looking to hear Eisenmann/Challenge Sport HFC setup

rubyM3 · 04-13-2014, 10:55 AM

Looking to purchase Eisenmann Exhaust black series but unsure what setup to go with. Debating between Sport v. Race with Challenge Sport hfc x pipe.

Worried that race will be to much drone and problems with the law.

please advise.

thanks in advance.

I have the race only no x pipe or hfc and I think it's perfect once broken in its a lil on the loud side at first. It does drone (like any other "loud" exhaust) but turn the radio up a lil (you won't need to blast it) and I don't notice I was worried about the drone and loudness before I bought mine too. I was advised sport was better with hfc x pipe though
