I've got a 4 stroke with a very loud cobra exhaust. Rather than buy an expensive quiet exhaust I was thinking of using the spark arrestor insert from a stock blaster silencer. Would this work (I'm pretty sure I wouldn't have any problems getting it to fit)? If any one has this insert in decent shape and also has the gasket please e-mail me and let me know, I'm am interested in purchasing if possible. Thanks

 

there are no gaskets or o-rings, make sure to re-jet or at least do a plug chop when you install it.

 

hey what model cobra exhaust do you have?
