All I ever see available for converting to true dual exhaust is an x-pipe, but I just prefer the old fashioned rumble you get from an h-pipe versus the raspy sound an x-pipe makes (h-pipes tend to have less part throttle drone as well). I know the muffler that's used has an effect on the sound too, but even with V8's I heard that have an x-pipe they also have a bit of a raspy tapping to the exhaust sound which is distinctive to the x-pipe. The V6 needs all the help it can get in making the exhaust tone sound deeper and fuller, with only 6 firing pulses coming down the pipes it's hard not to end up sounding like a ricer, the raspy tone an x-pipe adds to a dual exhaust doesn't really help that. I'm not trying to reinvent the wheel here, I know the cheapest and easiest way to put a dual exhaust on is one of the aftermarket x-pipes, but I'm just trying to enhance the sound as much to my preferences as possible without spending a fortune on a completely custom built system. I wonder how hard it would be to modify a take-off GT h-pipe to hook up to the V6 down tubes behind the cats?
