Should i put a flowmaster 40 or glasspack on my Chevy?

I have a 1992 chevy silverado V8 (350 motor). I'm putting a new exhaust on iy, im not going to do straights or anything just a muffler and then a downspout on it. I want to know which will sound better and which has a better performance enhancemnt.|||Between the two, the Flowmaster has a better all-around sound. Regarding the 'performance enhancement', its really a wash - both will give you a minimum improvement, since the exhaust piping is just as much of a problem as the restrictive stock muffler. The 'crimp' bends in a stock exhaust contribute more to the exhaust restriction, and while you're putting on the exhaust, you should seriously consider upgrading to some mandrel-bent tubing and a high-flow cat.



The glasspack sounds good, but it allows a lot of bad resonance to come through. If you like your exhaust with a lot of cackle-and-pop, the glasspack is better. The flowmaster will still pop, but it sounds a lot lower.



There are still other mufflers out there that may offer even better sound, depending on what you want to hear.
