Okay, more information.

I'm not worried about tight fit, this is exiting out the side. It will be a one-piece system, just like i had on my 72 Charger, only smaller. That was a very handy system actually... undo collectors and the two bolts and slide it out.

I'll be buying some pretty slick mufflers. They'll flow. My X-pipe perfectly imitates the Dr. Gas design, so i know its good (bad X-pipe designs can do more harm than good, and kill the sound).

I'll be seeing 350-400HP right off the bat. And maybe upwards ov 450-470 with the next build. I have no plans to ever see above 500HP.

I also just realized that both the X-pipes i have are 2.5". I thought i had one 3". I might have just decided. Hmmm... I do like the sound ov 3" though. My Charger sounded awesome... even with a complete junk 440. Maybe a 2.5" system with 3" past the mufflers...
