Has anyone got one of these on their octavia? My rear silencer is about shot and ive been thinking of buying/fabricating one of these for my 1.9 tdi.If anyone has one , are they hard to fit and do you have to cut the rear bumper for clearance?

Harry has one on his MKII

A search will bring it up....

To fit a dual exit onto the mk1 you will have to lose the rear towing eye and modify the body in that area, as it all gets in the way.

am I good to you or what?

I'd like a Mk4 R32 twin exhaust on my 4x4 but don't think it'll fit without a lot of work and probably having to lose the spare wheel well.

Thanks guys, looking at it ,I think the only way to have twin exit pipes at the rear, is to extend the tails from the oe silencer, one straight from the box and run the other one either around the back of the wheelwell and out to the drivers side, or try and run it between the rear valance and the wheelwell, but I dont think there would be enough room between the two to do this and id have to heatwrap the pipe to stop it melting the bumper.Then it could be finished off with a couple of chrome oval ends.I will try and make up a template using plastic water pipe and see if it is feasable.

I considered doing this some years ago, but decided as it wouldn't offer any 'extra' performance I wouldn't bother, in adition the flow would've been pants to say the least.

The only place to go would be the front side of the spare wheel well, the piping would have to be 1.5-2" max and then you would run into the fuel tank filler neck a place where you don't want too much heat - granted being a diesel heat will be a lot lower..... then you have the towing eye/support section as another obstruction....

Best of luck with this one mate! I think you will need it as space will be a real premium!!

I find this picture strangely arousing!!!! :p :p :p

Loving the little solenoid valve control (n/s pipe) to give it a straight though sound!!

Thanks Steve, ive removed the rear bumper today and had a look at the possibilities, and it can be done(I think). The left hand tailpipe is straight forward to do , but the rhs is a little trickier. The end of the curved tailpipe will have to be cut off, to enable some flexible stainless pipe to slide over and be welded on.Then a length of stainless exhaust pipe will run between the rear bumper and the wheel well and be wrapped in heatwrap and be attatched to the wheelwell with a U clamp.There will be an alloy heatshield between the pipe and the bumper just in case.Then another length of stainless flexi pipe on the other end, connected to a short length of rigid stainless pipe attatched to a rubber mounted hanger , and then attatch 2 chrome exhaust trims ,and bobs your uncle(in theory).It maybe necessary to remove the rear towing eye,and re-site it maybe , but I can live with that.. When I come to do it, will post some pics.

Look forward to seeing this

Why bother? Before allowing for wall effects (less on one big pipe than 2 small ones), a 3.5" ID pipe will flow 1.5x what a pair of 2" ID pipes will. Cancelling Pi on both sides gives us 1.75^2 = 3.06 vs 2 * 1^2 = 2.

ken put your feet up and relax buddy

Its only a truck engine lol,

I cant wait to see how this turns out.

Brave but if thats what he wants, I think it will look good.

Truck=Diesel coz I dint know how to spell it correctly
