As for duals, the thing we've found with full dual exhaust is that it tends to hurt low RPM performance a bit but makes up for it at higher RPMs, especially with high flow cats. However, unless you're really looking for top end performance, we generally recommend avoiding this setup. We've had more than a few customers say that they've actually gone back to the SIDO setup because they didn't like the way the low RPM power felt.

I look at an exhaust change more as a way to change the tone of the exhaust and less as an overall performance modification. There are certainly some gains to be had in each configuration, you just need to decide beforehand what you're looking to achieve with your vehicle.

Thanks, Bill. I'm just looking to get a little more fun and driveability (and maybe a little better MPG) out of my truck vs. blowing people's doors off or ear-drums out. Great "every day" advice!
