Yoshimura Titanium Alpha & Full Exhsus

[adamkhan]

I installed/ modified an extra Yoshimura Alpha Slip-on I had for my sons H2SX connected to S1000R headers. It looks, fits & sounds great. Had to cut the Y pipes because the difference in outlet & inlet diameters but it worked out just right. My stock muffler was de-restricted; the baffles were punched out so it was loud. The Yoshimura is about as loud but has a deeper bass , much freer flow. I can feel it has more power throughout the Rev range. I'll be installing a Carbon Fiber Alpha muffler soon to try and quiet it just a little. Also will try a Scorpion as soon as I make that deal.

Interested in the outcome to see which is quietest vs stock muffler. I'm really debating it now that my stock muffler is falling apart.

Ant, my stock one had the baffles punched out so it was loud. I'll be trying a couple of other mufflers later. Will update on the results.

Not sure what you mean about baffles punched out, OEM can is straight thru

What’s the plan for the fuelling?

I still have my stock O2 sensors so it'll self tune. I am planning on getting the Brent Tune flash done in the future for around $700 including the flash loader tool. Dyno tuning cost is over $1000!

sheesh where you looking at those dyno tuning prices? Maybe it's one of those UK US things but here it's about 400 quid for a dyno tune and 6-700 for the brentune

Stock muffler doesn't have any baffles as such, they're "straight through" and loud AF with proper headers. If you hold it up to the light, you can see straight through it...and as mentioned many times, on the Gen-1...most of the "mufflering" is done in the cats. You can basically run the stock headers without the muffler and it will not sound much different.

Smithy.

Did not know that. Mine looks like there was a block-off plate that was punched through.Maybe I was just expecting that was the case from how loud it was.
