How to make stock exhaust louder

12033 Views 28 Replies 16 Participants Last post by  Wheelies420
Any ideas on how to make the stock exhaust louder on a 2013 ZX6R.
Can't afford aftermarket right now. So in the mean time, I would like to modify a stock exhaust.
Thanks in advance.

Take off the muffler and run just the prechamber. That'll definitely make it louder!

Shorten it and remove the baffles maybe... Or just save your money and buy aftermarket when you can afford it. I have everything stock for my bike in the attic, so when I go to sell it I can return it to stock and sell the aftermarket parts.

If you mess with it and don't have the money for a tune up - it isn't worth it regardless. There is more science involved in the stock exhaust than you think - vibrations and other outputs are controlled by the exhaust and lesson the impact on the motor. If you don't have the money for a slip-on, I wouldn't waste your time potentially lessening the life of your bike.

If I could source this I would, but this is coming from an instructor of mine who I've talked with about mechanics and how modern sport bikes have been built. Do what you want regardless, I'm just putting my .02 out there

Think of an exhaust system as a musical instrument like a trombone or trumpet. Messing with the length of exhaust tubing and tubing size messes with the "tone and pressure." Motors are tuned to work specifically with the exhaust they are paired with. Changing lengths and pressures messes with the back pressure and timing of pressure changes in the exhaust system. Every time exhaust is output, there is a small suction created outside the exhaust that sucks air back in slighty. Disturbing this balance can over time damage valves, etc. Just something to think about.
If I go with an aftermarket exhaust do i need to get it tuned.
This is my first Motorcycle so I'm learning.
I know cars but not bikes...LOL
To get all your moneys worth when you purchase exhaust you should have it tuned. If you really want to get all your moneys worth and the best performance just set aside another $1,000 bucks for mods. By the time you buy exhaust, free flowing air filter, and a power commander and get it tuned your looking at a minimum of another grand. Thats why I am running stock exhaust because its just not worth another grand in mods. Just my opinion of course.

I see your in Kent WA. I live in Rochester WA we should meet up and ride some time.

These guys are full of shit :roll:

You don't need to get it tuned after you put a new exhaust on! If all you're doing is a slip-on exhaust (which I'm assuming is the case based on the budget), your bike will be just fine to start up and ride away without ever looking back as soon as you get it bolted up. If you change too much about the airflow of the bike, like a full exhaust, air filter, etc. then you might want to, but not just with a different slip-on exhaust

Save up the money and buy a slip-on and enjoy the beautiful sounds - you won't regret it! :bigthumb:

If your on a budget look at danmoto Gp1. Cheap as chips looks nice sounds nice and very lite. Great value for money.
unless your getting a full system you wont need a tune. The cat is the main reaction in the exhaust that effects the Motors performance. Along as you don't knock it out you'll be fine.
Just installed my Hotbodies MGP slip-on the other day and the bike runs and sounds amazing with no tune whatsoever. Just tied off the stock servo cables and she was good to go. It only cost $250 on Amazon and looks and sounds incredible to me...

Glad your exhaust worked out for your but you know what they say about opinions.

I do...and this video expresses a stupid-ass opinion :coocoo

Are you honestly going around telling everyone you know or encounter who owns a "bone stock bike" that they really need to go drop the cash to get it dyno tuned?! That's completely asinine! I understand what the video is saying, but that's just dumb :roll:

I dont think that a new bike should be dyno tuned by any means but that being said if your paying to modify your bike you are probably looking to get the best performance out of it. If I am going to spend the money to make my bike perform at its best I would want to get the best bang for my buck. I would buy the exhaust, filter, power commander, and have it tuned. If all you care about is sound then throw a slip on it and have at it.

That's you... If all you put on is a slip-on, you don't need a tune. Hell, a tune would be an absolute waste of money in that situation.

I think you're making two mistakes here:

1) If you're looking to increase performance, a slip-on exhaust is not the way to go anyway.

2) I don't think most people putting a slip-on exhaust on their bikes are looking to increase power - they are looking for a better look or a better sound (or both).

If you are doing it for performance, then you'll want a tune, but then you'll also want a full exhaust (not slip-on) and an AM fuel controller and and and...that's not what we're talking about

As I said before I was attacked for an opinion, if all you want is sound then throw a slip on and have at it!

:2fingerlol:

My offer still stands to go riding if you are interested. I know of some great twisty back country roads in my neck of the woods. Just as long as you are not an opionated prick that likes to attack people with a difference in opinion. I just like to ride and am always looking to more people to go with.

Seriously man? Nobody attacked you for anything! Find one place where I said anything about you as a person...I didn't and I won't because I don't know you. I never attacked you and I don't intend to. If I were calling you names and saying you're an idiot and making rude comments about your mother, that would be attacking you...again, I didn't, and won't, do that.

I expressed a difference of opinion on a motorcycle-related topic - that's not me attacking you. I may have attacked your opinion because I think your opinion is kinda dumb, but that's what's so great about opinions, we don't have to agree ESPECIALLY on something as trivial as this! I'm sure there are people who, if geography were a bit different, I could be quite good friends with who disagree with me on this. That doesn't mean I wouldn't be friends with them, though.

As stated, I didn't, and don't plan to, attack you - maybe your opinions now and then, but let's separate that from me attacking you. Also, if you notice, the only truly mean things I said about any opinions were about the opinions expressed in the video. Now, if you happen to agree with everything in that video, I guess I was attacking your opinions as well, but it was aimed at the video. And lastly, I hope you don't take this post as me attacking you either, but if you decide to anyway, I'm sorry you feel that way. I get a little annoyed when people insinuate accusations against me for things I haven't actually done. Have a great rest of your day
:cheers


Edit: OP, sorry for jacking your thread....not real sorry, but at least enough to go back and type this apology :O
See less See more
:laugh

Keep em right side up and stay safe everyone!!!!

:cheers
