Max9650 Posted September 27, 2011 Share Posted September 27, 2011 Hey i have a HKS Silent Hi-Power Zaust and ive got a decat etc, and its not very loud the only thing i can thing of is that it has a exhaust bung inside to restrict the noise? ive had a look down there and it doesnt look like it does, although i think its a like a 3 inch exit yet half way down the backbox it goes quite small down to maybe 2inches? is this normal? sorry i dont have any pictures any help much appreciated Quote Link to post Share on other sites
string Posted September 27, 2011 Share Posted September 27, 2011 i have the hi power which is the one before the silent. Mines quiet on tickover, motorway etc but on boost it has a nice sound. Pipeworks 2.25 i think. If it had a bung you'd easily See it. Mines 4 inch exit? 3's quite small. How loud do u want it? Quote Link to post Share on other sites

federalman Posted October 24, 2011 Share Posted October 24, 2011 Mines getting louder it was pretty silent on motorway until you hit boost and it roars. Think all the centre and back box is finally destroying the packing Quote Link to post Share on other sites
