Exhaust sound
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?

Re: Exhaust sound
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. Last edited by tf95ZR1; 05-05-2014 at 12:55 AM. Reason: Wanted 2 |

Re: Exhaust sound
That sounds like a hardware rattle to me, from here anyway. Our car is a Borla with mix of piping (headers, no resonator, kludged cats) but there's nothing tinny about it, inside or out of the car. Does have quite the drone at times from idle to 2400 or so. Of course I've only heard it from outside the car a couple times.
Cheers, - Jeff

Re: Exhaust sound
Yep, "tinny wraaaa" sounds like a loose heat shield to me. I've had problems with those on both of my Vettes. It will generally only occur at a very narrow and specific RPM range.

Re: Exhaust sound
Don't know what it could be - there are no heat shields on this one. But Yeah that's kinda what it sounds like. Have to see if I can get a vid of it here in a day or two.. I got under the car and retightened all the bolts thinking that might be it after having driven it several miles but that didn't change it a bit. The only thing I can even imagine I might have done different is that I used a new "old" header collector gasket on the passenger side flange since the stock one that was on there was torn up when I took off the stock one. The gasket I had matched the holes so I figured it was good??
