Got the exhaust put on today. I decided to go with NO MUFFLER - 4' of 3" pipe instead, then split to duals with 3.25" chrome tips out the back. I must say that the thing sounds nice. It is a low smooth rumble, but it is nice a quite at idle or on the hwy. I didn't expect or see any significant power increase, but it sounds like a beefy V8 now. Thanks for all of the input you guys have given me. One question, should there be a hole in the bottom of the tips to allow moisture to drip out? Thanks again, love the new system. Levi
