  1. Hello folks, 
    I recently posted a video about some issues I've been having with my GT86 - 
     
    In that video I speak of a rattle that I've had for a good month or so now, it seems to happen around the 3000-3500 rpm mark, or rather when the vibration from the engine is a little higher than usual - it sounds like a part vibrating on metal, from the left underside of the car. I imagine it to be something like the exhaust vibrating on something and I originally thought it to be a nut vibrating somewhat, people have mentioned the rattles you get in the GT86, I have them too but this is a little different.  It seems to happen more so when the car is cold, but it does happen when it's warm too just not as often (it could be just as often but my music drowning it out)
    I spoke with the chap who's helped fit a fair few of my parts and he recommended to smack the backbox a little bit in case a baffle had worked its way loose, but given it's under the left hand side of the car I wouldn't be surprised if it was exhaust related (stock exhaust atm).
    Other people have cited it could be a mount, or a hanger for the exhaust. 
    Anyone had this issue before or something similar, any ideas as to what it could be?
    Thanks in advance folks
    Engine undertray maybe

  2. Thanks Sam, I've just tried playing with it a bit and had some limited success.
    I moved the exhaust and rubber guides as far right as I could, took it on a test drive and i got through the whole rev range in a couple of gears without any of the tin-can sound at all, but a couple of minutes later it was back. So I think the integrity of the exhaust is fine, and it is rattling against something when under load.
    It is right up against the heat-shield (touching it), is this normal? The heat shield doesn't seem to be lose. 
    My other thought is that the exhaust passes very close to this part of the chassis (image attached/below), the photo is looking towards front of the car. So if the exhaust is off to the left and then vibrating under acceleration then i may well be hearing it collide with the chassis.

    Thats close, too close i would say and definitely could be your noise, you could use jubilee clips on the exhaust hangers to create a gap so the rubbers cant move may hold it away from the subframe there

  3. Could be a heat shield, the catalytic converter cells rattling around inside its case because it’s detached or a loose bolt.

    Not much you can do without getting under the car. Unsafe unless you use jack stands or at least put a wheel under the sill, especially using the jack from the boot.

    I’d take it to a local Independent garage get it in the air and ask them if you can take a look. If their not busy good chance you won’t get charged.

  4. Gt86 decat pipe £100, takes out the second cat, no issues with mot or cel at this is after the exhaust sensors. Flanges and hanger in good condition, no cracks, welds in good condition, bit grubby but its a pipe under the car, doesnt need to be shiny.

  5. Drive them from stone cold today to the local tyre place to get some new tyres fitted. Braking performance from cold seems fine and there was no noise which I'd expected from a lot of the reviews I'd read. 
    225/45/17 AD08RS's fitted to the Konig's. I was concerned they'd be a bit too stretched as it's a 9" wheel but they are fine and look similar to the stretch of my 225/40/18 PS4's on my 8" wide wheels

    Ad08rs are a very wide tyre
