Installing a late model manual transmission, specifically the TREMEC T56 six-speed, is one of the most popular upgrades for a classic car these days. Especially when something is being rebuilt in a pro touring style. Besides offering more strength and gear selections over the old-style four- and three-speeds the old cars have, these transmissions use a hydraulic clutch actuation that’s way easier on the driver.
With the T56, the hydraulic slave cylinder that activates the clutch is mounted on the bellhousing. This places the slave unit in very close proximity to the exhaust, especially when long tube exhaust headers and true dual exhaust are installed, which is the case with most vehicles the T56 is being retrofitted into. The body of the slave cylinder i
There are a lot of myths, malarkey and horse manure out there when it comes to exhaust wrap. The biggest pile is that exhaust wrap destroys your headers. This is a misconception that scares people away from using exhaust wrap to increase performance. When you wrap exhaust headers, more heat stays in the header pipes—which is what you want.
Where the misconception comes into play is with what happens after the wrap is on. There are a multitude of headers out there and therefore a variety of alloys for tube material. Metal alloys have a minimum and maximum temperature rating for what they can withstand. Extreme cold has major effects on metal just like extreme heat does. That’s why aircraft aluminum is designed to withstand extreme cold way more than extreme hea
