Calling Ramsing.... Calling Ramsing...... or rather Captain of the Black Pearl.....this question for you.
Ktteoh,
Beg him for a test drive. Sound wise I love it but then I only reliase how nice the exhaust sound when it was driven away from me for good. sigh....
Power wise, absolutely no idea. Do note that Speedworks didn't use their own stuff on the Black Pearl. They were HIOP header, REMUS mid section and HIOP muffler but all done by Speedworks so you got to check with Speedworks, what are they giving you. Their own HOTBITS item of other brand.
