Tail pipe halfsies?

Thanks Bob.

Since I'm fully confused on exhaust modifications, I'll employee the first rule of "Rocket Travel" which is "When in doubt, do nothing different." I'll run my stock for a while.

BTW... I'm from Lake County. Raised on the Chain O Lakes and lived in Grayslake.

Hi Bill--
Well, we got our first snow yesterday--a couple of inches of wet heavy stuff. I am sure you don't miss that!

You may have seen other posts on this subject, but what I did after 20+ years of various loud exhausts on my ZR-1s was to return to my stock '95 exhaust (since the late model system has a low restriction resonator) and I added electric cutouts in front of the mufflers. Best of both worlds--stock look, quiet sound when I want it and anywhere from a low rumble to wide open straight pipes if I am racing or just want to scare small children. If you search for "cutouts" you will probably find lots of detail on mine and others. My system on the '95 (which I sold last Feb) had headers and no cats. But nothing wrong with doing nothing. The stock system still sounds pretty good if muted somewhat. Take your time and listen to as many systems as you can to get a sense of what you might like. Overall, simply enjoy the car-they are really a lot of fun. --Bob

Bill,

My '91 is full Stainless Works, headers to tips, you can listen to mine and Dave's Corsa system this weekend in Buffalo..

I've got SW headers and Corsa from the headers back with no cats. Plenty loud with no drone on the highway. You'll hear it when we drive down. See you Sat morning!

Thanks- I'm looking forward to "hearing" everyone's opinion on exhausts.

(yes, my wife thinks my jokes are bad too)

Don't buy mufflers with dual outlets unless you want to limit your trips to 25 minutes or less. I had made up some c6 NPP vacuum actuated valves for my stainless works mufflers.

You can hear the drone in this video- it is worse in the car.

No, sadly, the long tubes and LS7 cats had to come off to pass the visual part of the inspection. Depending on if I still have the car in 2017, I wanted to do aftermarket mufflers on my stock exhaust set with bmw vacuum actuators I have.

The big 3" SW catback with their fairly loud mufflers still droned lugging in 6th gear, but generally speaking, it didn't drone with the flaps closed.

Bob, those cutouts ahead of the mufflers look slick.
My car has headers, no cats, no resonator, and a 3" X pipe and 3" B&B system all the way back. It produces the dreaded drone, but I'm a masochist and love it. The loudest version is to drop the mufflers at the track. A 50lb. weight saving, and the nastiest shriek a stock Corvette can make. (and a 2mph. increase in trap speed.)
Your conversation makes me wonder if 3" mufflers with Helmholtz tuning are available?

Actually, Bob, that is exactly what Marc Haibeck has done since he bought his car in 1993. He welded three bolt flanges just ahead of the mufflers and always removes them for a drag race. Gets a weight saving but also says it is a bit of a pain in the butt to remove them each time. Said once that if he had to do it all over again he would probably do what I did. I really don't know what aftermarket mufflers are out there with Helmholtz resonators today, other than Corsas.--Bob
