Those are race mufflers a total of 4 9 inch race mufflers. It cost me about $3500 to make it total and that includes Kemira 100 cel cats, in the normal position. I got the mufflers from an old fabspeed gen 1 exhaust. Then I used the turns from that exhaust and cut out the original 18 inch ugly mufflers and installed 2 race mufflers per pipe with the H pipe in between. It really works. I sold my old fabspeed straight pipes with 200 cell hiflow cats and built this. I did not loose top end and gained in the low and mid range. It is about 30% quieter than with the straight pipes. Still a little loud on cold start but once warmed up, it is perfect. I may eventually get a full quiet exhaust when I get tired of making so much noise. but the sound is intoxicating

 

im running a custom full 3 in setup and its loud but has NO drone and sound great !!!my neighbors dont like me to much when i roll in at 2-3 am from work , my one nieghbor is weekend warrior has a loud a$$ rattle box of a harley that he revs and likes make noise early in am so i return the favor by making his windows rattle.

 

Great video clip. Thanks for sharing. My setup is pretty load as well.
