will decat dwn pipe make more noise!
 

alright everyone! just wondering if i fitted a decat dwn pipe or a sports cat to my afterburner exhaust would it make it louder... cheers!

if you havent done so already replace the centre pipe. MOT will still be a pass as long as you have the cat on the turbo. Alternatively strip all the cats - hope you dont get pulled and mess around changing them when MOT comes.

yes it will !!!!!!!!!!!! better burble !

Iv got a vortex afterburner back box and when i fitted my de cats it made quiet a bit of difference. better performance, much louder. But a nice loud, and can hear the turbo spooling up.
Soooooo much better ;)
