i forgot to say i would also do headers with the exhaust... ive heard that true duals would hurt bottom end power??

not if you use 2.5 with the x pipe .when i took the x off i really did lose some low end.

what muffler do you suggest. i dont want it too loud, but a nice sound
01 Silverado
also, for someone who knows more about this stuff than i do, will headers for the 6.0 work for the 6.2?
01 Silverado
Dont know about the 6.2 but a good sounding muffler is the Flowmaster super44 imo
the super 44 seems like it might be a little loud, i was looking at the 40 series delta
01 Silverado
Don't know if they will fit 6.0/6.2 but if you are going to do headers do LT's shorties will not help HP boost. True duals with dual HFC's and Flowmaster's sound great. This set up will help with low end power. You could look at Truck Accessories, Auto Accessories, Auto Parts, Car Covers, Tonneau Cover and Seat Covers to see what fits then look at www.texas-speed.com for a good price.

well if you want quieter, just leave the stock muffler on and pu on a cut out for when you wanna play.
