How to decat?!

Just unbolt the first and second cat and put the decats in their place. Restrictor ring in the middle of the two decat pipes. The top bolts on the first decat can be tricky though you may need to heat them to get them off.

 

Is it really that straight forward? And when you say the ring goes in the middle do you mean side-by-side with the 1st decat 2nd decat or between two bits of pipe? Cheers buddy

You will need a 12" extension for your socket set to reach the top 3 bolts. Two of them you can get to ok but with one of them you will need a knuckle attachment to get it at an angle. I soaked the 3 bolts the night before in wd30 and they came off ok with patience, but I did round one off putting it back on so be careful.
