Tophat Defender LT1 (budget serie)
We already produced the headers for all Tophat’s LS3 equipped Defenders, but they switched from LS3 to LT1/4 engines, so a new header design had to be made. In this case we got different demands then usual and true equal length was not priority number one. But it still had to make a decent amount of power and torque. The exhaust also had to fit each model, including the Range Rover model. Not the most easy job as Defender was never build to house such a big engine. It took some iterations but at the end it became a very (cost) effective header. We produce them now in small series for up to 600HP.
