Now you can have over-the-top power and torque of open headers
and still meet all of your sound requirements. This 18 gauge steel
Car Chemistry insert fits directly into your header collector and
reduces sound output without restricting power like a traditional
muffler. This three-disc insert is for use on street/strip
Includes 1 plug and 1 restrictor.
For pollution controlled vehicles operated on the street the insert
must be installed after the catalytic converter.
Due to the differences in manufacturing from company to company the
insert may have a loose snug or very tight fit that could require
grinding a very small amount of material off the circumference of
the discs. To hold the insert in place either weld them in or use
stainless steel pop rivets.
Great quality and and I received very quickly.

You can tell customer service is important to this company. Not only were the prices lower than other places but they communicate the status of the order and shipping very well. They obviously care what people think. I was suspicious of all the positive comments but decide to try them anyways. Very happy I did and definitely plan on buying from them again.

This company offers profesional service at a very competitive price. The header collectors i ordered were not available at the big speed outlets. The fast shipping was also a plus. I would recomend Autoplicity to anyone who needs parts in a hurry !
