[Official] "Which Exhaust Should I Buy for My 370z?" Thread

[bigdog1250]

F.I. Non res. I've heard HKS next to the FI and it just doesn't sound as deep or mean. I can't speak to the resonated FI systems, but it sounds like non-res will be the way to go for what you're looking for.

I've heard FI in person, but it was just a rev or two, not under load. It sounded really nice, but I decided on Berk for a "normal" muffler look rather than the canned-muffler look.

Fast Intentions all day. i originally was looking at the HKS system but after a talk with tony at FI i was sold. after installation i was so happy i went FI rather than ANY other system.

Thanks for the answer. some youtube videos make it seem like the HKS tone is deeper, and other videos it seems like FI exhaust is incredible deep. Would the berks HFC be too much with the non res exhaust?

Both are great options, you can't go wrong with either

That being said I like the HKS since it's less common on the Z34 but the Fast Intentions sounds better on stock cats

I've got the HKS, with Z1 HFC, and it sounds perfect. Not too loud, not too quiet, well till you get to around 4,000 rpm, then it opens up.

Sorry I didn't clarify the Fast Intentions was on my G35 coupe and I sold the car so was the exhaust. As for the FI, I really can't find anything to complain. It sounds awesome I loved it. The HKS has a different tone. Sound not as deep as the FI at low rpms. But it's louder and sound exotic at WOT under the load. You really can't go wrong with either one. I still suggest to attend some local meets and hear them for yourself.

Being lowered 1.5 inches is lower than any springs out there and quite frankly that is slammed by most people's standards.

You'll be scraping more than just the exhaust at that point trust me as the front sport chin spoiler scrapes like crazy and I'm on H&Rs which only lowers 1.3 front and 1.0 rear.


My vote FI FTW...

Fairly sure the FI exhaust doesn't hang any lower than the stock exhaust. More than one person has stated as much.

If you'll do a seach on here, you'll find several review threads from happy F.I. customers.

You won't find many reviews on HKS as the price doesn't justify the comparable gains to several other systems for 1/3 the cost.

If you are looking for an F.I. exhaust setup, they also make HFC's as well if you wanted to look into that option. However I have personally heard the Berk HFC/F.I. CBE setup and think it is AWESOME.

If you're looking for the exhaust to be loud and proud, but not obtrusive on daily driving, and plan to get the Berk HFC's, I'd recommend going with the 18" resonated, Stainless Steel Muffler F.I. CBE setup. It will keep down the volume while cruising, but wake up when you get on the throttle. The perfect combination of performance, sound, and cost effectiveness.

Not to thread jack but any recommendations with ART pipes? Stuck between GT-haus axle back and AAM mid pipe, FI, Top Speed, and HKS.

I have HKS and love it, but from your description I wouldn't recommend that exhaust. HKS gives a low gentle sound but roars once you rip it open, plus the power gains are a plus. For the loud, deep, and beefy sound I would go with FI
