I looking to replace the conical gasket that joins the down pep to the system on a classic. The price is much higher for a turbo one compared to others. £4 odd for a sport and £20 for a turbo. Is there anything special about them?

 

They are bigger and the market is larger.

 

Measure it to get it cheaper rather than going off make and model. If it's standard it will be 2.5 inch. If it's after market it could be 2.5 or 3 inch.

Both are here at a good price.

Still plenty left and well under £20!
