I am buying a 94 gsr and it currently has a Tenzo R medallion style muffler with 2 1/4" mandrel bent piping all the way back. Would it be worth the money to get rid of this and buy a Tanabe racing medallion exhuast? Would I gain anything performance wise? Thanks

 

Minimal gains unless the bottom of the exhaust is damaged.

Maybe 1 hp.

 

i'd be more concerned about not loosing hp with these exhaust.. and if you're going to have gains, it would be minimal..
