Hi Gentlemen, I will be swapping out my 71 Cuda's exhaust system and want some feedback / recommendation on what I am thinking. This car does not see any track time, but I also do not want to be embarrassed by some Mustang street rat. I am looking for a performance boost and a more aggressive sound. Currently there is no drone while cruising and I want to keep it that way.
3 Questions: Header size? Exhaust size? (going with TTI on both) Which Dynomax Muffler?
440, 0.30 over 452 heads, 3 angle valve job, no porting, stock valvetrain 9.7:1 600 CFM Edelbrock Performer Carb RPM Performer Dual Plane SpeedPro Cam #CS-1148 224/224 duration @ .050 lift, 455 int/455 exh, 112 C/L Factory HP manifolds Dual 2 ¼ exhaust all the way, Dynomax Ultraflows, H-Pipe, factory 1 ¾” Cuda tips 727 auto trans, TCI Breakaway converter 8 ¾ rear, 355 gears
Thinking of 1 ¾ headers, 2.5 exhaust, 2 ½ Dynomax Ultraflows, X-Pipe, 2 ½ Cuda tips.
Your thoughts?
What about keeping the current exhaust, but going with the headers and swapping the tips to a larger size?
What if I had the Edelbrock Performer RPM Heads? Would that change your recommendation?
Thanks All!

I would step up to three inch pipes and muffs all the way from the headers, same on the tips I would also look at aquiring a Holley 950 HP, if you want to make sure you can whup up on all the locals rustangs, not the real fast oone though
