Thanks Brad - that was the type of info that I was looking for.brad @ evosport said:Hello,
I am not sure why your call went so sideways. I am sure there must have been some misunderstadning as our salesmen are much better then that. However, everyone has a bad day, so all I can do is appologize.
You do need to realize that on 100% of the cars that we have done aftermarket cats, they are all different. Cars do not react the same way. Even on the Supersprint full bolt-on solution, sometimes you get a SES sometimes you don't. WHY? I have no clue. I am sure it comes down to the electrical sensitivity in each car and the communication of the o2's - but there is really no way to predict these things. Crappy answer I know, but at least it is honest. It is better then just telling you it will fit 100% to try to get your money.
We have installed these cats on about 30-35 M3's and M5's. In addition, these cats will be used on our upcomming bolt on M3 cat system.
They are weld on for the M5 as they are universal cats. In order for them to be bolt on, you would need to jig up pipes, fabricate flanges, etc. etc. etc. This all equal more $. I can do a bolt-on piece for you for about $1500-1700. It will take 4 weeks and I need an M5 locally to jig from. We to this point had not seen the market, even with the known poor quality of the e39 cats.
Once again sorry that your conversation was less helpful then you had hoped, but this should help get you some answers.
