exhaust...

baflers? baffles produce back pressure wich makes low end torque. no backpressure meens that your truck will be gutless down low and make more power up top(glasspacks) and k&ns may let dirt in if you dont ever cleen them but i doubt you will ever have a problem from runing a k&n.

flowmaster makes more botom end than magnaslow and they sound way more agressive, glasspacks are way to mellow sounding, but some people like that... basicly if your runing  no cats, than you need backpressure(flowmaster), if your runing cats than you can get away with a glasspack and still have botom end power but it wont sound good imo. nothing will outperform true dauls with no cats and flowmater 40s. also dont go to big pipe. 2.25 or 2.5 is more than enough for true dauls, 3-3.5 for a single. if you go to big you will loose botom end power from less backpressure. if your hung up on geting a glasspck than your beter off with a singe system with your stock cat and have good lowend power, but if you want a real exhaust system like true dauls than you need flowmaster.

hey, you know what, i have a flowmaster 50 series that bolts on cat back with 3.5" pipe with a single in dual out muffler with turn down tips right after the muffler which is right before the rear fender. the 50 is a quieter muffler but the turndowns make it about as loud as my 40s out the back corners.it sounds real good, beter than any bolt on magniflow system. it fits 88-95 chevy trucks and is in good shape. ill sell it for 150$. i used to run it with a guted cat and it sounded realy good.
