i'd get thermal and call it a day

 

Thermal is about $500 for the catback system. I don't want to spend that kind of money, and I haven't heard the Thermal so I wouldn't want to pay for it w/o knowing what it sounds like. I heard the hayame and fell in love w/it. I was thinking today though that I should get the Type7 instead of the EXT cause who knows how the EXT sounds, it was the Type7 I heard.

 

so whould a muffler sound higher or lower with factory piping? and again is factory piping mandrel or crush bend?

thanks

 

I can't answer that to be honest, never compared. factory is crush bent.
