Not much different, but it sounds cool when you open the pass window and have a wall or something next to you to bounce sound off of.
Just don't lug it up a hill, this can happen in 3rd at 40 mph too, I have had to down shift to 2nd before. Gauges first.

Are you having surge? If not why use that? IF so, maybe the ported housing might be more money out the door but might pay off in the long run for surge control. IIRC, the WW does move less air.

Jhand124, if you have no cat and the walker mufferthis will serve you well. John Woods put this on his dyno and said it is the same as 4" exhaust with just a chiped truck,"but" you can be towing up a hill and not even know it at low rpm's and the EGT will raise real quick. Gauges for this is a must! If your trailer is super light probably not an issue, but travel trailer or toyhauler be really careful. Your pcm will probably defuel and blow black smoke but you don't want this to happen more then once, that is even lucky. Blow the money on safty asap it could save your motor and real procket bock.

Glad you got the exhaust first. I did the same. About to buy the DP. I was always told. Make sure you have sufficient air in and out before you throw any kind of chip or tuner on. And I really do agree.
