Brett350z Posted September 29, 2009 Posted September 29, 2009 Hi My new Japspeed K1 is arriving today, was going to get a garage to fit but am tempted to have a go myself. I will have access to a garage, axle stands and all tools but am debating whether there will be enough room for one and whether I will have any issues with the original bolts. Car is on a 53 plate. Can anyone who has fitted a K1 or infact any catback exhaust themselves give me any tips and basically best place to start etc. Would be grateful Thanks Brett Quote
srobrien Posted September 29, 2009 Posted September 29, 2009 I installed mine myself with some axle stands, word of warning though, the mid pipe bolts WILL have frozen up, you need to get a hand held blow torch or something to heat them up prior to removing. I snapped mine and ended up having to drive to the garage with no back box to have them drilled out. Once you have the old one off the K1 is a piece of p*ss to install. Oh but I would get a mate to help as it would be very awkward doing it yourself. R Quote
BulletMagnet Posted September 29, 2009 Posted September 29, 2009 Depending on age of the car, you may need airtools to remove the mid section from the Y-pipe. it's easier to get it up on a lift or have a trench to work in tho. My local garage took less than 30 mins to remove the old exhaust and fit the K1, just to give you an idea. Quote
IanS16 Posted September 29, 2009 Posted September 29, 2009 Me and nurrish had a right erm, laugh(?) trying to get my exhaust off. It took his old man with an angle grinder in the end As said previously, the K1 install is easy, its removing the old one thats a b*tch!! Good luck anyway Quote
BRO-T Posted September 29, 2009 Posted September 29, 2009 I thought about removing mine by myself, in the end drove it to my m8s garage. he had to use a blow torch on 3 of the nuts, even then they were stiff a job to get off!! After that my K1 was fitted under half hour!!! Quote
Brett350z Posted September 29, 2009 Author Posted September 29, 2009 Thanks for the replies, old man has a small heat torch and we've a pit in the garage so I hope things will run smoothly, just took delivery of the exhaust and very impressed, welds look fairly tidy. Have removed those wussy bungs aswell Will post a update later with how I get on, any tips on best place to start? Midpipe end or backbox? Loosen all bolts and remove or do one at a time?....

BulletMagnet Posted September 29, 2009 Posted September 29, 2009 I'd start from the backbox working my way to the y-pipe for removal and reverse for install Quote
Darren-B Posted September 29, 2009 Posted September 29, 2009 Id say get the mid pipe off 1st, to give you more room to swing the huge oem rear box around as the rubber grip things are a bugger Quote
Adriank Posted September 29, 2009 Posted September 29, 2009 I would get a garage to do it, for the few quid it costs, it saves you a LOT of messing about. Quote
Brett350z Posted September 30, 2009 Author Posted September 30, 2009 Old man didnt get in until late last night so we didnt give the exhuast a try. Local performance garage who I used to take my Type R too managed to slot me in this morning to fit the exhaust. Got a call just now saying they are having problems fitting it, strange I thought as they have done many 350z's before and no members on here have had problems with the K1. Just been down and the midpipe is catching heavly on the crossmember, pulling the flex's on the y-pipe badly. Its also catching on the rear anti-role bar and diff. Really disapointed as I expected it to fit no problems. Garage confirmed they couldnt spot a problem with the car. Luckly taking the standard exhaust off was no problem so ill get it put back on and pack up the K1. Garage are supplying pictures which I will post up later. So so gutted. This along with a 10 hour stint of uni in a bit is going to make my day Quote
Adriank Posted September 30, 2009 Posted September 30, 2009 This is a usual thing with Japspeed ones, they often foul on the cross members etc.. Most people just use some heatproof stuff to stop the rattle. this is the downside of buying cheap, you get lax tolerances! Quote
srobrien Posted September 30, 2009 Posted September 30, 2009 I had no problem at all with my japspeed exhaust, is your car a coupe or a roadster as i know the roadsters sometimes have clearance issues. Quote
mwalker56 Posted March 2, 2010 Posted March 2, 2010 This is a usual thing with Japspeed ones, they often foul on the cross members etc.. Most people just use some heatproof stuff to stop the rattle. this is the downside of buying cheap, you get lax tolerances! I have a slight rattle on mine, can anyone recommend some heat proof padding. Also thinking of dyno-matting the inside of the boot to reduce the cabin noise, has anyone done this before? Quote
98duffa Posted March 3, 2010 Posted March 3, 2010 just fitted k1 tonight i have the same issue got eveything to sit right after a few adjustments minus the downpipe that sits on the crossmember as soon as it is tightened. what type of heat proof padding can we fit under it Quote
98duffa Posted March 4, 2010 Posted March 4, 2010 think im going to heat up the downpipe tomorrow and hit the bottom more flat so will be like an arch shape that way giving the clearance of the cross member. whatya think Quote
Wookiee22 Posted March 4, 2010 Posted March 4, 2010 think im going to heat up the downpipe tomorrow and hit the bottom more flat so will be like an arch shape that way giving the clearance of the cross member. whatya think Are you not tempted to return it and request one that fits? Strikes me as a fairly drastic measure to have to take on a new bit of kit! Quote
98duffa Posted March 4, 2010 Posted March 4, 2010 its a common problem on the k1s. im just glad thats the only place it touches and not the diff etc Quote
andlid Posted March 4, 2010 Posted March 4, 2010 this is crazy, what are japspeed saying about these??? Quote
slew77 Posted March 4, 2010 Posted March 4, 2010 Mine fit like a glove, the only problem I had were the old bolts. I'd definitely get in touch with japspeed if I were you! Quote
billyokco Posted March 11, 2010 Posted March 11, 2010 just had mine fitted today & garage said it was a poor fit n is touchin in certain places, its ok but at certain revs really vibrates. did any1 find out what sort of padding can be used? Quote
chippychip123 Posted March 11, 2010 Posted March 11, 2010 I know it sounds a bit bodgey but i just undone the four bolts holding the front of the cross member up and spaced it away from the car and replaced the bolts with longer ones. Its cured the rattle Quote
98duffa Posted March 12, 2010 Posted March 12, 2010 took some heat shield padding from the underside of an engine cover off a diesel focus going to wrap it round the pipe and secure with exhaust bandage Quote
Neilp Posted March 12, 2010 Posted March 12, 2010 Mines sits squint in the bumper. Sounds the daddy though, thinkin about changing for scorpin though. Quote
cfoster Posted March 16, 2010 Posted March 16, 2010 Bit worried about all these dodgy fittings now!! My K1 arrived this morning as well as a Magen Y pipe, hoping that it fits ok :S Chris Quote
