Looking @ changing it up a bit & getting a different exhaust - I have no more than 5k miles on the Eisenmann Sport w/ connecting pipes & Lemans tips & ~4K miles on the midpipes.
Sounds aggressive when you get on it w/o drone on the A Bahn unlike most race exhausts.
IMO the perfect setup - Need tune or Delete-R or you will have CEL.
Cars garaged for Winter w/ the system on if you'd like to hear it. I'll take it off once I have a buyer. Prefer not to ship though I do have the Challenge box & packaging.
