I'm looking into a true dual setup on my 5.4l 2003 f150. The system would be true duals with 2 Twister mufflers (one on each pipe) and a side exit before the rear wheel. The pipes would all be 2.5". I want to know how loud this will be and if I'll lose any power from this. I dont feel like I'll lose power with the 4 cats still there and the 2.5" pipe, but then again I'm not an expert with exhaust. Or does anyone recommend using an x or y pipe.

 

2.25" and x pipe

 

nice truck, why would you exit your exhaust in front of the rear wheels? looks or sound ? your rims will always be dirty, you'll regret it. to each his own i guess. Ford tried that when they first introduced that body style and then they went back to placing the exhaust behind the wheel. to many complaints about it and to many wheel replacements because it eats away at the alumumin and chrome finish.( if you don't clean them on a regular basis) this is just my useless 2 cents. it's your truck.

 

I dont know if you noticed but i already have a side exit exhaust before the rear wheels and i love it. I think it looks awesome with the truck and isnt as boring as every other truck with their duals out the back, but thats just my opinion. I havent really had any problems keeping my wheels clean and i get no buildup anywhere from it.

 

if you like it that's what counts. i was just curious.
