Speed By Design’s new CopyCat Killer Lids originated from our original  Crazy 8 Lids. We have removed the fin and added the option of running a  horn. The new lid is designed to utilize the Hertz ST 35 horn. However,  if you would like to run the ST 25 it will fit as well!
Quality and finish! Just know that we have made lids like these before.  Our tooling and manufacturing process remains the same. The new lids  will fit and function 100% properly and have the same quality and finish  you can always expect from Speed By Design.

The CopyCat Killer Lids with 8 inch Hertz SV 200.1 Speakers and  ST 35 or ST 25  horn… Will be the best sounding lids on the market.
