  1. Hi the WP catback looks identical to a difillipo catback except walkinshaw is stepped from 3″ to 2.5 . Are the walkinshaw mufflers internally different to DPE ones? Cheers

    HI Carl / Mario

    Im looking for a full exhaust system or even the W375 Pack for my VFII SSV Redline.

    On the last WP exhaust I had on my VE only one exhaust outlet tip was full flow whilst the other has a small (20mm) branch pipe feeding it from the muffler. This caused one tip to blacken and one to stay clean. At the time WP told me they were looking into a new system were both outlets would be full flow but it was not there yet.

    Do the current WP muffler outlets both provide full flow or are they still restricted on one outlet.

    Have you got an exhaust compatable with the new HSV Gen F GTS?

      Hi Matthew, at this stage there isn’t one available but we understand that development is underway. More news will be available as it comes to hand.

        I notice on your W507 pack you have fitted a 2.5″ DPE exhaust, previously I have tried the DPE 3″ on my Gen F GTS but had terrible drone, so bad I went back to stock. How is your new 2.5″ system and does it drone at all ?

          Hi Steve, thanks for your question. The system we have on the W507 is a stepped system which goes from 3″ into 2.5″ after the center resonators. Walkinshaw has developed this system to have the least amount of drone possible but with any aftermarket exhaust you should expect some amount of drone in certain situations.

  10. Hey guys,
    Picking up a 2011 black edition Maloo R8 on the weekend. This kit says its for Sedans. Do you provide a similar kit for the Maloo? Cheers.
