Can't say I've done it on a bike, but many years ago I decided I wanted to make a straight-through system for my Vauxhall 2300cc Viva.... worked for a Vauxhall main dealer at the time so I just helped myself to a nice selection of 2nd hand exhausts in the old exhaust skip
while I was fabricating it at home at the weekend, my old boy came outside to ask me what I was doing, when I told him he just shook his head and went back in the house....
Finished it off, proudly fired it up and went for a blast....
15 minutes later I was back home putting the old one back on......It was unbearable!!!!
Suppose my old fella knew best after all........
hope yours sounds better... it's just one of those things you have to get out of your system.....
