Just fitted me k-tec twin 3" exhaust yesterday after months of the standard renault rattles, heres what i think of it so far for any1 thinking of purchasing one....
To start of im not overly impressed with the build quality of it, i dont mean to dis k-tec as i know a lot of work must ave gone into it but for £350 squid its not even on par to the magnex quality ive had in the past. Also the baffle in the rear box was making a annoying tingling sound i had to sort out cos it hasnt been welded in that great
Fitting isnt too much of a hardship, the brackets work ok and i got some U-bolts with it too which is handy. Make sure you get a proper gasket from renault tho as the one i ordered ended up being too small
In terms of sound - the new quiet system so it were is in a few words -Still loud! its close to border line of being "too lound" but not quite, it got a real deep burble to it and gets loudest between 3000-4500rpm and then seems to quieten down a bit... neighbours are probably gonna hate it but it sounds good when u give it some, mite be a bit tiresome on steady motorway journys tho
All in all it doesnt rattle - and thats why i bought it! One thing i really have to b**ch about tho is the fact that only the tips of the tail pips are polished, the rest is a brush finish!! I think it makes it look well cheap and im gonna move it further back more this week to hide it as best i can.
