Tune? CEL?

Your X5M sounds great!

I was wondering if you have done a tune yet or is still the stock tune?

If it is the stock tune, have the catted DP's thrown a CEL (check engine light)?

Nice! If I'm not mistaken I think this is the only company offering high flow replacement cats with the DP's? Or at least at a reasonable price.

One more question. I don't know if you will be able to answer this, but the one concern I can see with Ultimate Racing's DP's are that they do not have a flex point in their DP's. All other manufacturers that I have seen have a flexible section of their DP which allows the motor to torque without stressing the DP's. I am concerned that over time the welds or the pipe would crack from stress :-/ Have you noticed any leaks from the DP's?

Have sold quite a few of these along with our software packages and no issues so far. Performance is fine and obviously sound is the same. Let me know if you have any questions. Regarding the stress I think you would need a few years for this to show up but once again I do not see it being an issue.
