what is the best bang/4/buck on mufflers for a stout 340?

I run 2.5" Summit glass packs. Hard to beat the performance of straight through :D. Loud as hell! I think they were about $20 each. They've been on the car for a couple years now, no issues.

I will have to admit that they sounded better when I had them dumped at the rear axle, they drone a touch now at certain rpm's with the over the axle tailpipe set up. Could be because they end right before the stock tail panel, need to get some chrome tips and the tail panel with the cutouts. Still not nearly as bad Flowmasters though, those things sound like crap.
