mcrenzo Posted August 4, 2014 Report Share Posted August 4, 2014 I want to upgrade my exhaust and I’m thinking of getting the Yoshimura RS5 slip-on at http://4wheelonline.com since the price is within my budget. Just wondering if Yoshi is really a good exhaust. Or is there a better one that doesn’t cost too much. I heard that Akrapovic is a good choice but it has a deep tone. Is this true? Thanks.

MidgetTodd Posted August 4, 2014 Report Share Posted August 4, 2014 Akro is deeper yes. Yoshi is good too. If you are just doing a slip on you won't gain anything but a diff sound. If it's gains you are wanting you'll need to add a filter and power commander then get it tuned by DynoBrian. The slip on is a good start though.

CeeBeeArr600 Posted August 4, 2014 Report Share Posted August 4, 2014 I have an RS5 on my cbr. I like it. Its not to loud down low, but when you get on it gets pretty loud to me at least.Sent from my SCH-I535 using Tapatalk Quote Link to comment Share on other sites More sharing options...
banditj13 Posted August 4, 2014 Report Share Posted August 4, 2014 Just stay away from Two Brothers, just loud plain loud. No gains eitherSo true! I am running a two brothers slip on right now (it came on the bike), and it is nearly unbearably loud at speed. Quote Link to comment Share on other sites More sharing options...
SJC1000rr Posted August 4, 2014 Report Share Posted August 4, 2014 As noted by everyone else, a slip on will only change the tone of the exhaust. If you're looking to dive deeper into things, don't get a power commander....get a bazzaz Z-Fi. I've worked with Brian when I raced my 600rr and he enjoyed the bazzaz much more since it controls all 8 injectors. I had a PC3, and sold it soon after for the bazzaz. An aftermarket air filter won't gain much vs stock on a street level either. A race filter may gain a minor amount, but it's not worth the risk of allowing more particles into the engine.As for exhaust brands, here are my suggestions:Leo VinceArrowAkro Quote Link to comment Share on other sites More sharing options...
bloodninja420 Posted August 4, 2014 Report Share Posted August 4, 2014 What year CBR? In my opinion some of the older models sound pretty damn good stock, but it's all personal preference. Quote Link to comment Share on other sites More sharing options...

And I run the Leo Vince on my 1000rr street bike. I have the Akro on my GSXR600 track bike. My comment on gains wasn't to mean you'll see huge gains from a filter, but that to see any real gains from an exhaust it's needs to be a full system with filter and fuel management, not just a slip on. I suggested Power Commander because he said he was on a budget and those can be picked up for 150. I run the PC on my RR as it's street and just exhaust and filter with smog removal. I put Bazzaz on the GSXR because it's track and Bazzaz has QS and TC all in one box. Brian tunes all mine too, he likes Bazzaz because he's anal & picky lol. You do get control of all 8 with Bazzaz and PC now has an add on box that gives control of all 8 also but in reality you don't need control of the secondary injectors unless you have a highly modded motor or are a perfectionist like Brian lol. But I guess that's why I only let him touch my tunes lol Quote Link to comment Share on other sites More sharing options...
redkow97 Posted August 4, 2014 Report Share Posted August 4, 2014 I had a full Arata titanium system on my 600RR. The only difference mechanically between yours and mine would be the fuel injection changed mildly in 2005. Anyway, I thought it sounded good, but the bigger deal was that the titanium weighed a TON less than the stock setup. Quote Link to comment Share on other sites More sharing options...
jbot Posted August 4, 2014 Report Share Posted August 4, 2014 only if they're cheap or if they came with the bike. otherwise, not worth it unless you're using it to shed some weight on a race bike and to gain a few horsies to keep up with the triumphs and R6's on the track. 675 is bestseventyfive Quote Link to comment Share on other sites More sharing options...

Gixxus Christ! Posted August 5, 2014 Report Share Posted August 5, 2014 Yosh pipe sounds good, even with the db killer installed. I have an rs3 on my 1200 bandit...it's reasonable at idle and low throttle but without db killer it barks pretty loudly when you twist the happy-maker.

mcrenzo Posted August 5, 2014 Author Report Share Posted August 5, 2014 I want something loud but not harsh and I'm not expecting any power gain using a slip-on. Looks like Yoshi is a good exhaust for my 06 cbr600. Thanks for the reply guys! Quote Link to comment Share on other sites More sharing options...

Heagachongoose Posted August 15, 2014 Report Share Posted August 15, 2014 I had a yoshi rs-3 on my old ex500. That thing purred like a kitten. Wasn't loud but it definitely wasn't quiet. Very nice full warm tone to it. I liked it. Never heard an rs-3 on a 4 banger though so I can't really comment there. Honestly I feel like you'd be happy with just about any slip on that isn't complete shit as long as a difference in sound is all your going for.
