Exhaust question

My 72 K5 has a 5.7L V8 out of a 99' Tahoe. I am currently running a 2-1/4" dual exhaust with Flowmaster Hush Power mufflers. Is set up enough or would I gain some power by switching to a 2.5" or a 3" dual set up? It also had Hedman headers. It drives good but just kinda feels like its lacking a little bit. Thanks

Re: Exhaust question

the exhaust size is perfect. you might feel like it's lacking because at best you only have about 250hp
