Just finished the install on otherwise stock exhaust. I had the muffler out already so I used 80 grit sandpaper to sand all joints smooth. Assembled complete, without tightening and was surprised when it all came together- the pipes weren't bent perfectly but eventually they fit. Snugged everything evenly all round until tight. There's a very slight leak on either side due to the slots cut into each bypass pipe and the failure of the supplied clamps to cover them completely but I can't hear any noise from them.
After 3 days of driving, the results are significant. The sound is deeper and slightly louder-perfect for me! For the little money spent, I feel very happy with the outcome. Time will tell if the poor fit causes any damage- I don't expect it too though.
