It looks like they layed the pipes on top of each other and ran them over with an 18 wheeler. Do yourself a favor and if you do the y-pipe do the whole thing because the bends in the stock pipe coming off the manifolds is also extremely squished in the bends.

I think I'm going to buy one now too. Did you do 2, 2.5" pipes in and a single 3" out?

Yeah but at the moment I'm choking it back down after the cat back to the stock sized pipe. That is next on the list for exhaust is the cat-back in 3 inch with maybe a magnaflow or spintech on there exiting behind the rear tire. Right now I just have a Flowsound muffler on there. It came with the truck. It sounds great but drones at around 57 mph and I feel like it is leaving some performance on the table......

Thanks for the info guys. My plan is to run 2.5" or 2.25" pipes from both manifolds on my '02 4.7 Dakota into this Magnaflow Y pipe then a single 3" Magnaflow muffler. I will remove the stock resonator and the rest of the stock exhaust completely.

From everything that I've read on the 4.7 performance, 2 2.5" or 2.25" primaries from the manifolds into a single 3" exhaust works wonders with the HO cams, HO intake manifold, 70mm TB, 180 degree thermostat, cold air intake, clutch fan delete, and a tuner (either SCT or Superchips). There is a guy with a club cab 4.7 5 spd Dakota running high 13's with similar mods here:

You have to read more into what he has done. He has 212x cam but w/e on that part. He has slicks and skinnies up front. He also took the belt off of the motor, yeah you read that right. Also has a 5 speed which gives him quite a bit of time if he can shift decently. I will be close to that soon but I'm definitely gonna need a stall and slicks to get there.:rant:
