Marving cat eliminator

[Duke Konan]

I'm thinking about getting one of these for my S2R 800 https://www.fastweb.co.uk/spaceshack/cart/index.php?main_page=product_info&products_id=4

I can't justify spending on a full exhaust system at the moment but I've heard that removing the cat improves the exhaust note considerably and it certainly cleans up the look!

Has anyone used these before? What's the general verdict?

[Scott1]

I got one of these last year, well worth it, ditch the bagpipe and it sounds much fruitierand looks much better, I'm sure you won't regret it.

I'm in the same boat and would love some tail end pipes...maybe next year.

Good luck.

[Duke Konan]

Scott - good stuff! Did you have to have the bike remapped or anything of the sort or could you simply swap the pipes?

[J.P]

re-mapping would be the best bet if you're going ahead with the de-cat pipe.
It's worth the money simply to improve the bike's running.
The exhaust note will become deeper and throatier without going to the effort of new slip ons

Any opinions on this? Their both pretty similar in terms of price but the Quat-d description says it accepts the standard lambda sensor whereas the Marving doesn't say anything about the sensor.

[J.P]

If the bike has the lambda sensor, mine did, then up to you what the final cost will be.
If you exclude the sensor, you can't get the bike tuned properly until you change to a performance ECU, very expensive.
If you leave the sensor in, then that elliminates that problem, and cost.
Quat-d seems the cheaper option, though I went the whole hog and changed the ECU and had the bike dyno'd. You can't leave the sensor out without the new ECU, it muck's up the low revs and caused lots & lots of problems.

[Scott1]

Ah, mines an 05 model with no sensor, I didn't have any re-mapping, keep meaning to get round to it but it runs fine in the year I've had it done. Performance wise, I couldn't find any difference when riding out with other S2R's.

[Duke Konan]

I think I will probably go with the Quat-D mid pipe for now and look at upgrading to aftermarket cans down the road!

hi do you know if it would be the same for a s4r 2005??
again prob need to wait for end cans . any advice would be nice
