Bang for the buck...

   You have limited funds, but want to do some exhaust work. what's the best bang for the buck... buying a new header or a new muffler?

 Very clean. Did you gain any performance from that mod?

 I should have clarified... if you're looking for performance, but of limited funds where's the best place to spend the money... header or muffler?

   (I tend to be all about performance of one type or another)

Yes it does feel a lot more flickable, as I have lost +6 kg of weight  :38:

Also my bum-o-meter registers a bit more quickness in the low to midrange - but I did fit a BoosterPlug at about the same time  :027:

Steve - For my next cheap mod I'm looking at just cutting the Catalytic converter out of the system and joining the OEM headers and Toaster box back up together, keeping the same small outlet pipe arrangement as above  :756:

Like I did on my Mk1 2009 V650, where I also Gutted the Cat out of the underbody box - Details HERE FYI  :7:

    I have some dyno charts that would indicate not much to be gained by doing that. I'll post some charts up in a bit, maybe it will help dispel some rumors and start some new ones.  :007:

 Here's a couple charts to consider. The first is stock vs stock with a tune. The next is Delkevic and Black widow headers, tuned, with the stock muffler. As you see the Delk header isn't that far ahead of just the tuned stock bike. stock was 114.36 hhp, and 115.18 for the delk header with the stock muffler.

  If you're gutting the cat or adding a decat link pipe, I'd expect it to be about the same as the delkevic header, which is a designed the same as a stock header without the cat.

  Clearly the Black Widow is the power winner, even with a stock muffler.

I like the idea of decat, less heat under the bike. Black widow sounds best choice and glad to see comparisons using stock muffler. Is that combo reasonably quite ?  At 65 Iím not into loud and annoying  anymore , just good riding. Don't need every last drop of HP at top end as I don't go there.

   I'm 61 in less than a month. Noise and sound of the exhaust don't impress me anymore. I don't like loud either. A header with the stock muffler is fine at regular riding throttle openings. louder than stock, but not offensive. it gets a bite to it with hard throttle applications. Nothing like the aftermarket slip ons though, which can be LOUD.
