Exhaust/Mufflers
#11
Magnaflow makes a 2.5" stainless system that is labeled as fitting 67-70 mustangs that a VMF member installed on his 123 vert and it fit without issue accept for adapting to his header collectors which any system will require. I think I posted pictures of it here a long time ago.

I made my own from 2.5" mandrel bends and welded it together and while tight it fits over the crossover plate.

There is a company that makes a custom crossover plate with a drop which provides extra room. I have posted about that previously as well.

I am supposed to be working right now or I would search and post the linksBig Grin

Also you shouldn't have any problems but in two and a half inches tunnel. I did two and a half through the tunnel and I have an aftermarket aluminum driveshaft which is a half an inch wider than stock.

I understand you have the Dynomax Super Turbos. I can't tell from your picture, but, did the mufflers fit up in the pocket where the OEM mufflers go?

If you are still running the cast iron headers going larger with the exhaust pipe will probably make little or no performance gain.
I just took a Pypes 2.5" dual system off of the 72 vert parts car I have. It was two weeks old when it got crashed. They had put the spacer between the plate and floor on the vert to clear the Pypes system. 1/2" piece of box tubing between floor and plate. I don't have a pic in the car I do not think. The car sounded good with them not real loud. This was on a 351 H code 3 speed.
My 73 vert has Dynomax I believe and it is too loud for sure. Too loud if you want to talk to someone in a vert top up or down.
If you ever saw the Roadkill guys doing their experiments with exhaust headers on TV you might be surprised. They would beat on the tubes and close them up and it had zero affect on the HP on the dyno, lol. Had to be drastic to make a difference. Google it might be on youtube. They did same with air cleaners also.
Picture of the system I took off the vert, like I say brand new and ceramic coated headers but for 2-V heads. Took it off in one piece jacked the rear springs down to get over housing.
