is more responsive. I could also see maybe even not wanting to deal with the install.

The cats are roughly a third of the cost of the exhaust you are looking at, and you are still saying they add roughly a third of the power at least? I'd say that's substantial. I don't think anyone would deny that factory cats are the most restrictive part of the factory exhaust system.
