Default Exhaust question

Hey guys,

Quick question...

What's a Good true dual exhaust system i could install in my 4 speed 1973 corvette?

I'm thinking of buying Summit Racing headers with 2.500 in. Collecter diameter.

I'm not looking for a loud obnoxious sound, I want my car to have a smooth and deep sound. And nothing to expensive

Thanks for the help!

Corvette Central makes entire dual exhaust systems from the header gasket all the way out to the tailpipe. Block hugger headers, tho, that's the only drawback. I'm pretty happy with mine so far, tho.

Those headers in the link won't fit your 'vette, did you make a mistake when copying the link, maybe?

There ya go! (too bad they are not the same price, huh?) I was looking at these a few weeks ago, and asked the forum about them. Several people said they were good headers, no fitting problems, plenty of clearance, plenty of ground clearance, no problems with getting at spark plugs or header bolts. I decided to save up and get some Stan's tri-y headers, but they are almost $500.00, so it'll be the block huggers I have now for awhile.

Ok, what are some good exhaust systems that could compliment these headers ?

What's a good brand of true dual exhaust systems?

Does Corvette Central sell the 3" pipes alone with the MagnaFlow mufflers without the headers or can i just buy the performance pipes

I have those headers and the CC exhaust on my '81 and the mufflers are too quiet for my taste. If I had a '73 like you, I would order the headers and get the Flowmaster exhaust kit. I had a flowmaster kit on my '81 Camaro and I have one currently on my Silverado and they both sounded great.

If I could fit the Flowermaster kit on my Corvette with out the crossmember mods it needs to fit it I would have went that route.

You don't need 3" exhaust for a 350, 2 1/2" are more than adequate. Personally I would use the Walker-Dynomax Turbo mufflers and have your local exhaust shop fit some 2 1/2" pipes.

Ok, but I would need to reducers in order for the pipes to fit the headers I want correct?

No, the headers come with "reducers" that bolt up to the headers. I have the Summit headers as well. They come with reducers that are necked down to 2 1/4" already read the fine print "mounting hardware, and 2.250 in. reducers are included". You just cut them back to where the 2 1/2" pipes mate up.

Hey guys,

This is what I got so far:
Headers:
http://www.summitracing.com/parts/SUM-G9003/

Pipes:
I'm thinking of just reusing the original pipes since I don't think I makes a difference.

Mufflers:
For mufflers I'm thinking of using the Dynomax performance mufflers

What do you guys think?
