Indeed, but wouldn't the light come back on at a later stage?Oldskoolbaby":2oiqzbkd said:
If so, then that means one would need to be aware of the following:
a) the need to keep switching the light off
b) one would never know if there is a real issue (may cause issues if one keeps driving with the light on assuming that it came on due to the sports cats)
c) one would need a friendly MOT chap to get it through.
The above are the reasons why I haven't taken the plunge with the Janspeed full system with sports cats. I have been told that it may be possible to eliminate the light with a remap and repositioning of the sensor, but I don't know of anybody who has had theirs done successfully.

Well done! hit the nail on the head.
the whole idea of a sports cat is a compromise, if you need the guarantee of 100% not activating the light you must stick with standard cats and their strangling performance, as soon as you go to a sport cat you open up the possibilities of occasionally putting the light ON.
Not that I want to put anyone off the idea but the last thing I want is to get these made and then get swamped with a load of angry club members wanting their cash back, which incidentally would be an impossibility as the cats will be welded into your own pipes.
There is no more risk than using the janspeed cat header as I will probably be using the same cat.
Remember , performance is a compromise when asked for with reliability. you have to accept some issues when fitting race parts, and this is what these will be. there are NO warranties when you go racing! Please bear this in mind.

I was looking for something similar from Jetex but found this. There are ways of permanently removing the fault code issue. I'm sure jetex or another company produce small, sensor sized cats to fool the ecu everything is ok. At the end of the day, unless you map the car differently, it will always be a case of fooling the standard ecu. That's just engine tuning for you. With sport cats, you won't have problems with the MOT man as the ppm count should still be lower than what VOSA require for a road legal car of the V6's age.

Iain, did you see all the new crap I bought ?

Might just stick it in somewhere and get them to deal with it

Hmm good question, IMO these are a good setup if you have a phase 1, my way of thinking with the ph2 is that with the extra power the pipes are a little small. reasons for this is to get the bends in with the cat and of course the car was a lesser powered vehicle. there are some that have fitted these to ph2 models and gained much dissapointment from them and little else.
So again,MO why bother going to that sort of expense plus however much to fit the same , and loose all the std heatshields is a mystery to me, and yes you can coat the pipes and wrap em but it all adds to the cost to obtain very little at all, a bit like sex!
So if we could find a way to change just the cat, and combine that with a large bore free flowing silencer (who does one of those?) i think we would be 80% there with a lot of change from about £2.5k (£1699+ the extra bits). of course, you will not fit these manifolds without the silencer will you? and how much are they charging for that!
Add this to the fact that most of these cars are now 10 years old, so where you going to buy cats from RENO! dont make me laugh, do you think that renault hold 250 sets of spare cats for these, i think not. i think it a "when its gone its gone deal" and we ought to sort this now whilst its on our minds.
Presonally i have got spare cats with low miles so i can take it or leave it , but as i said with enough takers i will get them made.
I wouldn't think of spending a penny on sport cats unless the shitty cast manifolds are ditched altogether. My mate had a look at mine when the L7X was fitted and reckons the most effective way of doing it on a small n/a transverse V6 engine would be merging both banks into one (like the Trophy cars do), filtering the gasses through a single high flow cat, then splitting back into 2.
Failing that, turn the engine 90 degrees and have a perfect equal length system. I took his advise and did the later! Lmao

It's no secret here that I have the full Janspeed system with sports cats fitted to mine 3 years ago.
"Do I regret it?" - Not one bit.
"Did I fit it for power gains?" - Nope, only for a better sound (IMO) without the drone of the QS system I had on the previous v6.
"Is that the only reason?" - Hell no, the oem system weighs almost as much as the car does again, so I wanted to ditch some of the rear heavy weight and still enjoy the odd steak or 2
I even considered adding some of the weight saved to the front of the car with some corner weights.
"Does the dash light come on?" - Yes, eventually. I just reset it again.
"Have you had it live mapped" - No I haven't. Though I'm led to believe this would solve the light issue. I just cringe at the thought of someone reving the nuts off my car while its tied down, and all the risks that go with that scenario, all to fix something that isn't really broken. I'm not interested in a tenth of a second off a 0-60 time, or if I can squeeze another 1mpg out of it.
"Overall are you happy with what you have?" - Personally, yes.
"Would you not buy one of Spikes systems should they go into production?" - Yeah, I probably would... because its designed for the phase 2, not a phase 1. That, and I wouldn't have to worry about resetting the dash light! Lol
Look forward to seeing the complete 'Spike' system sometime soon
:approve:

WELL SAID.
I left the whole quote in as it sums up quite nicely, do it cos you want to, because you enjoy it, not because some arse has a bigger one or a louder or faster one, just enjoy.
some on here just get a little carried away ( and if the cap fits Brett) , yes we know the routes to make power, but if that is what its all about why did we all buy this small piece of french junk?
Just let me make things clear, i am not in a power competition with anyone here i am just trying to offer an alternative to a full decat system that will keep us within the law and is reasonable to buy and use, cheapish with reasonable manners.
The most sensible option to me is re engineer the original pipe with a decent sports cat that can be fitted and does not look out of place for a reasonable sum of cash, that way when the cats do start to fail (and they will as they do not last forever) there is an option instead of being held to ransom by reno. of course once the jig is made you could just replace the cat with a standard one if you wish, of course cost would be different but thats all ( and dont make the mistake of thinking that would be cheaper as you would be shocked at the price of cats). this whole idea came about by someone having a cat failure and the sport cat idea is just an extension of that. the idea of using the original pipework eliminates fitting issues and also gets round the recent change in the law that says any cat destined for a car from 2003 must be tested and type approved or it will not pass an MOT. The days of the freindly tester are coming to an end, also the recent speights of roadside testing do nothing to put you at ease.
Janspeed do make a quality product and the manifolds are no exeption, also they seem expensive but trust me for what they are they are cheap, and as shaun said the weight saving is enormous. And pass an MOT. however not all of us have that sort of money to spend on headers and of course there is the cost of fitting, a simple cat change would be easier, read cheaper in hours and particularly if the cats were done on an exchange basis. as i have already mentioned i do have a spare set (two actually) so this could be just a days job if it took off, one off , one on etc.
i am sure there will be many comments to this, just dont have a load of beer before you reply, think of what i have said and think of this as an option .
