Any opinions on an aftermarket exhaust system for a '00 5.3 L silverado? i'm wondering if anyone run true duals or a catback gives pretty much the same performance? anyone try the summit exhaust system? i think it retails for about 129.99. also, any long tube headers for this truck at an economical price?

thanks in advance for all replies

Get a Magnaflow cat-back from hottexhaust.com......I installed mine last week & it's awesome.

 

I run TOG headers and run a one chamber Flowmaster and i also have a cut out too. For long tubes I hear the ASM's are nice headers. And everyone here has differant opinions on mufflers.

 

I have AS&M headers very nice 702.$ at my door. I a Magnaflow muffler and custom Exaust it sounds very good no drone what so ever.

 

WHat kind of gains did you get with those AS&M tubes? How much different does the exhaust sound with 'em?

 

I gained all thru the RPMs. The sound is hard to describe I guess you can hear the valves moving maybe even tinging sounding.
