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. |

Pypes MVR-16S $95.97 https://www.summitracing.com/int/par...r16s/overview/ Borla ProXS 40359 $96.99 https://www.summitracing.com/int/parts/bor-40359 Barely a $2 difference. Flowmasters SOUND like Flowmasters, whether on a stock 302 or a wild big block. The cadence of the exhaust will change of course, but the overall "sound" will still be quite similar. I had Flowmasters on the Cutlass when it still had the 455 Olds, and it sounded VERY much like the 455 Pontiac in my T/A clone when it had the Flowmasters (before installing the new exhaust/Borlas). I had the large case Georlichs on my low-11 469" '67 Firebird, and another set on my 427" SBF wagon - there was a different lope to the exhaust, but the overall sound while cruising or at WOT was pretty much the same.

my reply was to you saying your borlas dont sound similar to race pros, yet the borlas are on a totally different engine/car than the RP's, so it wasnt a fair or equal comparison. as long as you like them on your car is all that matters for you. some, including myself like the race pros & ultraflos, but on a different car they might not like one or the other. all comes down to the application they are used on & personal preference.
