Hey I am trying to quiet down my exhaust a little and am wondering if anyone knows a good place to get resonators. I have searched the net and have only found a few suppliers-none with what I am looking for (3" inlet and outlet and 3 1/2" or 4" total diameter). Thanks for any input/reccomendations.

 

Depending on what you want you could just get a 4" pipe and get two flanges that neck it down to 3" to fit your pipe now. If you want packing I dunno how to help.

 

You might posibly call a company that makes evo exhaust and see if you could puchase a resonator and then have it welded in.

RRE has what you need.

Perfect-thanks for the rre link.

 

ams sells the vibrant resonators used in their exhaust system. They're made of s.s., 12" of resonated area & kinda pricey, ~$75

summit sells a mild steel resonator, which is 18" long. I thin their dynomax pieces, ~$37

I saw some resonators @ rre, not sure if they're the ones mentioned above, but they're louved. I recomennd a perforated resonator like the 1st 2 i mentioned.

The louvered pieces will be quieter, but you'll give up a several hp for sure.
