Adriank Posted November 27, 2008 Share Posted November 27, 2008 I am getting tempted by these at the same time as fitting my 5Zigen exhaust, but i have 3 main questions :- 1. Will it make much difference to the Noise, Response or anything else noticable? 2. Any Downsides to fitting these? 3. What ones have you guys used and would reccomend, and can be got in the UK? I have read threads about them cracking exhausts, is that just some models or all? Many thanks Adrian Quote Link to comment Share on other sites More sharing options...
Ian Posted November 27, 2008 Share Posted November 27, 2008 1. More noise 2. no 3. Mine are custom made but most seem to go for the Kinetix cats Quote Link to comment Share on other sites More sharing options...
P15UL T Posted November 27, 2008 Share Posted November 27, 2008 i had kinetix on mine and they sounded awesome and didnt effect the sensors, i think kevin @ envy do them and i presume big phil @ ESR will do something simalir Quote Link to comment Share on other sites More sharing options...
3FIDDYZ Posted November 28, 2008 Share Posted November 28, 2008 Kenitx and 5zigen Pro Racer on mine. Had no issues thus far. Noise is amazing If you havnt got the plenum spacer get that done at the same time! Oh and you are getting the y-pipe too arnt you? Envy do stock these parts and I belive they may have some ready to fit Quote Link to comment Share on other sites More sharing options...
Pingu2 Posted November 28, 2008 Share Posted November 28, 2008 also have the kinetix (paired with nismo exhaust) - they add quite a bit to the sound of the nismo, as people behind me in the tunnels on the way to brighton a few weeks back will attest.. they should allow for greater airflow through the exhaust system of course, and I have had no trouble with sensors with mine (which were installed by the local muppet) which I have had on for over a year now..

IanS Posted November 28, 2008 Share Posted November 28, 2008 Heard Hi-Flow Cats reduce torque, any truth in that? Quote Link to comment Share on other sites More sharing options...
3FIDDYZ Posted November 28, 2008 Share Posted November 28, 2008 Not hiflows as they still give back pressure... It may have happened to some but this can be caused by an illfitting joint and air leaking. It can happen if you go straight through with test pipes!

Darren-B Posted November 28, 2008 Share Posted November 28, 2008 ive the got the kintex cats on mine, found that when the zorst is not hot there a little raspy, makes the car sound a little like an E46 M3, but keep them warm and they sound lovelly Quote Link to comment Share on other sites More sharing options...
cgomez1978 Posted November 28, 2008 Share Posted November 28, 2008 do they give you any more power or do they just give you a better sound Quote Link to comment Share on other sites More sharing options...
3FIDDYZ Posted November 28, 2008 Share Posted November 28, 2008 Sound first, but depending on what other help you have like a piggyback, they can help a little as they are more free-flowing than stock Quote Link to comment Share on other sites More sharing options...
cgomez1978 Posted November 28, 2008 Share Posted November 28, 2008 cheers mate ill just buy the plenum spacer for now then as i think this is the best way to get some extra power and a lot cheaper than a ECU Quote Link to comment Share on other sites More sharing options...
3FIDDYZ Posted November 28, 2008 Share Posted November 28, 2008 It all helps a little bit when put together... ANd then when its done piggyback it to make up the updates work! Quote Link to comment Share on other sites More sharing options...

Ian Posted November 28, 2008 Share Posted November 28, 2008 Heard Hi-Flow Cats reduce torque, any truth in that? Decats will. I lost 40 ft/lb with decats in, Sounded amazing though Quote Link to comment Share on other sites More sharing options...
