Hondavti Posted August 13, 2015 Share Posted August 13, 2015 Hello peoples need some advice on which exhaust gaskets i have to use on both ends of a genuine cat pipe on a mongoose exhaust system. The manifold and downpipe is standard but the decat, mid pipe and backbox is all mongoose. After the decat is a short collector pipe i think thats what its called. Basically im putting the original cat back on for mot as its been been parked up for 2 years and its coming back on the road and ive had it since 2003. Do i have to buy two dougnut gaskets, one three bolt triangular and a 2 bolt oval type gaskets?Im honda braindead as ive been stuck in a new ford galaxy for family use, good for economy and comfort but i just miss my MB6's VTEC THRILL.Appreciate some advice please?

spudley1988 Posted August 14, 2015 Share Posted August 14, 2015 it will be one doughnut gasket for the 2 bolt end and a triangle gasket for the 3 bolt end mate. Can get a kit with new bolts etc from motor factors if required. Got mine for around 12 quid. Quote Link to comment Share on other sites More sharing options...
Hondavti Posted August 16, 2015 Author Share Posted August 16, 2015 Thanks alot for your reply i tried to get the nuts loosened but looks like its going to have to go to a garage to get heated or drilled out. Quote Link to comment Share on other sites More sharing options...
KiNK43 Posted August 16, 2015 Share Posted August 16, 2015 Have a look should be able to see. Bare in mind oval gaskets are size specific.And just a tip I don't even bother trying to undo certain nuts now. Have some new ones ready. And cut the old ones off with a grinder or whatever.
