I have a Stillen Headers and Berk HFCs on 09 370. Will the 3" exhaust fit, is it better to go with the 3"? How much to 78247 for each?

Interested in buying an exhaust from AAM. What kind of deal can we work out?

Hi Rob,

I am potentially going to buy your CBE and HFC but i just had a few questions before purchasing! I am slightly worried about getting a CEL with the cats, is this a valid concern? Also, I KNOW that the combination sounds incredible, i have seen several videos, but can you give me an estimate on gains?

Thanks a lot!

Rob,
Are your test pipes still available?

Rob thanks for the add !!. I am looking forward to getting my car to you and the guys at AAM in a few weeks around the 2nd week of April. Tim
