And still cheaper than just about any C5 aftermarket exhaust, not to mention the adjustability!

Hey Speedy. You were my inspiration on this. We did some testing with them in a bunch of different locations and when pointed down and because our cars are so low, it blew crap everywhere from the ground and my concern is it blowing stuff up into the body wiring and other areas. Then we turned them to their current direction and did a smoke and temp test. The smoke actually, follows a line well under the spring and after 5 minutes of idle time, the temp only increased on the spring by 5*.

My concern would be at speed, specially hard running at speed. You may want to put a temp sensor down there near the spring while driving to make sure. I turned mine down and back at about a 45, then sawed the pipe off flat with the bottom of the car and I'm still a little concerned about spring temps. Those springs are plastic! And at speed you are going to have upwards of 1000cfm of hot air flowing under there.Another thing you may want to look at would be a stainless shield in front of the spring.

Your my hero Dale. I appreciate your comments and ideas especially, the stainless shield in front of the spring. That is an awesome idea. Perhaps even with some type of heat shielding on the front side of the shield.

98. Yes, you can put these on a stock vette. I am already north of 450rwhp and did mine mostly for the scare appeal but i am sure you can get 10hp out of a stock set up. Just my opinion of course.

Two layers of stainless separated by a thin layer of air will do wonders!
I bet with 450rwhp+ those things do sound good!

They really look great! However if you all are going to be so picky. I'd change the position of the exhaust clamps. It looks like the bolts are the lowest thing under the car, I wouldn't want to drag them on the ground going up or down a driveway, etc. Thanks for the great pics!

FYI, rear spring is fiberglass - not plastic 
If you're really concerned about it, maybe just buy some muffler/cat heat shielding from Summit or something. It's aluminum/fiberglass wrap basically, designed to reflect heat and insulate from it as well. $25-50 and reusable.
Personally I plan on adding this soon, though I've had open cutouts with no turndowns for years without problems.
