does any of the sponsers sell a bolt on over the axle true dual. if so what ones or if not where can i find a places that does it. none of the exhaust shops around me wanna do it they say it wont work and there isnt enough room. basically they are too lazy and dont feel like doing it so i dont mess with any of them so if anyone couldhelp me out i would be greatful.

 

Bassani makes one, but its for cars with stock manifolds. it can be tweaked though and used on longtubes
