I need some help identifying my exhaust or finding a suitable replacement. at some point its been opened up and welded back but theres a terrible baffle/rattling noise at low rpm that ive isolated to the back box.
Car is the 2007 S2 Exile Cup 255.
When looking at replacements, most seem to be a single tail pipe however mine has two. the diffuser is also specifically shaped for the two pipes.
FWIW, I think you probably have a Lotus Stage 1 exhaust on that It was different from the ‘standard’ exhaust (which sounded like a sewing machine) and gave a nice noise. The Stage 2 was the single, oval exhaust that required the diffuser to be cut a little to accept it.
I think this is what confused me, when I tried to find the same one, it only appeared on the NA cars, despite the picture from the brochure showing what you have posted.
That looks different. in That the ends of the pipe are rolled. mine are straight cut. not sure if that makes much of a difference. I’ll have to pop the diffuser off for some better pics tonight.
Is the seller on this forum or do I need to sign up to midland to message.
Back in 2004 I bought a new 111R. It had the ‘sewing machine’ standard exhaust (narrow, twin pipes, straight cut). I got a stage 1fitted. It was still 2 pipes, wider bore, slash-cut. Then I got a stage 2, and that (at the time) was a single oval, MUCH louder. I didn’t know there was a twin-pipe stage 2 - very interesting!
All the Lotus ones have a part number on them - LOTAC-something-or-other
FWIW, I had a quick look on SJSportsCars site - and…
LOTAC05334 is Stage 1,
LOTAC05391 is Stage 2 with dual tips,
LOTAC05450 is Stage 3 with oval tip (that looks very much like the ‘stage 2’ I had on my NA)
After sourcing a replacement from @sjw (thanks Steve) I cut open the old back box to see what rattle was. A baffle at one side had come off. And what remains of my cat is also in there.
