I'm currently riding a 2009 Sportster 1200 Custom with 1 3/4" straight pipes, stage 1 tune, and air cleaner. I haven't been able to find an answer about this through searching, but can anyone tell me what the pros and cons would be of swapping the exhaust out for the Vance & Hines Big Radius exhaust system?

Which exhaust would be louder?

How would the performance of the bike change?

Is it even worth changing the exhaust?

 

Obviously the straight pipes will be louder, but they'll also produce less power.

the VH pipes will still be plenty loud (IMO) produce a bit more power. Also they'll sound better, straight pipes dont have a baffle or anything to regulate exhaust gas flow so they are loud but sound terrible paired with poor performance because of the scavenging affect.

 

Thanks 2500.

Where is the power gain most noticeable, down low?

 

I ain't very technical so the difference as I understand is :-
Straight pipes - potato-potato
Big Radius - POTATO POTATO
