a pikey set up atm but its working and there appears to be no leaks. the 2 pipes are exact same diameter which caused a little bit of a problem connecting them together. I just wanted to get it in place to try it out. rode about 100 miles today. I love this exhaust! Not really increasing punchiness but nice sound, can be quiet , can be loud, but really good on the freeway. i got up to record speed today - no shakes, no vibrations. brilliant. Got a really nice thump too. Think im just gonna weld the 2 pipes together at the join then heat wrap over the mess.
