Decided I'm going to gut the cat tomorrow.. its been bugging me for long enough so before i change my mind, going to take the headers off and attack this cat. Any one got any handy tips? should I cut a window in the box and re-weld or not necessary- just attack through the end?? Will post some pics before / during / after once finished
Hi Ian.. been searching all night! saw that one from Arthur and a few more but not many pics from this particular exhaust.. wondered if I had missed a good thread hidden somewhere but nothing even on youtube. Cheers anyway
"cut the back out drill the four spot welds and open up, remove cat, reweld plate and replace." ??? anyone expand???
Just been looking at your bike Gilesy... Really nice !! Exactly what id like to do with mine ! Im gonna keep an eye on this thread coz I'm interested to know if you feel the difference mate, and if so, hammers and chisels it is
cheers Blackness.. going to get stuck into it after supper.. been too nice a day to be in the garage! I'll record before / after to see if there is any difference in sound etc..
Just mash it out with a hammer and long sharp screwdriver, it's how I did mine on my RR7. The hardest part is making the initial hole through the honeycomb. Once that's done then it's a case of just chiselling round the hole chunks at a time. Remember to give the headers a good shake turned upside down, maybe even poke a flexible pipe down to make sure no lumps are hooked up inside the pipes anywhere. I think my bike sounds much better with the cat out and seems to have better throttle response too.
Well finally got round to gutting the cat last night. Wasn't as bad a job as I thought, just went for Derchef and Tom's "smash through the end" technique. Started off my making a hole with the drill in the middle of the honeycomb, then a big chisel and hammered the f**k out of it.. all gutted in about 30 mins.. going away to put the bike back together, will upload a before / after video of the sound later tonight
Should be interesting when its back together. I'd like to know how it sounds and runs, especially if you have a Remus can.
Nice one...it's not such a bad job to do is it...it's just the trepidation of making the first "incision" LOL I hope you saved the honeycomb !!...worth a few bob all the precious metals in it you know...
Before and after.. what a sound! so glad I did this.. sounds so roarty! Saved the honeycomb.. what to do with all that platinum! Scrappy? Trying to upload the video's now..
bugger.. can't figure out how to upload the video.. will try again in the morning! worth listening to..
Ok..no IT whiz but try this: Admittedly, I do rev the bike a little harder on the bike after I gutted it.. sounds awesome!
Absolutely. . Put race air filters in it over the winter so will get it back on the rolling road. Weather looking good over the next few days so I feel a blast coming on!
