Default 1987 exhaust question

I just purchased a 1987 corvette L98 coupe. Noticed the exhaust is a little on the loud side. Looked underneath and noticed that super turbo was the muffler type. Can anyone out there tell me what type of muffler would give me a nice rumble but not drive me out of the car in the low gears?
Thanks
:confused:

There are plenty available but some get pretty costly. I like the way borla sounds. I also like power effects but they are of this students budget. Your probably getting alot of interior resonance. They came on my 84 when I bought it. They were the first to go. Since the 84 wasn't a "speed demon" i had them replaced with some stock mufflers.

When I got my 87 it had an awful resonance at low RPM - drove me NUTS! Upon further inspection I found undersized mufflers from Midas. :eek: I replaced them with GM stock and the resonance was gone and they sounded a whole lot better.

concur with the flowmasters and straight pipes- had them for years now, never picked up on the resonance thing- reasonably quiet till you stand on it, then it's pretty rowdy, darn it.....(!)

Super Turbos have a nice sound. I like them better than the flowmasters. :flag

Eliminate 'em. :)

Mufflers are worse than body kits, what do they do? They just muffle, there is no performance value, nor do they do anything for the environment. :)

I'm running a single cat, two birds with one stone. It muffle's and it cleans the exhaust.

I have no cats and no pre-cats, just some pipes leading to a pair of Dynomax mufflers. My goal was not performance (though I imagine I did get some) yet to quiet the car down! It's quiet on the inside and loud on the outside. Y'can't ask for any better than that ;)

Is the rest of your exhuast stock? I have heard the dynomax muffler on a Vette but in general, dynomax is one of the quieter mufflers.

I really don't know. But it all looks to be fairly new judging by the condition. One of my mechenically inclined friends said I could just replace the super turbos mufflers only. I think what I'll do is wait till the spring attend a few Vette shows and listen to some systems on other vettes. :rolleyes:
