Generation III External Engine - need help exhaust too loud

I have pacesetter let into tsp ory into I think all loud mouth 1. This set up is way too loud, what can I put in instead of the slp lm1 bullet? I want to keep my slp set up just put a quieter muffler. Any ideas ?

I run magnaflow and a cutout so I have best of both worlds, maybe look into something like that.

I have the same set up except mines the TSP Rumbler. I'm about to take out the Dynomax and throw in a Magnaflow bullet or Borla XR-1. Haven't decided yet. But either of those will really quiet it down compared to the SLP LM1.

borla with a cut out

I have a set of high flow cats that I just took off if your interested. They will quiet it down a decent amount.

IMO, your best bet is a Magnaflow #12867 (5"dia., 14" case), but you will have to clearance the I-pipe area if you want to tuck it up good so you don't lose any ground clearance. You could go with a Magnaflow #14419 (4"dia.,14" case), it'll fit in the I pipe better with more clearance, but it won't be nearly as effective as the #12867 will.
Both are under $95 ea..
