For any of you not completely satisfied with the sound from your sidepipe exhaust, I have converted my '04 Viper to a very simple out-the-back design. I loved the idea and look of the sidepipes, but to me the stock system sounded like a UPS truck, so I tried the Corsa Track system. Big improvement, but still not what I was looking for.
My basic idea was that a better overall sound would be produced if the pulses from all 10 cylinders were joined together and emitted at one place rather than two. The design consists of heat-wrapped 3" 304 S.S. with mandrel bends and a crossover connection forward of the differential. The crossover is critical for two reasons. First, it helps to premix the sound pulses before exit, more effectively than the stock crossover, and helps to equalize the pressure between the two sides, like the classic "H" pipe. Secondly, and I can't explain why, the noise level is dramatically reduced. So much in fact that I eliminated the mufflers! Just the stock cats, then 3" pipes all the way out the back. It bolts in easily, uses the stock hanger locations and weighs about 15 lbs. less than the stock system. The sound is more like that of a healthy V8 instead of the uneven V10. There is some resonance, but to my ear, it adds muscle to the sound and overall the improvement is huge. The car now has a sound that matches it's looks and horsepower. Feedback from those riding in the car and from those that have heard it pass by has been very positive. And, now it doesn't spit water at me when I get in or out of it and it's running!
I closed off the sidepipe holes in the sills with wire mesh similar to that used on the grilles of some high end cars. It looks great and allows a subsequent owner to easily convert back to sidepipes if desired.
If anyone is interested in having your local exaust shop duplicate this system, I can provide additional information, photos and even sound files.
