this looks great and is what I've been looking for. As far as muffler choices go I have looked at cherrybomb Vortex #88115 or the Elite #7553 there is also Thrush #17637 and #17553 Dynomax ultra-flo x muffler,
hopefully one of these might fit. I have found the Thrush for $30 online. These type mufflers could also negate the need for a cross over pipe depending on the internal design of the muffler. The H pipe would increase rigidity and stability of the system though. Maybe, bar stock could be used to reduce expense. Would it be possible to set-up a picture comparing a stock system versus your new system? In another question, I saw in another thread you mentioned a 3.8L engine, can you elaborate? Keep up the great work.
