Red,
Excellent idea and excellent choice using Stainless Specialties.
I have the original prototype set of these ceramic mat pipes built by Lou Berger. Mine are cut and flanged aft of the pipe merge and have 12" long open header collector turn-outs made by Lou for track use.
I dyno'd both configurations for back-to back- comparison on Lizzard Racing's chassis dyno.
The car made 462 WHP on open headers and 457 WHP with these side pipes. Made eight runs up to 7000 RPM for consistent results. A 5 HP loss is amazing. The original mild steel/glass-packed pipes from ERA were 53 HP worse.
I also decibel-tested at 3000 RPM. Open headers and the ceramic mat sidepipes were exactly 103 dB EACH. However the mufflers have a different tone than the raw open headers-but just as loud to the test instrument. I love 'em and it seems you will too.
Stainless Specialties makes complete sidepipe units for ERA's Contemporary's
and several other makes as well as custom work such as you have ordered.
I'm not affiliated with the business in any way other than as a customer, but much like the Weaver's and the Kirkham's for example, Stainless is a quality, family run business and good folks to deal with.
