Well guys,

Since I've already got a Magnaflow resonator on my RX-7 and I like it, I followed HAWAIIZR-1's advice to order one for my ZR-1. Only got to find some good headers now!

I beg to differ.
I believe in having fun with my car. If that involves time and money, so be it. If I wanted to invest, I would have bought stocks.
What 5AVI VT has done so far, I wouldn't call crazy modified. Not yet anyway.
Lastly, I disagree that it looks like something from Europe. Not that any European exotics look bad, Corvettes always look very american.

Life is short, do what you want and enjoy doing it. Don't care to be a caretaker for the next guy.

No offense.

Lmfao no offense taken. I'm just not sure where that outburst came from. You mad bro? And for the record I work 12 hrs 7 days a week i'm no stay at home mom. Thanks for your input on resale. Never asked for it and don't care what you think nor will I ever!

Anyways was just providing input on the exhaust setup. Never claimed it to be anything special or custom or godly. Just a corsa exhaust on catted sw headers. And I was simply saying it may sound louder than it actually is because I have a microphone on the back of my car.

The Corsa brand is very viable and I like Corsa exhaust a lot but be aware that only one tip in each muffler is functional. I suppose this means one tip in each muffler is fake? Strange.

The C6Z06 flapper valve does the same thing. Wi one tip closed off, it significantly reduces drone and noise. Unlike the Corsa however, I can open up the second tip by flipping a switch in my console and gain some additional HP relieving the back pressure. It also makes for a louder and deeper rumble.

As has been noted many times over the years, dual tip Corvette mufflers either stock, Corsa or possibly some other brands have one clearly open tip and one completely or partially closed. The closed tip is there because some portion of the muffler is a closed chamber called a Helmholz Resonator which effectively eliminates our infamous drone at one of the two most annoying frequencies or rpm points (Corsa calls them "Quarter Wave Tuners"). On older Corvette dual tip mufflers there was a small approximately 3/8" tube in the non operational tip that did flow a small amount of exhaust through the Helmholz Resonator directly from the main pipe without adversely affecting its resonance cancelling ability. Many Corvette owners over the years thought they could improve the sound by opening up the non-functional side and ended up very disappointed to discover the sound was worse and there was now resonance. There is no effort on the part of manufacturer to deceive the public with "fake" tips. The dual tip look is cosmetic and the Helmholz Resonator is there for a purpose. --Bob

this. take a look at the c6 design. the flappers allow quiet crooze

so I can offer you this buy my B&B exh, and I have a pair of c6 tips that can be grafted on.

the b&b will go for 650 plus shipping, and I need another 200 for the tips

PM me if interested.

Interesting response from you Bob but with all that said why is the B and B Exhaust so highly touted for the ZR-1 when in fact this system has drone that some say is very bad. Clearly Corsa has no drone but some people can't get past the non functional or fake tips. I like the Corsa but I also think stock is very good also. I'm not crazy about how the Corsa tips sticking out past the bumper where as stock does not. I love the B and B for the ZR-1 because the tips look perfect and the sound is the best but the system still has drone points and B and B has never admitted to eliminating the drone. Comments Bob?

well I'm not bob but I have a comment. there are a few variations on the B&B the old systems were more free flowing but would rattle your teeth out with drone

the newer systems went to a more restrictive muffler design which helped and they are very "streetable"

with the x pipe and headers I find them not bad at all unless you drive in 6th gear at 1500 where the engine is lugging

I've got 4.10s in the rear and anything above 1800 rpms is just fine with the x pipe and new design B&B
