I've jusy fitted a Remus Y piece to my 1150GSA and the two front joints are blowing. I bought it second hand but it hadn't been used. The only clamps I had were the BMW ones, but the guage of the y piece was thinner than that of the pipes on the cat. I filed down the spacers in both clamps and even tried removing one but the joints still blow and the clamps cannot be tightened any more.
Any ideas would be appreciated thanks.
