Speed Secret # 4

[Kevin Price]

A couple of months ago I purchased Moroso's 'Spiral Flow" mufflers. Without seeing the spin techs I wonder if it may not be the same concept. Could you send me in the right direction for getting a bit more info on these?

Back to the Moroso's, I installed them approx 6 inches from the rear of the collector. I simply don't have much room under there. I didn't try them at the track as I could see some additional tuning would be required and the race was the next day.

Car ran fat and just would not idle. Seemed way too restricted at higher rpms. Don't know, I may put them back on this week and o a little playing to see what I might come up with.

As far as a spiraling modification in the collector. I'm interested to hear a bit more. I'm assuming somewhat of an angled fin? What angle and how high? How many?

Hey, I'm always willing to try new things here.
