I´m waiting my thunderheader system 2 in 1 with a falsee pipe on the left for my ´07 RKC.

But I want to know if someone have this configuration. Does this system comes with baffles or they come right open???

I want to obtain the loudest set up.

Please help me with your opinions.


Thanks.

 

The baffle is built inside the pipe/muffler..... I've heard there are ways to make them louder by bending the fines/ baffles but I also heard that it will kill the performance also. The Thunderheader is pretty darn loud I think you'll be happy with them. If not I guess you'll just have to pump up that engine. Mine is alot louder/throuteir than a stock HD with a 2-1 Thunderheader.

 

I,m useing 2in1 . When I had her tuned with the sert the tuner bent a tab over to smooth out the torque curve , kinda of loud when I gouge it and drop the throttle. It has a nice deep steady rumbeing sound.no popping.
