I had a 99 miata that was built much the same way.

The reason i even bring this topic up is because of what Van told me. He mentioned that the stock midpipe is extremely restrictive after the resonator and a lot of power maybe lurking in that kink.

Anyhow, long story short, i plan on doing what i did with my miata and having a custom mid pipe built which will include a hi flow cat and resonator so it stays completely legal. Im sure that with a nice muffler this set up alone can yield an honest 5 horses to the wheels. Thankfully, I also have access to a dyno so everything will be documented and printed. The nice thing about this is that it will be a complete bolt on affair so if you have a stock rear set up or another aftermarket set up, you will def notice the improvement.

Would anyone else be interested in something like this? Im sure if we can get enough heads into this, the cost will not be much. So who is with me?????
