Hi there I was wondering if you peeps could give me some helpful answers.

I just got my X-FORCE dump pipes today, spent pritty much all day getting to the turbos and taking them off to mount on the new dumps, but I’ve come across a problem. The dump pipe is touching the turbo inlet piping on turbo no.2, I was thinking at high temperatures would the inlet melt? I have tried to move the turbo as much as I could away from it but still pritty close, its still giving me a 1-2mm clearance. what’s my way around this?

thanks..

Mate maybe speak to the people that sold you the dumps see what they say.I think it should have more

clearance than that.A option rap the dumps in heat rap tape this will avoid burning any thing, they will glow

red hot after a few laps around a track.One thing I have found is that nothing is a bolt on fit you always

have to mod it to fit properly.Good luck

When i got my X force 3.5 inch system i had it installed by a reputable installer and the dumps and front pipe where not correctly made to measure, as in it was only 1 or 3mm away from the chassis rails and i would hit for sure. Also where the dumps bolt to the turbos because of the tight tolerances when trying to bolt the exhaust on there was alot of pressure on them which would mean with the bumps etc the gaskets would eventually leak gas out, everything was just to tight a fit. So they just cut and angled the front pipe a little to clear away from the chassis rails and that in turn made alot less tension on the exhaust system. Shit you dont want a flange leak its hard enough to do a exhaust dump pipe change as it is, that was the only problem i came across, i even rang up X force and they wouldnt agree but DID not disagree, i was easy to see, did that and have never had a problem with it and i have had it on now for 8 months and drag raced the crap out of my gtr and its still perfect with plenty of clearance.

      I've owned a few scooters over the years, a Vespa PX oil burner was my first scooter, followed by a few others, including a little 50cc BeeWee that I used as a barracks bike, and I've had a blast on all of them, they really are the cheapest for of city/suburb transport around The only issue with scooters in Australia is lots of people look down on them due to their size,  maybe they need a big bike to make up for something else where they are lacking, unlike Europe and Asia where every man an their dog owns one, and now that filtering is legal in NSW, local traffic is never a issue Not to say I haven't owned my share of big cc bikes over the years, but they were for more blasting through the hills or Hwy riding where it needed to sit on Hwy speeds Safety wise, I ride like everyone is always trying to kill me, everyone is running a red, or running stop/give way signs, or generally asleep at the wheel, which most people are duringtheir commute, I also ride really safe, and give myself, and everyone else enough room in case I need to pull some hasty evasive actions, I've done a few rider training days over the years, which has come in handy on more than a few occasions  As for mods, there's nothing really, and yes your right about aftermarket exhaust, all you get is loud and obnoxious noises from them, like every 250-300 cc you hear with a aftermarket muffler, in saying this I did put a rear muffler from a 125 Aprilla on one of my old 125 scooters, it was horrendous and no amount of full face helmet and ear plugs would dampen that noise As for coming from the Harley, and what a overpriced POS that was, I no longer do big rides as my poor old busted joints ache after about 1/2 an hour of riding, long cruises are so much more enjoyable now in a car, so a big bike would be pointless

      Oh wow, it's easy to forget how cheap these can be. Probably the cheapest way to travel. Though people in cars here tend to be morons and I would not feel very safe. Were scooters ever big in Australia? It used to be the thing growing up in Europe ~20 years ago. 50/70/125ccm Peugeot or Yamaha and some others. Utterly obnoxious Polini race exhausts. Kick stands that slant as much as possible. So loud. So much noise for really not moving very fast at all. But it felt cool at the time. Not sure where I'm going with this, but there is an aftermarket for mopeds! Though I'd have pictured you more for a Goldwing kind of guy after growing out of the Harley.

      As the MX5 isn't apparently "manly" enough, and I need something for runs to the local shops, and also take to my part time job at the salon, basically I can keep the MX5 away from car parks and stuff......like "flying lockers", I was wondering what I could buy to fix this issue LOL, I pick up a new Yamaha 125 Delight this arvo from Trooper Lu, basically a R1 that you can fit a slab of beer on between your feet, also, it was $29400 cheaper than a R1, so actually it's 2 x better than a R1

      Nah. H2S. H2S is "rotten egg gas", which is what is associated with no cat. SO2 is equally nasty, and if you've ever smelt it you'll know all about it. More of a choking, acid in the back of the throat sort of thing. But you can only smell it in a narrow range up to about 1ppm. Above that, it irritates your mucous membranes, but you don't smell it.
