There is absolutely a cheaper alternative to PMNA on these types of things. It's ludicrous how much some of these specific parts cost.... I don't know who makes it but I guarantee someone can do it for less than $5,500 (and I remember when PMNA was selling them for $8k...). That said, the thread is deviating a bit from your proposed rule change ("any Porsche supplied..."). I have zero problem with GMG or someone else coming up with an alternative. However, in "stock spec" classes like GTC, I think the less deviation the better. Offer two alternatives or something like that but when you start messing with exhaust AND headers there will be people that are doing it for performance gains and the cars will start to be different. In spec classes, different isn't good.

By the way, rule changes like this, where the GTC3 cars are now primarily run in Club racing, will get PMNA's attention.

The proposed rule change is one I instigated, but not one I got to write. My personal view is the same as yours and as been discussed in this thread: functionally equivalent, no performance changing non-Porsche mufflers should be allowed that exhaust in the factory location, but no change to the headers or other exhaust elements should be allowed.

The PCA staff came up with the idea of using some other Porsche supplied item which, as far as I know, does not exist.

"The 996 Cup is going on 13 years old now. Finding parts like mufflers that are often destroyed in minor incidents is getting tough, and expensive. Think about it, $5,500 is 9% of the value of an older cup. To pay that for a muffler is silly. The rule should change to anything that connects to the stock, un-modified headers and exits in the factory location should be acceptable."

+1 comment sent to rules committee, thank you for bringing this up. It is only a matter of time before we have to replace it..............

I agree with this clarification. Parity is important in a spec class. Look at spec boxster; I have a friend with $50k in his.

Thanks, Dan. Must be the new computer system Michelin/Jackson money bought. :-)

The 964 Cups racers were allowed to replace the super rare, and fragile Speedline wheels for aftermarket wheels to save money. 944Turbo racers for safety could install billet aluminum fron A arms for cost savings.

993 Cup cars that race and therefore run stock OEM catalytic converters will burn these out and cores will fail will require replacement with used street 993 cats.

As any and all of these CUP cars get older and used up..........exhaust should be free in some respect as heat cycles and off track excursions will require replacements. Porsche AG eventually will not want to support earley watercooled race cars just like they abandoned aircooled 964/993 race cars.

If anyone in the tri-state area wants me to design a 996 GT3 race muffler or 997 GT3 rear race muffler I am more than equiped to do it. Fabspeed Motorsport USA finally completed the move into a new facility and we now have 38,000 sqft devoted to design, engineering, fabrication, and manufacturing.

We have the worlds most advance defense contractor quality all electric CNC mandrel bender and we are the only company in North America that can bend 1D on stainless steel tubing.

Cruise by and see the facility you are all invited. 1/2 mile from the Fort Washington exit of the Pennsylvannia turnpike. Details of Fabspeed capabilities on my website.
