I just had my 93 cup car replica out on the track for the first time this weekend. It ran amazingly well and with the cup exhaust it sounded phenominal...and the flash of flame on downshift looked cool to specators but, the open exhaust toasted the bumper pretty good around the outlet...so it begs the question, what are you cup car guys doing to minimize the damage?

GT3 Cups come with a muffler and integral catayltic converter which rests perpendicular to the rear bumper, just inside of it. They're wrapped with a fire proof insulation blanket which effectively protects the rear bumper.

We run stock chips and stock heat exchangers and they don't flame as a general rule. It sounds like you need a slightly longer exhaust tip.

I have no such known issue. As Geoffrey noted, we* run the stock 964 Cup chip, perhaps you're running something else?

*we = the group of 964 Cup guys from the east that regularly race their cars in PCA that I'm familiar with

Charlie, Geoffry,

I think I might be running too rich on overrun, and I'm getting flash on downshifts, I had a Dansk tailpipe on the carrera cup exhaust and factory headders (no cat or sport premuffler), I think I'll just put the factory tip back on, and check the FI... I had seen where someone had fab'd a nice aluminum surround to deal with the hot exhaust but I guess its not a common problem, I still have some shakedown to do...)

(charlie, cars still in white, getting ready to go with the cup graphics, I'll follow up on the rest soon...)

thanks

Hey there,

I had an Al piece fabricated on my ex-Cup and will be doing the same for my new RSA. Unfortunately, I do not have any pix, but can put you in touch with the guy who made it. FWIW, the piece looked great---looks like a factory piece.

Hey, good to know! I liked the French Carrera Cup theme, if you want to go with that instead of what we sent you...

Mike, I was over at Dan's the other day and was studying that tail piece. It is very nice.

K964

Hey Charlie,

Hope all is well. The piece is nice---I will have another one made up for me soon. Let me know if you want one as well.
Mike

ps I still miss the old girl. Even with a pretty good selection of P-cars, my garage will never look the same......

Cayenne Turbo, nice! Is that a new acquisition?

K964

Yeah, I took some of the Cup $$$ proceeds and bought a CPO Cayenne Turbo with 15k miles---I got a smoking deal from my good friend at Hennessy. Then I just bought a '93 LSD-only fully track prepped RSA (30k miles) with the rest of the $$$.

The CT is simply amazing and does everything I need it to---almost makes the Turbo 3.6 expendable. Nah, not really. I'm just going to put a lift in the garage to accomodate my 4 cars.

Nice! I'd like to have a Cayenne some day...
