Dual Exhaust options - mandrel bent or not? and mufflers

[Mattchu60]

Hey all, I'm putting new exhaust on the truck - I'm going to do a manifold-back system. Looks like I have 3 options for that - Dynomax, Flow-tech and a Hooker Headers system - all are 2 1/4". The Dynomax and Flow-tech are both around the same price and have crush bends, the Hooker Headers system is madrel bent.

I'm running an 87' k10 with TBI 350 - not a big powerhouse engine here. Is there any benefit to going to mandrel bent system over the crush bend? Its about $140 for the Dynomax and Flow-tech, and $220 for the Hooker Headers system, so $80 more. Same guage steel for all 3. My thought is go with the flowtech system, as it has pretty good reviews.

Any thoughts on mufflers? I'd like something pretty quiet, but a little more than stock. I hear good things about magnaflows. Any thoughts here would be helpful.
