FI Non res vs resonated CBE

FPenvy

it really comes down to how much volume and drone you prefer.

the more you open up the system the louder it will be but that's where the power is.

CBE adds good power but dropping the cats is where you unleash a lot of the restriction of the stock exhaust set-up.

adding non-res TP's will give you more volume and a little extra drone obviously since the cats are by you legs in location and you remove those there's some extra drone coming in there.

res TP's will give you the power and lower the drone.

HFCs to me seem pointless unless you live in an area that it wont pass emissions or don't have a guy to get around that part lol

Not to someone that doesn't want unburnt fuel smell in their cab. I don't have a CAT anywhere in the system and my car smells like an outboard motor

OP. I love my non-res FI exhaust. No drone what so ever but I also have a turbo acting as a hell of a muffler.

mine only smells on the inside if the ac is on without recirc and at a stop for awhile.

that or windows down at a long red light but it's not bad.

personally I enjoy it

FPEnvy, that 3:07 video was one of the first I watched when I started looking at CBE systems, I thought you did an engine swop at first

I've decided on resonated. Just matter of 12 vs 18. It's a $30 difference, so that's fine. Was seriously considering the 18, because people say that it's close to stock on the interior but I do want more volume when I drop the hammer. decisions decisions...

FPenvy

no engine swap just exhaust swap lol

if you want the least drone and interior noise then go 18"

me I could care less about it. its a sports car and should sound like one to me lol

I don't mind a little drone. For my eargasms, i welcome it. But if it starts causing more stuff to rattle, squeak, creak. Especially in that soft top, then I'll go 18". Wonder if there was ever a poll done 12" vs 18"?

Honestly. It all depends on how sensitive your ears are along with how much "noise" you're looking for in terms of Exhaust sounds. When I bought the NR CF i had only heard a 12" Res + NR HFC in person, and I couldnt stand the added "hiss". And it was a DEEP sound. I would say 12" is the perfect midpoint for Loud (when on throttle) and quiet when cruising. Just know in colder temps (50Fs and lower + cold starts) will be even louder.

I'll post a vid from inside the car later tonight (again it'll be NR CF).

CF = Higher pitch 3K Rpms+
SS = Deep = Entire Rev Band
