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.

sorry i saw a $100+ price on borlas vs about $60 for RP's, didnt look at or compare polished. but the borlas & others may have slight differences in internal design to change the sound a bit, i still feel the straight throughs are similar sounding on a similar engine/car in my experience.

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.
