Hello Everyone,

I recently installed the above and have tons of raspiness and drone from 2K to 5K rpms. Has anyone had a similar experience? Thank You in advance.

You installed the full m5 exhaust or just the mufflers? If you installed just the mufflers do you still have your stock resonators on there?

Hi simple I installed the full exhaust....

Do you have the vacuum lines connected? I think your drone is coming from the catted hi-flow dps... you can probably get a couple of vibrant bottle resonators to replace the stock ones to handle that drone...

Is the full M5 exhaust install a straight fit, no mods/cutting? I have a local guy offering me his for $500, no cuts.
Was thinking about getting the catted ARs as well but this is certainly concerning.
