I have the Borla stingers and IMO, they sound deeper, richer, and throatier than the SLP's based on that sound clip. At one time on this forum, someone had a clip comparing the Flowmasters to the Borla stingers. Most people liked the Borla's. Unfortunately, you never really know until you buy one and install it whether you'll like it or not. Ideally, you could find a late model mustang gathering whose participants had different exhaust systems you could compare. Maybe some members of a local MCA club could help. Good luck.

 

Any annoying drone with the borlas?

 

I have the Corsas and have been very pleased. Their website has several soundclips that are accurate. I also added Corsa's xpipe (leaving the cats alone). In my opinion this made the car quieter. There is no drone or racket from this exhaust. It doesn't sound very loud below 3000rpm, but then will open up substainally. The look of the 4 inch tips is extremely sharp! The car does accelerate and decelerate smoother than with the stock set up.
The only thing I would not have done is add the x pipe to my exhaust. Bought the Corsa on ebay for 515.00. good luck.

 

I have Summit racing's muffs, They sound great, rumble a little at low rpm, good tone, not too loud as to draw too much attention, a definite improvement over stock, and best of all only $190 a pair

 

I love my CORSAs

 

IMO the FR Borla Stingers are the bomb, I love the way my stang sounds!!! The drone is not that bad, its extremely tolerable!!!!

 

I rented the GT-H , and I must say thats a great sound! I believe they are the oval FRPP mufflers. No resonance, sounds great at WOT, just enough, not obnoxious!

They're gonna go in my GT!
