well guys i need your help
after last yrs track days i was sick of being black flagged for noise
so i gone out and got me a magnex for the 3door
not after cutting a shutting i need to either run the single box or get another box to come out the other side the drivers side aswell
these are only 3 inch pipes not silly big bore things
i also have a screemer pipe running over the rear beam and out the back aswell
not out the bumper thow
so help me lads and lasses would all will be part of the 3door development

 

main question is (as i dont know about these things ) will adding a second box effect power?

 

To be honest mate i think having 2 exhaust will look silly, get one of the photoshop people to do it for you, that way ya can see what it will look like.
HTH

 

not your average 3 door tho so I don't think twin pipes will look to wierd.
If it keeps you within noise regs then it is worth it

 

i don't like the idea of twin pipes - on a vee engine yes, but not a cossie.

BUT, i suspect that a single box will not keep the noise down low enough.

can't you have the normal single box for when you use it on the road, and a take off with a closing flap near the back so that for track days you can bolt on a second silencer? it doesn't matter what it looks like on the track, but on the road you want it more standard looking.

some kind of system like the aston vanquish has. when you're pootling around at low load it is very quiet, but when you start ripping it up a flap opens in the exhaust and bypasses some silencing to mae it louder and more tasty.
