Gen 2 Exhaust

[oediehl]

Just bought an '09. Not really looking for more power, just a somewhat throatier exhaust (not crazy loud). I was hoping I could just drill out a baffle or the like, but from what I've heard it sounds like that's not an option. Don't really have the budget for something like an Akrapovic; anybody have any experience with the
Maxflow TwinStar 4-2 Dual Cat Eliminator
setup? It's a more modest $600 deal on ebay

That includes the mufflers I believe which will be real LOUD.

This pipe will allow you to use the stock mufflers:

This pipe will be fine but there are 1 or 2 other options out there besides the Akra (X-Pipe for one)........I need to do a little research to refresh my memory.

Thanks. I also found a Delkevic system that appears to eliminate the cat: https://www.amazon.com/Yamaha-Slash-Round-Stainless-Exhaust/dp/B0773CRKB4

That also includes the mufflers.....there are a lot more options if you don't want to keep the stock mufflers. Delkevic is one and by far the lowest cost.

I wanted to keep the existing mufflers and remove the cat for more exhaust sound. I ended up buying the Doninator Y pipes from Poland, by far the cheapest solution to replace the cat at $350 all in. I also inserted baffles in the existing mufflers as the sound was too loud for me.

Yes, the existing mufflers are straight through exhausts and for me were too loud but the Delkevics probably come with removable baffles. I wanted to keep the look of the existing exhausts.

There was a Youtube video of two Gen2's, one with cat removed and one as standard which gave a good sound comparison of the two, but can't find it so have linked another video which has standard mufflers and cat removed so that you can hear the "improved" sound

Sounds good. But since a Delkevic tri-oval de-cat system was about the same price as just the x-pipe style under-body setup, I ordered the Delkevic. We'll see.

That will be much louder.

They tell me that the 17" canister would not be dramatically louder than stock (whereas a shorter canister would be). I'll be finding out soon.

Wouldn't bother me, I like loud.

A longer can produces a deeper tone normally and a little quieter. I know someone that just installed a Delkevic and it is much louder than the stock cans but sounds good. It is a shorter can though.

Delkevic system.....with short cans.

Here's a link to hear the sound on my bike. 14" Carbon Delkevic's with the de-cat mid pipes. I like it, not super loud at steady throttle when cruising but they growl when getting on it.

Sounds good and not real loud.

 

[user 16790]

it's loud if you play the video through your hi-fi system

 

[GreggyG]

Are there any good videos on how to remove the cat?

Akropovic has a step by step guide(not a video) on their website.
