I had a long meeting with the guys at Mondello's yesterday.
A variety of approaches were discussed, and I gave them a pretty good budget to do their development experiments with. My instructions were to get the best bang for the buck that they could get, and I didn't limit what they could do with it. Whatever would give the most, is the instruction, as long as it wouldn't put the final price out of range of the buyers.
I also stipulated that I'd like to be able to offer at least 2 "stages" of performance, so that people on a budget with modest performance improvements wouldn't be forced into a high price option.
One of the biggest things to come out of the meeting was that they think they may be able to get enough flow improvement out of the exhaust port without moving it around, or enlarging it beyond what the stock pipe can take. This is still a conjecture, but they stated that they might be able to do that. It that turns out to be the case, it could save considerable money from not having to buy the aftermarket exhaust pipe. I think the telephone pole muffler will still have to go, in any case, though.
I always try to keep the costs down by any means possible, as long as I can deliver what's needed in the overall package.
So, we'll have to wait a while, to give these guys some time to work on the development processes. They have the green light and a budget, and if I have to increase the budget along the way, I will do that if it means getting a better result.
