I had mine installed this week. I chose the Corsa Track with NO crossovers, and with the 3" intake diameter (vs. the stock 2.5). In addition, I installed the 3" in, 3" out, Random Tech High Flow cats...
In short, I'm going to change. I was hoping for a deep, throaty, muscle car sound. What I got was a raspy sound, not low pitched at all. Basically, my Viper sounds like one of those Honda Civics with a coffee can for an exhaust.
I guess I shouldnt be surprised.. If you think about it, I now have 5 cylinders, with about 4 liters, on a single exhaust system. Not alot unlike the ricers...
If I had to do it over again, I would at least install the crossovers, that might help it sound like a 10 cylinder instead of a 5 cylinder.
The car IS loud.. I like it that way. The car sounds better from outside than inside. The car is WAY WAY WAY cooler inside. The sills barely get warm.
I just hate the new sound.. oh well..
I really can't tell that much difference in power. Past experience tells me that more noise is sometimes misinterpreted.. It may sound faster but might not be. I'll spin it on the dyno one of these days and see if there is any significant change.. Not that it matters, I didnt do the exhaust for power, I wanted better sound..
What I really want is a nice muscle car deep rumble, lumpy, at idle, at a 10 cylinder roar at throttle, like the V...ttes and others get so easily.
Just my .02..
Corsa's will be removed asap.
