Remap after de-cat

[xoldog400]

Is it necessary to make a remap after putting a de-cat and complete Group N exhaust?

 

[hipwell]

Not entirely but youl see maybe a couple bhp more with a good remap.

 

[Fletcher]

Not necessary, but probably worth doing it TBH.

Just out of interest what grp N system have you got/ are getting?

 

[domjolly]

yes i would say so my car and quite a few others on here got s flat spot on the rev range mine was at about 4k rpm when fitting my decat. I would definatly get a remap im saving at the moment.

i'm getting end of this month a Powersprint Group A exhaust. They are Supersprints sister firm in Germany.

if its anything like a supersprint its raspy as hell when de catted (in a good way though)

 

[xoldog400]

It's the exact system as the supersprint race for 172

Powersprint IS NOT a sister firm. They were our distributor, then they copied our systems and now they sell cheap copies made in China. No TUV approval and I can assure you the quality is not the same.

BOOM!

and thats how it is!

i didnt know that Gardus, cheers for the info

My friend ordered for his escort cosworth couple years ago powersprints complete race system - 1.5 mm thick material, completely no rust, sound excellent!

I'm not sure about what they sold a few years ago, but what they sell now...well you can test them yourself.
Quality issue aside, I find what they did was very untehical, they just based all of their products on our designs. Obviously they can make them cheaper as they don't have any R&D cost, and they don't do TUV testing (as you can see in their website, they talk about european homologation, not germany E1, much more strict on noise levels). The cats are a lot cheaper than the HJS we use.

i don't need a TUV testing...and about the quality i talked with some guys on german and swiss cliosport forums who have them and they are really satisfied.
Two of them use this system on their track clios.
On many german forums you can read ONLY postive expiriences with powersprint (polo cup, scirocco, bwm, wv gti, focus rs) considernig quality and gain.

Still only a copy at the end of the day the original will be better.
