  1. #1
    Ok... i just wanted to ask if i change my Supersprint decat centre pipe, to one with a cat will it make much difference?

    And is the a Back Box that will make Quiter as i wanna keep my mani

    EDIT: just found out it drops it by 14dbs

    one with a mid silencer will drop by 12-14db. You could fit your cat and run a cat back supersprint which will be quieter than a straight through but sap power.

    I have a raceland 4-1 mani on the car. But I wanna keep it on. Ain't really fussed about power! As I don't race nobody!

    Just wanna know if I add the under car cat. Will it make a difference.

    I know u just answered that question but will the 2" supersprint change it?

    from experienc, adding a cat will certainly make the car quieter mate.

    Same here, 4-2-1 mani, decat, silenced centre section and stainless back box was loud and raspy cause of the decat, put cat bak on and doesnt seem quite so lively now but less noisy and a deeper noise!!

    the decat gives it a different tone. makes it a bit louder but makes it more raspier if anything.
