FS: Lightweight exhaust that meets SCCA autox sound levels
I have a C5 Corvette complete exhaust system for sale that I used on my SCCA autox car. The total system weighs 51# (26# for headers). The headers are LG super pro longtubes. The center muffler is a Burns stainless 3.5" 2 stage muffler with Burns built 3" inlet and 2.5" exit y-pipes. The over axle pipes are 2.5" titanium from a Corsa Ti catback system. The small rear mufflers are 2.5" Burns units. The system will meet the 100 dB limit with just the center muffler and turndowns on a C5 SSP car... I added the rear mufflers to quiet a more modified engine.... More pictures available here: http://s126.photobucket.com/user/ste...y/C5%20Exhaust

We have a 91.0 max reading in San Diego. Think it would pass that with all 3 mufflers on? If you get 91.1 + you need to make a change to be allowed to run again. Is there anything in your mind that you could do in grid to "make a change" like those Supertrapp mufflers?
Do you have a video with sound?
Do you need to tune the car because the cats are gone?
Est time to switch stock to yours?
What make are the headers?
Thanks.

This exhaust was setup to meet the 100 dB national sound limit... and it only just does that. I'd say there is no way it would meet 91 dB in it's current configuration. I'd recommend a tune when changing to a free flowing exhaust. The headers are LG super pro. I don't have any idea how long it would take to change stock to this... not in a few minutes for sure.
I'll dig around in my archives for a sound clip.
