1 5/8" Big Bore Heater Box Kit, Upright Engines, PAIR (Left and Right) means you no longer have to have to choose between a good flowing exhaust, OR good heat! These are unlike any other big bore heater boxes, with full OE style cast aluminum finnage around the tubes in the heater box shell!

Furthermore, these allow you to do away with those stupid exhaust doughnuts! This kit comes with exhaust flanges to weld to the heater boxes, to match the header you are currently using. This means you have real gaskets instead of that stupid exhaust doughnut that always leaks! Remember that exhaust tubing is measured on the OUTSIDE DIAMETER. These are a lot bigger than stock heater boxes, which are small but also have a REALLY thick pipe, which constricts the ID of the tube.

If you choose the black/raw one, it is HIGHLY SUGGESTED that you remove the paint on the exhaust and paint it with some POR-20 (silver, black, or gray) that won't flake off. Obviously the ceramic and stainless steel versions do not have this issue.

These J-pipes ONLY fit exhausts using a stock heater box location, such as the Vintage Speed exhausts, stock mufflers, Tri-Mil systems, Bugpack Street Headers, etc. These do NOT fit alternate J-pipe locations like A-1 fully merged or sidewinder headers, etc.

We always carry the finest quality muffler available, not the Brazilian and Chinese ones that rust out in under a year's time! These are European, and the actual country of origin can and does change. Sometimes it's German, sometimes it's Danish, or another quality European manufacture.
