jasonaz1 Posted October 12, 2014 Share Posted October 12, 2014 Just curious has anyone cut the cat/muffler off and welded in a turn down pipe?Just curious has to how extremely loud/awesome it is hahahaha or anyone start the bike up while doing the m4 exhaust and see how loud it was with video?(cause you have to cut the cat off the header to do the m4) https://www.youtube.com/user/jasonaz1fz07 Link to comment Share on other sites More sharing options...
Premium Member V8titanpwr Posted October 12, 2014 Premium Member Share Posted October 12, 2014 Judging from how loud the M4 is, a straight pipe would be straight torture for the rider and everyone within a 50 mile radius. 2 Keep the rubber side down and the shiny side up.

jonskelton10 Posted July 6, 2015 Share Posted July 6, 2015 I know this is an old thread but have a question would it be tolerable if you left the cat in with straight pipe? Maybe make a baffle for it Link to comment Share on other sites More sharing options...
Premium Member hobbs Posted July 6, 2015 Premium Member Share Posted July 6, 2015 Seems like it would basically be a slip on then. Everything went braap. Link to comment Share on other sites More sharing options...
Global Moderator sorkyah Posted July 7, 2015 Global Moderator Share Posted July 7, 2015 Hmm, maybe its time to just take the yoshi muffler off and run w/o it That sounds beastly ATGATT... ATTATT, two acronyms I live by. Link to comment Share on other sites More sharing options...
jonskelton10 Posted July 7, 2015 Share Posted July 7, 2015 Thats what I'm thinking for a lot cheaper too and u can make if look exactly how u want. The exhaust that look good are pretty pricey I found someone who will do a custom one that will keep cat and have the bend like the akropovic and slash cut exit pipe for $200 Link to comment Share on other sites More sharing options...
Premium Member hobbs Posted July 7, 2015 Premium Member Share Posted July 7, 2015 I think idling it will be reasonable, but it will still be outright loud on the throttle. Without the baffle, my delkevic slip on makes my inner ear tingle at wide open throttle. Not too bad with the baffle. Everything went braap.

christrix Posted August 6, 2015 Share Posted August 6, 2015 I did something a little different I bought the double down exhaust from Toce for the R6 cut the cat off and welded the flange from a stock R6 exhaust on to the collector. Then I installed the double down which has no baffles so it's pretty much straight piped and is super loud but it sounds great except when you decelerate there's a bit of backfiring from the loss of back pressure so I'm going to fabricate a baffle. Actually when I talked to Toce they said there were working on a baffle for the double down so I need to call them and check on that first. Best part about it though is it looks amazing on the bike. Best looking exhaust I've seen in my opinion. Link to comment Share on other sites More sharing options...
Beemer Posted August 6, 2015 Share Posted August 6, 2015 With my Aprocovic pipe the whole town thinks I'm some heathen. They hear me rollin' and they sneer, I wave, they smile and wave back. They're coming around. Beemer Link to comment Share on other sites More sharing options...

jayrexer Posted October 15, 2015 Share Posted October 15, 2015 What was the sizing on the piping if anyone knows? I would like to retro fit an older slip on to the bike if I can figure out the piping before hacking into it. I'll be sure to post pictures once I have it done though Link to comment Share on other sites More sharing options...
jayrexer Posted October 19, 2015 Share Posted October 19, 2015 I went ahead and actually did this today. I had an old Erion Racing pipe laying around. I cut it down to make a stubby pipe around the same size of the cat/pipe section. We repacked the muffler which is straight through. It took some welding, but the bike now sounds like nothing else on the street! Link to comment Share on other sites More sharing options...

jayrexer Posted October 24, 2015 Share Posted October 24, 2015 Here are some quick shots of the work on the pipe. We had to do some welding to get it done right, but sounds way better. Total investment was $70 for this exhaust install 1 Link to comment Share on other sites More sharing options...
