This is my review of the Yamamods 2" power tip for the 2007-2009 Grizzly 700.
Discription from their website. yamamods.com
THIS IS A POWER TIP FOR THE YAMAHA GRIZZLY 700 WITH FUEL INJECTION. FITS YEARS 2007, 2008 AND 2009. IT IS A 2" STAINLESS STEEL EXHAUST MOD / ENDCAP. IT REPLACES THE ORIGINAL RESTRICTIVE 1" TIP AND SPARK ARRESTOR TO A FULL 2" TAILPIPE. IT HAS A 45 DEGREE DOWN TURNED ANGLE TO DIRECT EXHAUST AWAY FROM THE PLASTIC. THE SPARK ARRESTOR WILL BE ELIMINATED WITH THIS MOD.
A STAINLESS STEEL FLANGE NEAR 1/8 THICK, IS PRECISION LASER CUT AND PROFESSIONALLY TIG WELDED FOR A PERFECT SEAL. THIS MOD WILL HELP LOW END POWER. WHEN INSTALLED IT PRODUCES A NICE THROATY SOUND LIKE A 700 SHOULD. IT IS NOT MUCH LOUDER THAN STOCK IT JUST PRODUCES A DEEPER TONE.
Nicely TIG welded.
I bought it with the intention of painting with High temp black paint and keeping it looking stock.The Yamamods tip sounds very nice. The Grizzly has a louder growl to it on idle and roars more at WOT. Cruising speed it has a nice mellow even sound to it.
I wish it came with removable spark arrestor so that I'm legal in state parks... or anywhere for that matter.
As for power increase... I did not notice any by the seat of my pants.
This is for those of you that don't like the stock sound and want to hear a more aggressive but not obnoxious sound from your Grizzly.
If you need a tip with a spark arrestor, look at the tip made by 2R Racing.
