Default 2.5" or 3" exhaust?!

306 / C4 combo, going to be sprayed...

Picking up Headers from Gator this Friday, and I'm not sure on the size of the collectors on them (Gator? StangItMan?) - but I was wondering what you guys thought / suggested for the combo: 2.5" or 3" exhaust? I think I'm going to run MAC Pro-Chamber and MAC Pro-Dumps.



Mmmm, once I get the exhaust squared away, I'll be almost done sourcing the "expensive" parts left in the build!

Thanks,

If your goal is only 400 I would stick with 2.5

On the motor, car will be sprayed with 150-200hp shot. Still stick with the 2.5" ?? I figured 3" definitely.

I am running the same exhaust. Long tubes to the MAC prochamber and MAC dumps...and i love the sounds. The black heat coating or whatever has lasted very well.
