I'm about to buy two brothers exhaust for 2005 F4i and notice a size difference between the M2 and M5? Do you guys recommend the M2 or M5 since bike is only 600cc and why?

 

as long as they are both for the f4i it doesnt matter... im just sure one sounds a little different than the other....

 

Which ever one is bigger because i have no idea which is which but the bigger on looks funny on an f4i. It's not very pretty in my opinion. You have this huge can with what looks to a really tiny midpipe. Looks silly. I would get the smaller on but that's just my opinion. Good luck on your choice.

 

ive got the m-2 and im in love with it. i think its my favorite thing ive purchased for my bike thus far. sounds deep and throaty, just what i was looking for

 

oh how i hate two bros lol

 

i agree with pacfoo. i have the m-2 shorty and i get compliments everywhere i go about the look and sound of it

 

I'd recommend the M2. I've got it on my bike and it looks like a great fit for the bike and sounds phenomenal.

 

Thanks fellas for the comments, recommendations, & pics. I went to CycleGear to view the exhaust 1st hand and did some research and I'm gonna get the M2. Website also said there isn't a sound or performance difference between the two can even though the size difference. The main reason I decided to get aftermarket exhaust was because I hate the size if the stock can so IMO smaller is better.

 

Ya this one is probably your best bet. Looks great on your bike by the way! I have a two brothers on my CRF 50, haha.

 

I'm lookin at the chrome m2 for my 01 f4i----does the midpipe seem a little bit too long or is it just me?
