loud exhaust
I have a 1986 vette and installed a B&B, Tri flow exhaust system which is loud in the compartment. I put insert reducers in the exhaust pipes, it helped a little, I took the rear wheel wells off and sprayed sound proofing in the area. I also took all the carpet out and installed Dyno mat sound proofing. Can you suggest anything else. It's loudest on the highway.

Re: loud exhaust (iperez86)
Before you dump too much $$ into soundproofing your exhaust, have you considered selling it, and buying a Corsa? I haven't heard a single complaint of interior noise...

Re: loud exhaust (McShagger)
I have an 86 and here's what I did.
Since my Walker mufflers have twin tips, I simply stuffed one (one on each muffler) with balled up aluminum foil (yea, the kind from the kitchen).
I first stood behind the car with the engine idling and determined which tip was flowing the most exhaust; that's the one I chose to stuff full of foil.
I used a wooded broom handle and a hammer to make sure each ball was tightly pack into the muffler tip and kept adding more and more ***** of foil until that particular tip was full.
The sound difference was dramatic and made me feel like I was driving a totally different car. Of course WOT power will be down because of the increased exhaust restriction, but it makes street and highway driving a dream.
I first tried using steel wool pads, but they didn't last as long and at WOT would heat up a begin to glow red hot. Then the pieces would break off and get blown out of the muffler at WOT. Going down the interstate I look like I had Roman candles for mufflers, with all the pretty sparks flying out the back of my car.
If you run WOT for any extended period, the foil will eventually blow out, but for normal driving my car was quieter than stock.
Another point is it's easily removed using a long drill bit chucked in an electric drill (I bought a 24" bit from Ace) incase you decide to race.
Hope this helps.

:confused: I can't figure out why you would intentionally plug up your exhaust. You would be MUCH better off getting quieter mufflers than purposely restricting your exhaust if noise is that much of a problem.

This is an easy one.
I just got tired spending my $$ on new mufflers. I bought three different pairs, all claiming to be quiet. The Quiet Flow mufflers that I'm running now were hyped to be as quiet as stock, which they "ain't".
Yea, I'm running full length headers and the rear pipe has the balance tube (TPIS stuff). I did the insulation under the carpet bit too, both front and back.
The next thing I intend to try is extending the exhaust tips farther out to see if that makes any difference.
When I was a lot younger I probably would have appreciated the sound, but at my "advanced years" that sound no longer holds much appeal for me.

One last point. If you check the Tech Tips Section on this Forum you'll see my solution (as well as some other things to check) listed there.

Re: loud exhaust (JAKE)
You can plug up one outlet on each side to make it quieter when you dont want it loud, extend the tips past the bumper will help too.
Crossover pipes help, soundproofing material helps, but unless you actually plug up one side theres not much you can really do.

Exhaust note is a very subjective thing; music to some but a constant annnoyance to others (like me).
If you're really bothered by it, plug off one tip. If you like the cop-calling stereo sound - well, I say, to each his own.
