sports cat



  clio 172 cup
i have the k tec stealth and sports cat and its starting to piss me off with its boomyness. if i took the cat off and put the standard one back one would it be better or is it the back section that is boomy???

never had a problem with my k-tec cat. Exhaust sounds fine. Is your k-tec system fitted with a round or oval shaped centre silencer?

It is boomy at certain rpm

Is it new as I found the longer it's been in the car the less boomy it has become.

Just had the new ktec stealth system and a Yozza decat fitted and its pretty damn loud. The middle and back box dont seem to have much packing in when you tap them they sound hollow ! So as soon as i floor it, it sounds like devils rally car. I personally like it but the missus hates it !
Was thinking of putting the original cat back on which should cut out the loud raspiness hopefully or will it any other help would be appreciated.
sorry for hijacking your thread rob172cup - at least its relevant :)
 
Rob - I had the same problem. I think swapping for a normal cat would reduce resonance (Charlie at Pro-speed seemed to suggest that when I spoke with him)

My solution was to get rid of the K-tec stealth cat back instead. Replaced it with a Pro-speed stealth - much less boomy now :cool:

Just had my standard cat put back on and it sounds normal again much improved for daily driving ! Not that boomy at all
