Hi Terry,

 

No high flow cats for forced induction, they all get burnt out, you will need to run test pipes/decats. 

 

We have the TORQEN Helmz or just the standard ones in stock, links below.

Standard decats: https://www.torqen.uk/nissan/350z/exhausts/test-pipes/18247-350z-de-z33-torqen-decats-test-pipes-trq-vqde-tp.html

Thanks for the input once fitted will I have to put standard cats for mot?

[Coz@TORQEN]

Yeah, unfortunately so, unless you have a “friendly” MOT tester.

Do the Helmz pipes lower the db at all Coz, or are they more about altering the tone of the exhaust note?

They’re designed just to reduce any raspiness and drone, make it sound a bit more V8-like. Can’t comment on the actual DB readings between both as we haven’t tested that extensively.

Haha I think there aren't 'friendly' MOT testers left these days with all the requirements of running an MOT test nowdays
