Whazza22 Posted March 12, 2013 Share Posted March 12, 2013 Hi all, I have a K1 exhaust fitted which sounds awesome!! The only problem I have is that the centre pipe gets wider (booster?) right where the brace goes across the underside of the car. This is causing the pipe to vibrate on the brace which is doing my head in! My local exhaust garage told me that I would have to have the booster part taken out and a new smaller pipe welded on. I don't really want to start messing with the pipe when really it shouldn't need modifying if its designed for the car. Has anyone else experienced this problem and if so, how did you sort it? Thanks Quote Link to comment Share on other sites More sharing options...
ioneabee Posted March 12, 2013 Share Posted March 12, 2013 (edited) japspeed - the word says it all (as I understand) most people have fitment issues !! Edited March 12, 2013 by ioneabee 1 Quote Link to comment Share on other sites More sharing options...
MITZ@CougarStore Posted March 12, 2013 Share Posted March 12, 2013 Common issue for it to be resting on the subframe with the K1, causes the system to resonate through the car... 1 Quote Link to comment Share on other sites More sharing options...
The Chubby Ninja Posted March 12, 2013 Share Posted March 12, 2013 Only everyone who has ever bought one. Alot of people put heatproof foam between the exhaust and the brace. It wont rattle for too long as itl probably fall apart pretty soon anyway lol 2 Quote Link to comment Share on other sites More sharing options...

Husky Posted March 12, 2013 Share Posted March 12, 2013 It's because the exhaust is cheap, badly made crap. It has been known not to fit for what? 5 years? The manufacturer have been made aware numerous times but they don't care because people buy them anyway. The company in china that spit them out must love it. Nothing changes as no one does the research before they buy. The money spent to fix a Japspeed could have been spent on a nice custom exhaust, etc etc. Sorry I'm sure someone will come along with a more helpful post than mine involving a big hammer soon.

rtbiscuit Posted March 12, 2013 Share Posted March 12, 2013 Ah the joys of crap speed. Biggest PoS on the market, doesn't actually sound good it just sounds loud. When you actually compare it to a well designed system its like comparing the philharmonic to a retard with a kazoo. Low grade steel, low grade welds, poorly designed and cheap. 3 Quote Link to comment Share on other sites More sharing options...
KyleR Posted March 13, 2013 Share Posted March 13, 2013 Chop it out and give it to a charity that accepts scrap metal and buy yourself a proper exhaust, plenty of decent budget options out there Quote Link to comment Share on other sites More sharing options...
Jmanji Posted March 21, 2013 Share Posted March 21, 2013 Phew lucky I read this thread, was gonna buy a k1, but not now!!! Thx Quote Link to comment Share on other sites More sharing options...
Voodoo Vix Posted March 21, 2013 Share Posted March 21, 2013 (edited) Going to throw a spanner in the works now; I have a K1 and have never had any issues, fitting or otherwise and its been on over 18 months, maybe i'm a lucky one lol Edited March 21, 2013 by Voodoo Vix Quote Link to comment Share on other sites More sharing options...
smudgedon Posted March 21, 2013 Share Posted March 21, 2013 My one fitted fine too, but when thriftyfifty took it off me he had issues Quote Link to comment Share on other sites More sharing options...
rabbitstew Posted March 21, 2013 Share Posted March 21, 2013 It can catch on that cross member. You can shim he cross member with a few washers, or slightlyly bend / flatten the pipe to clear - dont start bashing it too much else you`ll mess up the exhaust gas flow. For the money (around £150 second hand) the K1 isnt a bad system in my experience. Certainly very loud, but i thought mine sounded pretty good. Id be going for a scorpian or cobra system next time around though. Quote Link to comment Share on other sites More sharing options...
Olliecrx Posted March 21, 2013 Share Posted March 21, 2013 This might sound odd but has anyone ever blocked off one half of the y split at the rear boxes and effectively made one of these exhausts a single exit? Quote Link to comment Share on other sites More sharing options...
The Chubby Ninja Posted March 21, 2013 Share Posted March 21, 2013 Think this would look crap. It would look better if it came up at an angle for a single exit. Also theres the shape in the bumper for the second pipe that wouldnt look right Quote Link to comment Share on other sites More sharing options...
Olliecrx Posted March 21, 2013 Share Posted March 21, 2013 Yeah I wasn't sure about the angle it came out at. I had a kakimoto single on my s2000, the 2nd exhaust cutout isn't that obvious and generally doesn't look stupid. But the rear can needs to be angled Quote Link to comment Share on other sites More sharing options...
The Chubby Ninja Posted March 21, 2013 Share Posted March 21, 2013 Alot of people on here hate the single exit but i quite like it. If mine were turbod id definetly have a single exit. The s2000 would look sweet with one Quote Link to comment Share on other sites More sharing options...
Ricey Posted March 21, 2013 Share Posted March 21, 2013 The number 1 way to make your car sound like a chav nova......a K1. Hideous looking, hideous sounding, hideous quality, hideous fit. Hideous. Quote Link to comment Share on other sites More sharing options...
Ebized Posted March 21, 2013 Share Posted March 21, 2013 Over the 8 years this forum has been live we have heard on here about more fitment issues associated with the K1 than probably all the other aftermarket exhausts put together. Yes, they maybe cheap and loud which appeals to some, but we have also then seen how many owners have got frustrated by poor fitment, or after a relatively short period of time find they simply can't live with the noise and sell on. Enough said? Quote Link to comment Share on other sites More sharing options...
