thats fine, everyone has their own opinion & perception on things like this. but most guys will agree when it comes to mufflers, the engine combo & rest of the exhaust system make a huge difference in the sound of the muffler. a 320 hp olds vs a 400 LS would likely sound quite a bit different, different headers, cam, compression, bore/stroke etc between the 2 engines.
also i recall you recently saying how much you hate the race pros, even described them as "raspy" or glass pack sounding.... i have never heard them described that way nor do mine or any others ive heard sound anything remotely close to glass packs. must be a case of the engine/exhaust system differences & personal preference.
& the borlas probably have some internal differences in the packing etc, they are almost 2x the price of race pros... & the engine/car difference is a big factor here, your firebird with borlas has a low compression stock iron head 285hp 455 vs a 400hp LS on the race pros... of course they will not sound anywhere near the same & comparing the 2 is apples to watermelons. but im glad you like them & im sure they are a good muffler.
