Cobra Slip-On Exhaust
What Cobra models are available?
Note: Cobra is no longer making these slip-ons for the EX250. If you want a pair, eBay is your best bet.
There are 2 kinds of slip-ons available: Cobra F1's and Cobra F1R's.
I have owned both and I recommend the the F1's since a) they look nicer, and b) they sound better.
The F1R's are way too loud and obnoxious (and this is coming from an 18 year-old male); I got a noise violation ticket for them. The F1's have a lot nicer tone, and of course they are still louder than stock :).
