    Default 205 exhaust corrosion spots?

    hi guys im takeing my 205 gti in to get a road worthy some time next week, but ive noticed a leekind sound towards the front of the car. i cant look under the car because its very low and my ramps are taken by the 405 mi16. so im a bit stuck. hhahah

    i will have to take it into an exhaust shop so they can lift it and change it. but are there any common spots to get a leek? just so i know

    and how much should a new system cost?

    any suggestions for a good one?

    im also looking into getting a twin tip muffler as featured on pugmonkeys? 205.
    but a slightly smaller one may be in order. ford focus st/ xr5 turbo?

    cheers

    The Manifolds are notorious for cracking. They sometimes sheer the joining bolts and can leak from the flexible join ( the correct name eluding me right now ) They can easily be welded up ( the manifold that is ). Should not cost or take too much time/money

    I had a quote for around $100-150 to weld but the man wanted it with the head to make sure he welded them true. Purchase second hand one here instead.

    When mine cracked I was told because it was an old cast iron manifold that'd been through many thousands of heat cycles with a crack full of carbon deposits it would be near impossible to weld. I found a 405 replacement, based on recommendations from the brains trust.

    The knitted wire mesh/conical exhaust gasket might be leaking? They don't cost much.

    The crack in the manifold in mine was a visible line.

    The gaskets are like this

    Simply machine the face of the manifold flat after welding.
    Otherwise plenty of 205 Si and 405 nanifolds around that are uncracked.
