all those # are very confusing to me
can someone just tell me what's the exact numbers i need to look for when buying a magna flow muffler?

thank you!!!

 

Inlet is the where the piping from the exhaust goes into the muffler canister. Outlet is basically the diameter of the TIP(s) on the muffler canister where the gas come out of into the atmosphere.

Inlet you want basically a 2.5". Stock is around 2.25". 2.5" is good cause then you can get a mandrel bent 2.5" Bpipe and get a bit more performance out of it on the top end and be ready to boost.
