Firstly id just like to say... WOW...... DKF..... youve made something of rare quality, definatly THE best solution for the z4m in terms of exhaust, youve knocked everything else out the park imo......
ok roffle.... i think for us the Best option would be, s-pipe, race cats, sport rear mufflers... This way we will get a nice sound and maximum flow, we will also keep some much needed back-pressure, being supercharged, we *could gain a good 30 crank Hp here, but will we loose valuable Tq??? i honestly dont know.....
The race cats being 100 cell will be the part that nets us our gain.....
we stand to REALLY gain from this exhaust roffle.... Big time... not to mention drop some weight.......
Will this work with our sensitive tunes???? who knows??
ESS told me they feel the stock Euro system is about as good as it gets for the s54 and they feel bmw made an amazing system...... i do agree they did an awesome job... but their can always be improvements.
