My 90 C4 came with a sport muffler, cone filter and a Weltmeister chip installed five years ago. I have since reverted to stock and have had these parts hanging around since then. I have also tried Wevo mounts (black pads), thought they were too noisy and removed them. I installed a 911Chip trying to tame idle bounce. Made no noticeable difference in idle bounce, or performance for that matter. The Weltmeister felt very much like the 911Chip.

1. Mille Miglia sport muffler, made in Australia
2. Eastwood Cone Filter.
3. Weltmeister chip
4. Wevo mounts, black pads.

The car was sold new in Hawaii, so I guess parts 1-3 were sourced in Australia.

Please PM me if you're interested. I'd prefer to sell the pieces together. Asking $500 for the lot. The muffler is large and heavy so shipping will be expensive. I am in SE Virginia, US..

Here's some pictures.

I think I see the vacuum cannister that operates the resonance flap in the pic so I hope your engine currently has one.

Hope you solved the idle bounce. I also bought the 911chips chip to help sort out the bounce. In the end, the solution was the cheapest & easiest .... a system adaptation! Instant fix.

I will take the Wevos.

Make sure your clamps on the ISV valve are nice and tight, preferably with screw-type clamps and not the stock crimp clamps. Any air leaks pass the clamps will make the idle hunt a bit. I replaced my stockers with the screw-type clamps and my idle problems went away (idle adaptation important as well...especially if you've ever disconnected the battery).

PM sent, I'll take the intake setup if you decide to break up the lot.

how much are you asking for the muffler if you decide to part out?

Sorry I'm late getting back. Here's some answers.

Steve: I put a stock air intake on, but can't recall if it had a canister attached (it was several years ago). I'll check it out thanks.

Simon: The stock chip reduced the bounce so much I haven't bothered to do the adaptation. Now that its gotten colder, its a bit worse on start up. Hope all is well.

Greg: Looks like I will part it out, considering the offers.

August: During the 'hunt' for a solution I even tried changing the adjustment on the ISV. No effect at all. As Simon points out (I wanted to say Simon says..) the adaptation works.

jpar: I'll get back to you.

911Wings: I'll send a PM on the muffler.

Thanks all for the responses.

Seems the only part that doesn't have a taker is the chip.

Hello, I would be interested in the chip, what differences did you find? price?
