SLP Dual Dual flow

Possibly thinking about getting rid of the Slp Dual Dual. Its a great muffler and like the sound, but would like something that flows really well with out the noise. Any suggestions?

Keep the dual/dual. It is one of the best flowing mufflers out there.

There's really nothing that's going to flow better and not be much louder. Only options are true duals or maybe the SLP loudmouth, and they will be louder.

I vote get a cutout installed; best flow when you need it, quiet when you don't.

I agree. Like mentioned already, the dual/dual flows very well.

Negative, they sure don't. Classifieds are it for the dual/dual.

SLP Dual dual vs 2OTL - which one sounds better?
Is the 2OTL made anymore either?

If you want to quiet down while keeping good flow, my only guess would be a Magnaflow muffler, they're supposed to flow good while being rather quiet. Not sure which models though...

2OTL is imo the best sounding exhaust for our cars. Like the dual/dual i do not believe it is produced any longer.

2OTL is slightly louder than a Magnaflow all over. IMO you can't go wrong with the dual/dual or 2OTL. With my H/C 98 and a 2OTL I can have a lot of fun on the street without attracting unwanted attention from the police or pissing off my neighbors in my sub division when I go to work at 4am. Ten years ago I wouldn't have given a crap about those last two but when you get older you kind of want to quiet things down alittle.
