just had this wacky idea

[surfenstein]

on the other hand caterham have side exit exhaust dont they??? with heat shields.

[dieselboy]

of course it will be legal. why wont it?
ive made side exit exhausts for loads of cars. i even did a front exit/side exhaust once. it came out the front bumper! but dont ask....

i like the idea of them being in the steps, bit unsure about the 180degree bends though but as long as the ID of the pipe at that point is large enough it should be ok. the sound will be nice and resonant if you have those side steps hollow. you can fit perforated tube inside them for a popping sound

[dieselboy]

get some 180 degree mandrel bends and cut and weld. you will be fine.

already got the bends 2.5" s/s as will the whole system be.

Yep, caterham's do come with a side exhaust. I think you'll find the rules say that you must not have anything protruding from your car that could be considered an increased danger to passer-bys (ie it's all about good judgement). Thus a side exhaust with heat shield should be fine, especially if it doesn't protrude out the side more that your side steps do already.

Surely there'd be way too much restriction in that design?

Far as I know with exhausts, there is no MOT requirement other than them being complete, i.e: no holes, and the sound level being within acceptable limits. Do believe one of the other regs say that exposed hot parts have to be shielded, though, to prevent accidental contact.

ok guy just had an idea and thought i might run it past those that know.i will be fabricating new sliders for stein.and i though i would incorporate the exhaust into them,so the idea is to make the sliders out of 50x50x4mm box section.and use the outer slider as the exhaust outlets.heres a quick sketch to show what i mean.the question is will it be legal.any thoughts.

Feckin 'ell! You're as mad as a box of frogs!

How about something in stainless steel?

[magnum force]

didnt they used to have exhausts running along the sides of custom cars

Funny enough they were called Thrush side pipes, and ya can still get them.
I used to have them on a Mk1 Anglia with a v8 lump and Jag back axial. That was frightening. 1976 i think it was.

do you think i care about restriction??? the system equates to a twin 2" system with nice flowing bends.

theses thing have got to be done,after the bashplate that is.

I know this will go down like a lead brick, but that is still a bad design/philosophy. That design is just begging for problems to arise.

hehe yea i know.what i might do instead of fitting the exhaust to the front of the outer pipe is just fit it straight to the rear of the outer slider and partition it off.as in the dotted line.

If you're gonna be doing 'em, couldn'y you shorten the muffler box if it protrudes that far back towards the rear of the vehicle, to make it so that you could V it from the muffler to the rails?
