I own a 2001 mustang bullitt. I already have a upr o/r xpipe installed with an slp lm1 cat back. This however is way to loud. Im am looking into getting either the slp power-flow or the slp lm2. I still want to have that crackling sound but I want the car to be quite a bit quieter. I just want to know if anyone else has the same problem with the loudness of the lm1 with the xpipe or if anyone has the lm2 or power-flow and how those two sound with an o/r xpipe. Also will the slp power-flows still have the crackling sound?:shrug:
 
I have had all 3 SLP mufflers with and o/r x pipe.

LM1 = annoyingly loud. Does not sound good at all.

LM2(current setup) = a bit quiter than the 1s but a lot more tone to them. Sound really aggressive. Loud enough imo

PowerFlo = Sound really good. Not as loud as the 1s or 2s but have a nice deep tone to them.

When I had the powerflos, they were not loud enough for me so switched to the 2s. If you still want them loud, go with the 2s. You won't regret it.
 
to the OP you wouldnt happen to have a sound clip of your car would you?? I have he SLP LM1's with what i believe is SLPs catted xpipe (bought car from dealer with these installed) and i love the sound. But i want a O/R pipe
 
I have had Magnapacks, Borla, and Bassani. Bassani is the best mustang exhaust I have ever heard. Its awesome, fairly quiet at normal cruising but sweet at wot.

Worth every penny imo. For what its worth I wasnt too impressed with the magnapacks.

1 - Bassani
2 - Borla Stingers
3 - Magnapacks
