Thanks for this information. It seems HKS along with most other japanese exhausts voluntarily comply with JASMA noise guidelines. This is the only thing that bothers me as i dont want to spend good amount of cash on an exhaust and then barely be able to tell the difference from stock.
I didn’t personally install it, but the shop said it fit like a glove. You’d expect that kind of thing with Magnaflow, so I’m sure it’s an ideal fitment.
Hi Mate, yes it's significantly louder than stock by a fair margin, inside the cabin you now hear this nice deep rumble trombonish sound, it's not obnoxious loud and might be too low for some though, for me it's just fine, basically it's exactly what you hear in HKS's video:
Would you happen to know the db for Nismo’s Street and Track variants?
I was mainly just referring to not having any interest in putting dual 2.25" aftermarket exhaust on the car. It would be fine for an otherwise stock car that doesn't plan on getting tuned or installing aftermarket downpipes.
The Nismo trim has the same exhaust as the other trims (varies only by transmission), it is not the same as the aftermarket Nismo offerings.
I have the Borla ATAK, and I love it. Absolutely great for track driving, I can actually hear the exhaust, where my brain can process shift points while wearing helmet, amongst other cars.
Quick question when you say pops and burbles is your car tuned or stock and do you have factory down pipes or aftermarket?
thats great to hear. How was the fitment of the borla ATAK? Was it good in your opinion? Also, do you think it is loud enough to require ear plugs during normal street driving? Thanks for your time
Borla ATAK fits flawlessly installed correctly, you need to ensure you get the pipes slid in completely. If you don't, it will potentially rattle against the W brace.
