That set up looks easy enough...
Do you have a H pipe or X pipe

 

Neither, I have true duals through a split chamber muffler.

"X" pipe exhaust setup

 

sure..but i cant answer it lol... I dont realy know much about exhaust set ups. So im kinda learning alittle as i go right now. SO a,ll this is very helpfull to me.

 

Maybe hes worried about one exhaust pipe being longer than the other and he's trying to make it more efficient by creating a scavenging effect from the cross pipe? lol Its like fluid dynamics only with more variables Honestly though for a semi stock application I dont think you will ever see the gains from it.

Btw kinda off topic, but I just took my Harley's exhaust system from a equalizer piped system to a non-equalizer. After research I found the difference wasnt too noticeable but the sound was better... I didnt notice much power loss, a tad but it wasnt anything that the tuning didnt take care of but the sound is pretty badass Its alittle more "aggressive"

 

Well, I won't steal Eric's thunder but the basis of the "H" pipe is to create higher torque while the "X" pipe is designed to provide top end horsepower.

 

hmm thats a hard decision

 

yeah i've been thinking when i get home to replace the cats with high flow cats and make it true dual pipes and still come out where it does now in front of the passenger rear tire!
