    Boris 1piece downpipe

    right!
    ive been faffin about with this for too long.
    my current exhaust which is a 2"diametre magnex system will Not mate up to the boris downpipe. the downpipe opening is simply too big for the magnex.

    so im looking for a new exhaust to fit but id like to stay away from a side exit if possible but wont count them out as i know they mate up ok, also not keen on the scorpion[knocking].

    so for all that have the boris downpipe fitted - what diametre systems have you got fitted? and how well do they mate up to the downpipe?

    im just trying to work out what options i have.

    I have a 2.5" powerflow that mate's up perfectly.

    tbh if you have forked out for the large downpipe,then you'd be wasting your time & money if you bought anything smaller than 2.5" for your exhaust.

    ditto, im running a AAS system, full 2.5",fits the downpipe, i would say go custom,not that expensive,mine was only £250,no knocks or bangs either,dont ask how as there's NO room above the rear axle

    Re: Boris 1piece downpipe

    yo guys , thought id wright on this thread instead of opening a new one..

    would there be a connector , gasket or reducer available to sort this out anywhere on the market ,ive searched ebay cant find anything ,dont realy know what im looking for.
    i need to connect my scorpian exhaust onto a Boris bms one piece down pipe and it very hard to mate up without it blowing like a whore, i think i need some kind of reducer untill i can put the sidey back on ..

    Re: Boris 1piece downpipe

    okmy original post has vanished... i guess when i got got cut off briefly it didnt make the boards!

    your best tou go to a place the makes up exhausts then they can work with your d/p and exhaust... and build somthing suitable.

    id imagine it would be hard for boris to make an adaptor as he has not got your exhaust infront of him etc... just a guess though as they all have their differences
