Hi after your thoughts on downpipes,either looking at a T75 from power engineering or the TSL "Group A" Spec Performance Downpipe would like to use one of these companys so I can get a Tek 2 ECU Upgrade done at the same time. I have the mid section cat out at the moment,but was thinking of putting it back on for MOT time. 1. which down pipe
2. which company does the best map of the ECU?
3. Will car pass emissions with either of thoes d/pipes and ecu and the mid section cat in?

Thanks for your thoughts and comments

any one?

 

With regard to questions 1 and 2, you will be hard pushed to find people with experience of both pipes, and you'll be even harder pushed to find someone who's had a remap done at both places, and is thus qualified to comment on their relative merits! About the best you can do is search on here. I'm sure both companies do a very good job.

With regard to question 3, it should be possible to get your car through an emissions test with the centre cat fitted, provided it is in good nick and warmed up.
