needed to know? I need to change my b-pipe on my 89 SE max, was thinking about going to warpspeed to get their mandrel bent b-pipe which should help with hp and exhaust getting out of the engine along with reducing the bends in the b-pipe which rob u of hp. But I already have the mandrel bent y-pipe from warpseed already on the car, so how much more hp or benefit if any will i get out of installing a mandrel bent b-pipe? Let me know all!!! Thanks!!!

 

beats me, probably nit much in a vg.
