I've run 3" in mine, all the way out the back, and had it on my 306 for a year before I bored and stroked the engine (getting ready for it!). Honestly when I went from 2.5" to 3" on the 306, I didn't notice any difference, up or down in power/torque, but the noise level did go up. The 3" tail pipes are tight....

Haha 3" on that stroker will sound like you have a monster under the hood. I cant wait till you get it goin and put a video up. Im pulling for ya.
I had a 3/4 ton gmc with a cammed out 350 edelbrock performer heads / intake with a 800 cfm 4bbl carb 3" full exhaust . I pulled some big *** trees out of the woods with it with minimal effort. The sound was amazing , and when I idled through a parking lot car alarms would sound off ....

My question isn't so much about whether or not it will hurt performance (though I think the argument has some merit), but more about if it's worth the trouble on anything short of a NASCAR motor.
I do remember reading some stuff about how exhaust gases contract as they cool in the pipe, thus loosing velocity, so in some applications you're better off to reduce your pipe sizes down in stages the further you get away from the headers. The intent being to maintain that velocity and increase scavenging. Again... This was geared toward race car type of stuff.
If nothing else, on a street car, I wouldn't go through the hassle of fitting up 3" TAIL PIPES. Turn it down in front of the axle or go with the regular old 2.5" tails.

I have been running 3in dumps for years now I am moving up to a 3.5 down pipe into a 3in x just cuz I want duals dumps LOL but I may just move over to a single 3.5 pipe so it sounds like a UPS truck. LOL no really just so it is easier to work with just not sure where I am gone to put it under the car. it is freaking huge. The 3.5 down pipe did come by the stock steering shaft more room over there then I thought.
Scavenging we don't want any of that **** I would just dump it under the hood if it would not make so much heat LOL. I run the Morose spiral flow right now but I need to do a back pressure check again if it is to high with the new down pipe. If it is I guess I am gone with a race bullet muffles our car is quiet now due to the turbo hushing things down even with the 3in. which I like much better then all the noise and drone. Getting old here. But the big plus is the sleeper effect it has it cant be fast it is not loud. till they hear it spool then they know they been had LOLLOLLOL..Love it
