Rear Exit Exhaust
Discussion
A friend has told me about a rear exit exhaust system for Caterhams.
I am not keen on the common side exit exhaust system and was wondering whether the rear exit exhaust system exits out of the side panel or whether it runs underneath the car and does not exit out of the side panel.
If anyone has any photographs that would be great.
Cheers

Allen, you don't mean that the whole system run under the car do you? It's just the transfer pipe between the silencers.
Here are pics of the CSR 175 EU4 setup
No matter which way you cut it, you've pretty much got to have the exhaust emerging from the engine bay to one side or other, then the cat, then a silencer system. The rear exit is largely just to provide a second step of silencing. In the end someone's got to burn their legs. In a Levante, everyone does!

Canam's reference is to the Xflow cars with a rear exit exhaust. The exhaust still exited through the side skin and had a side mounted silencer (to ensure you burnt your leg!) but rather than have the angled final tail pipe, this was extended as a straight piece to come out from under the rear arch and be bolted to the chassis just in front of the fuel tank.
I do seem to recall seeing some exported sevens though where the exhaust went under the car and not through a side skin and joined with a rear mounted silencer. Maybe somethings for Swiss registered cars?
I reckon rear mounted systems are going to become more common as noise regs become more stringent for track days

Oz Caterhams as supplied there locally for quite a while had rear exit exhausts as did a number of Se7enesque cars. Odd thing is they all seem to fall off to the nearside after their respective style of IVA there. See some old Lotus 7's with rear exhaust, and a couple in the USA.....just a straight pipe running alongside the tranny tunnel to a silencer in the rear...
On my old R500, I had a rear exit zorst. It came out the side, did the 4-1 thing into the can, then ran along and under the wheel arch to the box mounted underneath the back.
Along with an airbox it made the car quiet enough for bedford. It lost 8bhp. On a comparative RR test, with the rear exit was 222, witht the standard side exit it was 229.

made one for my HPC, http://picasaweb.google.com/kevrusselli/RearExhaus... it worked well for noise, tested static at cadwell 89 db, but had clearance issues with the 63mm pipe under the chassis,may re visit this in the future if there is a need. on the good old side exit again now around 95 db at 5000 rpm static at cadwell.
