Muffler Inlet...2.5" or 3"?
I'm looking at buying an aerochamber muffler, SI/DO, but it only comes in a 2.5" inlet. Are there any drawbacks of going with a 2.5" inlet, instead of 3"? Any help is appreciated! This is for an '05 5.3.

They do make that muffler, I recently put one on a friends truck.
Single in 3" and dual out 2.5"
They offer two different models based on length
22" long case 21701HKR
14" long case 21518HKR
