Anyway, at the San Francisco region's Spec Miata Festival at Laguna a couple of weeks ago I won an ART tuned Air Flow Meter during the raffle. The car pulled a lot harder up top. It felt very good.
In my last race report, I told you that a friend of mine drove my car in ITE at Laguna. I watched from the grandstands and heard just how quiet the car was with the stock exhaust.
I definitely needed to fix that issue too...
After checking out fellow SM racer, Juan Pineda's cool custom exhaust (by Evil Genius Racing) and feeling what the ART tuned Air Flow meter did, I decided I should get an exhaust. I thought about the Springfield Dyno exhaust that many people run. However, the fitment issues some people experienced scared me off. Plus I'd have to take it somewhere to get the rear part welded on anyway.
Another complication with exhaust here in the San Francisco region is Laguna Seca. We have to meet stringent sound levels when we race at that track - approximately 90db. The Springfield Dyno exhaust is much louder than that. Many people have the local race fab shops add a second muffler to the rear of the Springfield Dyno exhaust to make sound.
So I decided to go to TC Design since Tony built my cage, he is nearby and he does awesome, timely work. TC Design builds his exhausts so that you have 2 rear sections:
- A straight pipe that exits straight out the driver rear.
- Piping and a performance muffler that exits at the stock location on the Miata.
So I scheduled an appointment. Dropped the car off this morning. Picked it up this afternoon.
My car finally sounds like a race car. Fixed that "problem". Should have more power also.
I'd take a pic but its not easy to do in the garage. The next race video should sound racier!
