i remember a while ago my dads friend had a doom buggy and it was loud. i remember him buying something that sort of looked like a fence that he could stick in the exhaust to quiet it down. is there anything like this avaliable?

 

If you have a N1, or just a 4 inch tip, you could probally use a Apex N1 silencer insert. www.rx7store.net under "exhaust", and then "apex". $45

 

nope tips are 2 1/2 outlet.

 

anyone ever use glasspacks successfully? is there like a high high temperature glasspacks avaliable or something similar to them.
