I have a tanabe concept g exhaust system with a new mid pipe and a header and i'm trying to quiet it down with a silencer but the tip of the exhaust is just under 4 inches (100mm). Can anyone point me in the right direction to find the correct size silencer?

 

i dont think they make silencers for that exhaust because its already quiet due to the material inside and its designed to be quiet in the first place. you can probably make a custom one at a local shop or something but i dont know of any size that would fit it.

 

if the muffle ritself has holes where you can screw the silncer in cause any 4 inch silencer will work..or take off the header worse thing you can do

 

the header is giving you all the noise and rasp, i'd take that off and see if you like it better like that

 

yea your ruined the sound with a header
