Quiet Muffler

[M5rokit]

I have a 325 ITR with a KromarKraft exhaust system that is making way too much noise at LRP. I've put on the trap with about 11 discs but it is really hurting the engine.
Does anyone out there have advice on a muffler to use that would drop my Db level? I know this depends on header,etc but I need to start somewhere.

Get in touch with Cameron at Conover Motor Sports. He did a straight-through custom deal for my Golf that I *thought* was going to be loud but is REALLY nice. For what it's worth, I HATE supertrap mufflers, going back to the late '70s...

I had issues with sound on the 240sx until I used a Flowmaster Delta series. With the muffler, I used a turn down at the exhaust exit point, and I didn't have any issue after that at any of the tracks I raced at.

possible quick fix.......... leave in 12 discs and replace end cap with the open one.......

I've had very good luck with the Borla 'Sportsman' XR-1 series racing muffler on my H-prod.
I am typically in the low 90's for sound.

you can call active autowerks in miami [305-233-9300]ask for karl he's the owner,
he has a great system .it make just as much power as the kromakraft.it has 2 silencer for quiet tracks and you can remove 1 for 95 db tracks.
i did a lot of dyno work with them testing new stuff on carlos G car. i also believe bimmerworld is selling his exhaust system.
i hope this help!!
