Hi there, i have been a member of advrider for some years and also viewing this forum too[with a friend in the bmw section]. I have purchased a gpr 2 into 1 full system for my katoom and have a neduro link pipe and wings ti exhausts for sale both in used but good condition if any uk guys want to upgrade their 950/990. £400 for both parts or split £100 for the link pipe/ £300 for the cans.
