To reduce the loud crack in the exhaust note I made a reducer and inserted it at the clamp end.
The reducer is a tight fit and you push them in from the clamp end I made mine with an opening of 30mm,this reduces the overall loudness and cracking note and leaves you with a very deep rumble ,it also improves the back pressure which in turn improved the performance a little.Just do the same with both pipes and you can even experiment with smaller diamanters if you like.It worked for me and was simple ,then if you want it loud at a later date ,you just pull the reducers out again.
Cheers
