Description
E60/1 M5 + E63/4 M6 High flow primary cat upgrade for stock headers.

Stock primaries, replacment 100-cell grade 1 HJS catalytic convertors fully assembled and welded with flange as a direct bolt on solution to stock downpipes.

As you can see from the picture the CAT's are very large and present an excellent power increase through the rpm range (dyno graphs in pics)

The taper from the collector to CAT and CAT to flange are long and smooth aiding smooth air flow.

This is an ideal fit and forget solution unlike a decat setup and present similar power gains.

HJS manufacture different grades of CAT and these are their premium quality ones.

You will not fail an emissions test which is done by measuring C02 and hydrocarbon levels with a probe in the exhaust tail pipes.

As far as the CEL light goes, we have had no issues at all.


*(There is a core charge of £ 1500.00 which is refundable on return of good un-damaged stock headers)*

Estimated Volumetric Shipping Weight : 15.00 Kg
