What the hell is LPOTY?

hello there l have a 2006 hd sierra, what you truck guys are missing is that when your catalytic converters plugup your exhaust is not working very well,l'm thinking of magnaflow catback system,l know there is some cutting of the pipes but they don't offer what l'm after,so look's like l'll be cutting some of pipe no problem.l know the sound will come out great!don't be scared to change out your catalytic converters too.l had a 97 chevy sliverado and change the cats with new flow-master big differance.sold the truck milage was high sorry to let go but l'm happy with my new beast.when add cold with exhaust you will notice a big differance in power!there is no need for power chips or programers you can achive stock power with exhaust and cold-air intakes. HUH?

Ok, time for my .02 Lots of people here like to bash on flowmaster, and thats fine. But remember that flowmaster has more than just one muffler available. Yes, while the 40 series are loud, there are other series that are not as "rough" souding. I only have the 5.3L with a 40 series flowmaster, mine is pretty quiet at idle, loud on acceleration, and very little drone on the highway. I dont know if my truck is well insulated or what but my flowmaster is quieter then a knock-off that i had on my old dodge. I agree with the statement earlier that the best thing to do is go to shows and hear fisrthand what ppl are using.
