tuninghq Posted September 14, 2015 Share Posted September 14, 2015 I'm creating this thread for forum members to share their experience with the various exhausts so others can choose what exhaust will be best for them. Post what features are important to you and I will get back to you with my recommendation. Sound, weight, performance, price, etc. Hopefully this thread turns into a great buyers guide for forum members. It would be great if members shared their video clips of exhaust sound, settings and results for various exhausts, weight specs of exhaust and installation tips.

pattonme Posted September 16, 2015 Share Posted September 16, 2015 I realize it'll become a long first post with repeated edits, but if you (@tuninghq) could put all the relevant data in a table and/or billeted list (see for example the Fork Upgrades and Compat Swap thread for ideas) that would probably be welcome. How's this as an example? Then again, it might be easier to maintain a real spreadsheet, host it on dropbox/website/S3 and periodically do an export into a graphic for inclusion.

Premium Member ratlab Posted September 22, 2015 Premium Member Share Posted September 22, 2015 i don't know if this has been covered,but the dyno results of euro MT07 are about 10 hp higher with the same packages- EX: akra ti-dna,pcv5-63 hp in u.s.-72 in g.b.do you know why?

Bucaro_FZ07 Posted September 22, 2015 Share Posted September 22, 2015 Hey @ratlab I guess is because they might be measured on a different standard system, it can be based on British or Italian or any other system https://en.wikipedia.org/wiki/Horsepower Link to comment Share on other sites More sharing options...
Beemer Posted September 22, 2015 Share Posted September 22, 2015 I recently read somewhere that excessive air is what causes the popping from exhausts. With my EJK I've been cutting back on the accelerator fuel to reduce the popping but not having much luck. It appears that after reading about excessive air (if it's true) that I should've been increasing my accelerator fuel to match the extra amount of air from using an K&N air filter, un-snorkled. I haven't tried adding fuel yet myself. Does that sound right to you or what are your recommendations to reduce popping, whether it be popping on decel or between upshifts - if there's a difference? Thank you! Beemer Link to comment Share on other sites More sharing options...
tuninghq Posted September 22, 2015 Author Share Posted September 22, 2015 Decel popping is typically a different condition than upshift popping. Adjusting the accel pump is not going to have much effect on decel popping as the accel pump only comes on for a quick second anytime the throttle is opened. It helps with throttle crispness & response. To reduce decel popping, we recommend increasing the green adjustment mode as decel pop is typically a lean condition. We also suggest having the baffle in as this will increase back pressure and reduce the amount of fresh air getting sucked back up the exhaust which will cause decel pop. If you are getting upshift pop, this is typically a rich condition; we have found decreasing the yellow fuel zone helps eliminate this condition. When making adjustments to the EJK, we always recommend making small incremental adjustments at a time. Don't make a huge jump in settings at once. Let us know if there is any other questions. -TuningHQ Link to comment Share on other sites More sharing options...

I have done just that, decreased my yellow fuel zone as much as I could before it started acting like it wan't getting enough gas so I bumped it back up .50. Even though the popping has decreased it hasn't been totally eliminated. Is there anything else to be done to decrease the popping? Can hotter/premium spark plugs or adding more air to the fuel help even to eliminate popping if the EJK can't adjust out all the popping? Anyone? Any ideas?

pattonme Posted September 23, 2015 Share Posted September 23, 2015 ear plugs. and a faster acting ankle. Hey, you asked for *any* ideas. Too lean can also mean incomplete burn -> residual. Are we talking burble or bang? Does it happen on any 1-2, 2-3 or just after you've been idling for 20+ seconds? I'm guessing it only happens when you start off from a stop? In which case idle mixture isn't right so you get a build-up which gets ignited when the exhaust gets hotter (on the throttle) when resuming forward progress.

That's funny but I've got that topped. [attachment id=955" thumbnail="1] Ha! Thanks, but I already figured it was excess fuel not being ignited so again, what can be done to eliminate it? Hotter plugs like I mentioned that might burn fuel more efficiently or anything else other than ear plugs? I put a whole bag of ear plugs in the exhaust but they wouldn't stay in so that idea didn't work very well, damn-it! Beemer Link to comment Share on other sites More sharing options...
Beemer Posted September 24, 2015 Share Posted September 24, 2015 These are my EJK settings: G 4, Y 5, R 4, GB 2, YB 3.5, RB 1. If you've never heard an Akrapovic carbon exhaust before and would like to hear one on an FZ-07 here ya go!

pattonme Posted September 24, 2015 Share Posted September 24, 2015 Not hearing the popping. I hear what sounds like a mechanical flapping at the very end of each blip but that's probably normal. Link to comment Share on other sites More sharing options...
tuninghq Posted September 24, 2015 Author Share Posted September 24, 2015 @Beemer, Try raising the yellow setting back up to 6.5 and then maybe go slightly richer to see if that helps. If that doesn't do anything for you, then I would double check for intake or exhaust leaks just to make sure. Let me know what you find after that. What intake mods have you done? -TuningHQ Link to comment Share on other sites More sharing options...
Beemer Posted September 24, 2015 Share Posted September 24, 2015 Roger that! Thanks! When I originally installed my exhaust I did check for leaks and didn't find any but I may have missed finding a leak. I used smoke around the pipe to check for disturbances in the smoke but found none. Is there a better/easier method for doing leak checks in an exhaust system? I never felt confident with the one I tried. The only mods I've done toward engine performance are the Akra carbon pipe, the EJK and an un-snorkled K&N air filter.

Beemer Posted September 24, 2015 Share Posted September 24, 2015 Just got back from a ride. I went back to 6.5 and as expected, it had some popping between shifts so I set it to yellow 7 and it popped less but not to my satisfaction. I then set it higher to 7.5 and only heard a few pops within an hours ride. It didn't seem to affect the gas mileage either. @ 35 mph in top gear it still shows 94.5 mpg. Ka-chow! Thank you tuninghq, that seems to have done the trick! I'm still curious about another way to check for exhaust leaks. Beemer Link to comment Share on other sites More sharing options...
