I have been doing some research and getting different opinions,
I first wanted to go with true dual straight 2 1/4 to turbo exhaust but was told it would sound lousy.

Second option is to go with 2 1/2 to3 to a resonator back to 2 1/2 to turbos. I have been told this is a better option (sound Etc.)

My goal is to have a clean sounding not extremely loud system that will handle a 10% pulley and a custom chip.

I have an appointment with the exhaust shop Friday AM and donít want to make the wrong choice.

Please let me know what works best.

Thanks, Scott

True duals usually provide the best flow, perhaps a resonator could be fitted to each side for sound. Many have had satisfactory results w/o true duals, using upgraded/deleted cats & mufflers. Porting the exhuast manifold always helps.. ported manifolds are said to be adequate for up to 400 bhp.
