KTEC's KTR Manifold Pre Cat Delete Pipe

no not at all restrictive, it just changes the engines requirments for fuel and spark. Quite normal issues. Any decent modifications need mapping to release their potential

Yeah I understand that, I mean the standard ecu will only adjust it parameters within its range hence why the management light issues. So would you say it was a worthwhile modification danny?
 
I was considering this but seems a quite a bit of work and quite expensive for not alot of gains and would be a pain come mot time!
 
All I'm interested in is what sort of gains I'll get with it mapped, I mean I don't expect a lot seeing as its only a pre cat but it just seems like a bit of hassle at the minute
 
Hi!

I have Clio R27 with Akrapovic Evolution exhaust system, so there is no second cat, and today
a saw the check engine on my dashboard....
there is problem with first cat it's full, so what should I do?

I'm thinking about buy used manifold with cat or replace old cat by Y-pipe
KTR or Supersprint
I read a lot of forums, and there is no only one answer, that the remap is necessary

thanks for Your help and sorry for my English :wink:
