I have a gtech, my car has run 5.3's to 60 mph and also gained 30 rwhp through different exhaust setups on a standard engine. Sure it's a 304 but the theory is the same. I've gone from 9.4 1/8th miles on the standard exhaust, to 9.2 on a 2.5 inch cat back, to 9.0 on long headers into twin cats into 2.5 single. To..... who knows but +15rwhp on a full dual system that finally has let the headers to there job and is by far the biggest gain I've have had from any of those systems, I know exactly what gains came from what system (it's had 4 different exhaust setups on it so far) and I have no doubt it's still alot quicker straight out of the headers (which are 38 inches long with 8 inch collectors).
You can do the same on the V6, but you need good headers first a good merge to help scavange the collectors and then whatever gets it out to atmospheric pressure with the least restriction possible. The point I was trying to make is that all your gains on the exhaust are from the header/collector and your merge after that nothing matters so long as it has the least restriction possible. All race exhausts end at that point
