any opinions about all of these on sound, loudness and quality would be greatly appreciated, I like the deepness of the
2 bros but I am open to other possibilities even yoshi. need bang and a lil buck thats why I haven't jumped on the 2 bros yet ooops i meant m4 (typing on a laptop in the dark=typos lol.)

if it matters its for an f4i

 

ive got the 2bros c2 carbon bolt on for my 929. absolutely love it. dont know if its the most powerful, but i think it sounds the best of the pipes that ive heard. its a little on the loud side. but a good, deep loud at low rpm's and indy car scream at the rev limiter. and the carbon fiber pattern looks better (imo) than the norm. the lonly jardine's that ive heard were on a rc51, a heard a hindle on a 900rr (almost d&d loud) and ive only seen m4. never heard one but alot of the magazines say that they are good.

 

i had an m4 on my bike before i changed it out with my yoshi trs. really nice pipe and didnt cost an arm and a leg. only reason i replaced it was i dropped it and the can and midpipe got all scratched up.

 

jardine iMO

 

Nine to nine,this is petty much off topic but that is one funny *** icon picture "Ill hit it"where would i go about getting something like that?

 

i just did a search on animated avatars. looked through alot of pages and found it.

 

yeah I went with jardine and I am very pleased especially for the money
