Exhaust sound - ZR-1 Net Registry Forums

Vetman · 05-04-2014

Borla exhaust has been on my z since I have owned it. I love the sound, especially as rpm pass 2000 to 2500 under light acceleration. Anytime a car is along side me drivers usually take notice when I run through that rpm range. My question is does stock exhaust and after market exhaust have the same or similar menacing sound at that rpm range?

Just installed a Corsa, no cats, SW headers and it sounds very healthy plus NO DRONE!!!!

I have the SW's and no cats. Just need to install my corsa's. What catback are you running?

I have a Borla exhaust and also love the sound.
The problem is the resonator REALLY robs you
of HP. I replaced the resonator with an X-pipe
(and headers) and WOW! Yep, resonance
around 1800 rpm but for me that's OK.

Stock exhaust makes NO noise whatsoever; far too quiet for these cars, in my opinion. Even a stock exhaust with the resonator removed makes virtually no noise. The aftermarket systems all sound different but all add sound over stock.

SW's, no cats and Corsa. Sounds good to me.

Just add cutouts and you can go from mild to wild sound with the push of a button...Bob

Bob,

Do you still have the stock resonator however?

FU · 05-13-2014

The blue car will have the same setup Bob. Looking forward too that.
The white car had the same setup but with the big flowmaster mufflers , again too noisey. I want quiet , untill the right time. Then let her rip.

I see I'll have to loose the spare........maybe use QTP's oval units.

Hi Frank--I will be working with Marc later this summer on getting the cutouts into the position that Tony D has his manual ones. I would like to remount the spare carrier and I think it can be done, at least based on my preliminary research. If we can get it done I am sure Marc will let his customers know. I looked at the low profile units from QTP for positioning along the pipes just before they bend around the spare but I would rather re use my round ones and put them farther back. We'll see. Also I saw your car at Marc's when we were there--looked good. --Bob
