Choosing the Right Exhaust

Recommended Posts

tuninghq
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.
 
We are your FZ-07 exhaust supporting vendor! 
For anyone looking to purchase an exhaust, drop me a PM or give us a call at Dobeck Performance. 1.877.764.3337
All exhausts include free shipping within the continental US.
We will provide the best possible pricing. If you find a lower price, let us know!
 
We have done dyno testing on the following exhausts brands:

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.

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!

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.

Mine pops when up-shifting. Usually only between 1st-2nd and 2nd-3rd gear. 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?

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.

Ha, ha! 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!  >:D

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!
