i have the roush side exit kit right now and i know its a crappy design for hp its robbing it i am sure.... i have the side exit side skirts so therefore i have to keep the tips there so i am thinking of coming straight off the h-pipe with a bullit style muffler ( the ones that looks like resonator tubes) ad then turning to the side just like that. do you think there will be any real hp gain or will it just be louder and ill think i gained hp like hondas guys???? right now the exhaust comes off the h pipe goes back to muffler and then comes out and all the way back up to turn out the sides its alot of useless pipe so i do forsee a hp gain but who knows maybe you guys do....

You probably wont gain any hp. You just think you will have gained HP cause it is louder.

Its tough to say man... it seems like you are pushing an insane amount of power... have you got it dyno tuned yet?

i don't think the length of piping will effect HP that much, but if you wanna change it up, i'm sure someone or some muffler place will custom bend you some pipes... but DEF. get it dynoed...

yes it was tuned before the forged bottom end on only 10psi of boost and made 406 without my intercooler, cams , methanol , and now it should see and extra 6 or more psi im just trying to do everything now while im putting the car back together ..... i have this stuff sitting around 2 bullit mufflers and then 2 90's it would be simple for me and my buddy to do right now ...i am not looking for louder or better sound just hopefully more power
