Opinions Wanted!!! What's the Best True Dual Exhaust System

[leeboy66]

I am interested in purchasing a true dual exhaust system for my 1977 Corvette. What do you think is the best way to go?

Without a doubt, go to a reliable shop. I would not get a kit for this,to do it on your back, plus a H-pipe like I have or an X-pipe is needed (or should I say...should be installed)... It took an expert over 5 hours to do mine...

Have one built by a competent shop.

I used the Mid-America true dual system and installed it myself. I'm very pleased with it. Are you going to eliminate the catalytic convertor? If so,many muffler shops and garages probably won't install it with out convertor(s) as they can get in trouble with the emission police.

Mid America

I bought the Mid America chambered exhaust. Took me 1 hour to pull the old system off and about 3 hours taking my time with the new one. It was pre-cut and shaped and in my case they sold me the shorter set up for headers. That included all parts, clamps and collector flanges for $291.00 shipped. Love the sound and would never go back to a stock system. If your not somewhat handy have a shop do it. I have never had a lot of luck with exhaust systems but this one just happened to go on without a hitch.

Several years ago I purchased a used chambered exhaust set up (don't know the manufacturer) and I love it! I do have a resonance @ 2500 rpms, perhaps a cross pipe would eliminate that...but I do love the loud sound.
I had mine installed by a local Corvette shop. He did a great job and replaced my exhaust manifolds at the same time.
Recently had a clamp come loose and hubby replaced the clamp. We also just bought a welder and he is making noises about welding the sections together.

I got the 2.5" chambered exhaust system from Mid America Corvette (www.madvet.com). It comes in a kit, complete with all pipes, "mufflers", connectors, clamps, and hangers. Although I was able assemble the system together using the connector clamps, I went ahead and had a local muffler shop weld it together. I think it's an awesome system; I was initially concerned that it would be obnoxious, but I am pleased with the sound.

Same system...love it

I got the same 2.5 system. After reading all the pros and cons about the sound I was in limbo for a while before deciding to get it. Glad I did...sounds awesome!! My older (much) brother bought a new 67 and then traded it for a new 69 (wish I had that 67 big block now) while I was still in school and I never forgot the sound of the sidepipes. After all the years of wanting a Vette and finally getting one.... something was missing. I figured out what it was and Im happy with the new sound.

Hey leeboy, I had a local shop build my setup. 2.5" into series 40 flowmasters combined with the lope of the comp cams 292 makes heads turn everywhere. I love pulling into my golf club and setting off all of the alarms that are set too sensitive. peace Bud

i bought all the components for a true 2 1/2 true dual exhaust from corvette central and installed it myself. it took about 45 minutes to get the old system off (a cutting wheel or recip saw comes in real handy, lol!!). the parts fit perfectly and it took me about 2 1/2 hours to install a true dual system with NO mufflers. i bought a set of monza tips with built in resonators and had a muffler shop professionally install them at the end of all my work. great sound and i like the twin dual tips out the back. i thought about using a baffled system, but decided against it because i liked the look of the pipes out the back, not extending down from the stock positions, but that is all a matter of personal taste. if and when i ever need to replace the system, i might just try the baffled system as something different. i like the deep rumble produced by the system and i'm certain it has to help beef up the otherwise stock engine specs a bit by reducing the back pressure a lot. since corvette saw fit not to make major frame changes, the center crossmember is already set up with 2 openings to accept true duals without the cat convertor.

This is all assuming that you don't have emission checks to deal with?

If you don't, then I'd suggest a good set of ceramic coated headers, from a mfg such as Hedman or the Hooker Super Competition. From there, I just went with straight pipes back, then got the necessary bent rears from one of the Corvette Central / MidAmerica / etc shops for the rear. I then put Cherry Bomb glass packs on the rear because they had the right mounting angle to have them straight out the back.

Do the 77's have the exhaust through the crossmember?

BTW...I'm redoing my exhaust this year (hopefully) and having an X-pipe added. That will requre me to go to a shop and get custom bent tubing. I'm finding more and more from reading professional opinions that X-pipes function better than H-pipes...for whatever that's worth.
