Exhaust pipe adapter
I'd like to swap my mufflers but the brand I want to get only offers 2.5" diameter mufflers. My pipes are 2.25".
Would it be ok to use muffler/pipe adapter from 2.25 to 2.5 for the inlets and outlets? Would be a 1/4" larger muffler with stock size pipes make difference on anything?

Bottom line: I want to replace the whole system to a 2.5" when I'm ready to get the headers so It would be a 'temporary' thing without welding. I'd just clamp it then when I'll replace the whole thing for the same size I won't need to cut it from the 2.25 pipes.
Should be no problem at all. The only time you would need to worry is if you were restricting the exhaust and creating back pressure.


"The only dumb question is the one not asked"
Thanks. Basically the exhaust line would be the same except that quarter increase in the size of the muffler. I double checked the manufacturer and they said you can use their 2.5 mufflers with a 2.25 system. Probably .25 inch wouldn't hurt. The mufflers are from https://www.blackwidowexhaust.com/ (venom 250) if sy interested. There's a lots of sound samples on the site. Kinda throaty, crisp sound what I'm after.
