FigJam-OhNine Posted June 3, 2015 Share Posted June 3, 2015 Well, after some humming and hawing, I've decided to throw my credit card at an Arrow! I called 2 Wheel Dynoworks to talk about Arrow vs Two Brothers, and they helped make my decision. Their main argument is that the Arrow has one tune. Baffle in our out, it doesn't matter. Same tune. Two Brothers has different tunes for bare pipe, 4dB reducer, 7dB reducer, spark reducer, etc... any accessory requires a different tune. Also, according to them, the best improvement with Two Brothers is bare pipe, adding the 4dB reducer gives some gain, anything more than that and you can actually lose HP from stock. They couldn't shut up about their praise for Arrow, so I'm going to go with that. Once it's on, I'm taking a trip to get the ECU flashed in person. Coming from Italy, so it will be a few weeks, but I got the full system with racing collector and the Dark Aluminum slip on with Carby end cap. I ordered from Bayside Performance in Vancouver, BC, which is great because they're Canadian like me!

mechnic13 Posted June 3, 2015 Share Posted June 3, 2015 Im running TwoBrothers with the 7db insert . I can tell Ive lost a bit of torque from a dead stop , but the motor now rips thru the RPM range so much easier than the stock pipe . My butt dyno tells me its a big improvement . Savin some more dollars for the ECU reflash at this time Link to comment Share on other sites More sharing options...

If you can live with that volume level, you'll get good gains post flash. Link to comment Share on other sites More sharing options...

mechnic13 Posted June 4, 2015 Share Posted June 4, 2015 I would love to remove the DB killer all together , but I dont think my neighbors would appreciate it as I leave for work at 5:15 am daily . The TwoBrothers system with the 7DB insert is right at the limit for tolerable noise to myself , neighbors , law enforecment . Link to comment Share on other sites More sharing options...
FigJam-OhNine Posted June 10, 2015 Author Share Posted June 10, 2015 The waiting is the hardest part... ...but... while I'm waiting... Can anyone tell me if there are any issues I can expect in the period of time between installing my new Arrow exhaust and riding down to @2wheeldynoworks to get my ECU flashed? Is it better to leave the DB killer (baffle) in before it's flashed or does it matter? I know I'll probably get some popping and fire before it's flashed, but as long as it doesn't cause any harm or discolour the pipes I can live with that in the short term.

Luckily there's a product out there that does that Link to comment Share on other sites More sharing options...
rx2ride Posted June 15, 2015 Share Posted June 15, 2015 Looking forward to the review of the arrow and ECU flash. Nels did my Ecu already, now time for exhaust. Do you loose your center stand with the Areow? Link to comment Share on other sites More sharing options...
Premium Member rusty_spoke Posted June 16, 2015 Premium Member Share Posted June 16, 2015 You can keep the stand, I posted pics here http://fj-09.org/thread/781/arrow-on Link to comment Share on other sites More sharing options...
rx2ride Posted June 21, 2015 Share Posted June 21, 2015 Sweet! Now I know what exhaust to get. Just need to decide white or black... and how to hide yet another bike part purchase from the wife :-0 Link to comment Share on other sites More sharing options...
FigJam-OhNine Posted July 2, 2015 Author Share Posted July 2, 2015 The slip on has been sitting at Bayside Performance for two weeks, but they're still waiting on the collector. Ugh... A month and counting. They'll get me a status update on Monday. Link to comment Share on other sites More sharing options...
lapuree Posted July 3, 2015 Share Posted July 3, 2015 BTW, I was wondering: is that a necessity to replace the collector as well? I had Arrows exhausts on my Street Triple and liked the sound ver much but at the time, it was only the slipons, no collector change. Link to comment Share on other sites More sharing options...

I had Arrows exhausts on my Street Triple and liked the sound ver much but at the time, it was only the slipons, no collector change. Necessity? No. Added benefit? Yes. Most of the added HP of an after market exhaust is with a full system change. A slip on is mainly just paying money for sound. Plus, it's not plug and play. You have to surgically remove the catalytic converter to add a slip on to the FJ and for most slipons, you have to remove the center stand if you want to go that route. The cat is welded on. Either way, it's already paid for. Just delayed. Link to comment Share on other sites More sharing options...

FigJam-OhNine Posted July 14, 2015 Author Share Posted July 14, 2015 Arrow exhaust arrived yesterday. Installing it was a tedious exercise in lining up all the pieces of the collector properly. I don't have a picture yet, but that will come soon. Looks good though. I can't decide if I'll ride with the baffle in or out. It's definitely loud without it. The high end is about the same, but the low end bassy rumble reverberates through the helmet like crazy without it. I may end up using it, but I don't want a performance drop. I'm hoping to head to 2Wheel Dynoworks this weekend to have my ECU flashed, and I'm sure they can lend some insight into the performance differences with the baffle in/out.
