Hi everybody! I am a proud new owner of a 2006 Silverado 1500 2WD W/T with a 4.3L engine. I've been doing my fair share of lurking and have been wearing out the search button. I have found out tons of info on here on many different subjects and am thankful to find this site with good people. Anyway I've been sorting out my plans already for my truck and the top two things on my list is a K&N CAI and new exhaust. I plan on leaving the cat on and purchasing a single in-out muffler. My problem is finding a muffler to suit my needs as there are tons of choices out there. I am wanting a low rumble sound obviously, hoping that won't be hard to come by considering I have a v6. I know there are tons of topics on this subject for the v8 guys, but I want to hear your opinions on what will sound good on my truck. I think I narrowed it down to the Flowmaster 40 series or the Cherry Bomb Vortex, also there are many tip choices on the Cherry Bomb website which is a plus. What do you guys suggest? Another question I forgot to mention is pipe size, should I go with a 2.25" or 2.5" pipe?
