Is there any advantages to having a 3” Y pipe that merges into a single 3” intermediate pipe vs a 2-1/2” Y pipe that merges into a single 3” intermediate pipe? Either size is going to be restricted from the 3" intermediate pipe so..
I’m leaning toward the 2-1/2” into the single 3” pipe to help with ground clearance.
whats your thoughts??

Dual 2.5" pipe supports around 500RWP...the real bottleneck is the 3" pipe.
This winter I am going to do a dual 2.5" into a 4" back setup.

Personally, I wouldn't reduce the pipe at all after the header flange. I'd rather scrape than compromise power or sound. If you're really worried about clearance, go with an oval pipe in the problem areas, then as big of an I pipe as you can to a cutout. If I could run 2-6" inch stacks with flappers out the roof of my car, I would.
