New guy trying to get the "best of" exhaust posts

Guys,

I'm sold on the Mandrel bent & the Dynomax Ultra Flo, just need to find the right combo of pipes. I am going to install the Doug's headers and already have the stainless tips in 2.5", for the rear ('68 Dart GTS).

Neither the Summit or Jegs (muffler-less) set ups offer an "H" pipe (that I can see), so do I need to use the Pypes "X" system if I want the cross-flow or L/R banks balanced?

TTI just seems too high priced...but maybe I should bite that bullet(?)

It also looks like they'll all need to be cut, if I want the stock tips on there...

Please share your thoughts and experiences.....

I swear, if I have to punch my Make/Model in one more searchy....

Thanks,

Pete
