Exhaust  |  Home

Well - no matter how much I love the rear dom - had to do something about that insanely loud noise - so went from probably one of the loudest to probably one of the quietest pipes.....

....And I must say I love the Mielke. The sound is a quiet, thunderous roar - which I absolutely can't get enough of!!

Dare I say it but the dom was almost embarrassingly loud but with this thing I could listen to it all day.

No cage melt issues or awkward fittings. Body can come off with no probs with pipe intact, enough clearance all round, (light pods, body, gear cover etc) subject to a new bracket (detail below). Aesthetics are cool - balanced handling and good  power all through the range.

If mounting the pipe with the wire bracket that comes with the Mielke, apart from the lack of robustness of the part, be aware that the pipe may be close to, or even touch the body,  resulting in localised melting of the lexan body.

An easily fabricated bracket from an aluminium angle (eg. 1.5" x 1.5") is highly recommended – it will hold the pipe clear of the body as well as firmer in a roll / impact situation.

Rubber bushings or some diy silicone washers (fuel tube) at the bracket screw position  will form a neat finish and assist with damping vibrations at the pipe connection (penultimate pic).

The bracket modification was originally posted by Lunatik Engineering on the hpibajaforum  a while ago and repeated in the post link below.

Even with the bracket modification, the pipe still lies close enough to the body to give a good measure of protection in a roll over (subject to terrain, of course), particularly when compared with some other side pipes. Probably a wise thing being made from relatively easily dented aluminium. Nevertheless side collisions are often inevitable and all pipes will be at risk to some degree or other.

The plastic type connector (on which the two jubilee clips fit) was replaced with some black (poly reinforced) silicone tube which will give an improvement over the stiff connection made with the stock connector and some flexibility in a bad smash or roll.

A 55mm length of19mm ID black silicone tube (4mm wall and 27mm overall) should be appropriate (though a  max straight length of 110mmm can be accommodated)

New jubilee clips will be required - 22-30mm size, as the ones that come with the pipe will probably be a bit on the small size for the new tube).

Having said this - the 19mm is a good tight fit and therefore one clip fitted around the header pipe side should suffice – this will also prevent any vibration marks from occurring on the top the gear cover (particularly relevant if a billet gear cover is installed) and make for easy removal of the pipe during maintenance.

Alternatively two heavy duty cable ties can be used – jubilee clips can be tightened too much resulting in deformed pipe ends, resulting in exhaust residue leakage.

One of the the good things about the Mielke is that it is very easy to remove and install at the joint with the header pipe.

This makes for quick and easy maintenance without exposing the exhaust port directly - simply plug / tape up the header pipe joint end during maintenance.

The silicone hose can be left in place, attached to the main pipe, with the cable tie at the header/engine side cut. After first removing the bracket connection screw, the main pipe can then be carefully twisted off with the hose intact.
