I used the "Search" feature to see if Coffman's Exhaust Tip (slip-ons) had gained any popularity among Hayabusa owners but only found a thread that was littered with a wide variety of opinions ranging from those who loved the sound and price point to those who equated such with $30 exhaust tips from auto zone?....LOL!...well here's my opinion on things after owning a Kaw ZRX1100R that I brought from bone stock too Stage III with a 4:1 full exhaust muzzy megaphone to my FZ1 dyno-tuned with Ivan's Jet Kit and making 136rwhp through a full Yosh exhaust and of course my Hayabusa which I equipped with a BMC (Race) Air Filter, PCIIIUSB and Full Akropovic Exhaust where I had Ken Wheeler Dyno-Tune the A/F ratios adding some fine touches to Ivan's Map and now?...years later I find myself with a hot mess of a used '08 ZX-14 that came equipped with Coffman's Exhaust Tip (sans the baffle cores) so here's my hindsight take on all things exhaust related....
After having purchased, installed and experienced the effects of full system exhausts on my ZRX, FZ1 and Hayabusa?...I knew that no matter what bike I garaged next?...that I would be opting for slip-on's (over full exhaust systems) and here's why...
Prefaced with: Top Speed Runs (Think Bonneville), 1/4 Mile Dragstrips & Dyno Night Shootouts and all associated bragging rights aside?....
When I look back and speaking as an all around street-bike rider and lover of mountain twisties?...I find myself wishing I had opted for slip-on's instead of full exhaust systems because once the engines inhale was opened up with thin oiled gauze race air filters and the exhale was opened up with full system headers?...all that happened was horsepower was increased in the far north regions of my tachometer but came at the cost of low-end torque or more eloquently put?...
"Much of the goodness I regularly used got moved too a place I rarely had reason to venture too."
Now don't get me wrong here as I definitely had more than my fair share of fun with full system exhaust from top speed runs in safe and controlled area's too reeling in competitors in the final yards of the Outlaw Drags (in Deland, FL) but these events made up but a fraction of a single percent of the riding I did and still do therefore?...while I did my best to look for a bone stock Hayabusa (or just slip-ons)?...I wound up with a ZX-14R with just slip-on's and in this case it was Coffman's Exhaust tips and now I'll just shamelessly copy and paste what I posted in a FB community and make no mistake folks...Coffman's isn't just $30 exhaust tips from auto zone and I'm quite impressed at how much sound suppression Gary Coffman has managed to harness is such light, short exhaust tips where the benefits one gains are...
1. Great sound for 1/3rd-1/2 the cost of a full system.
2. No loss of low end torque but?...
3. A huge loss of Dual Stock Canister & Mid-Pipe Weight! (we're talking approx. a 40-60lb weight savings here which in and of itself is the equivalent of about 10 extra ponies!)
I knew nothing of Coffman's prior to receiving such on my latest purchase but I can now divulge with confidence that Coffman's rox even when mine were a bit beat up as follows...
It's often times a multitude of "Little Things" that build up over time which causes folks to start thinking about selling their bikes...I know that was the case for me when I regretfully decided to sell my beloved Hayabusa after 8 years of ownership where it needed a complete freshening up from tires too suspension too new chain & sprockets and in a weak moment?...I made the mistake of listing it "For Sale" and what a sad day it was when I waived goodbye too Oren Ishii as she rolled away on someone else's trailer and now?...now I bought somebody else's hot mess of a '08 ZX-14R and despite it having a new set of Pirelli's on it?...I already changed the oil that looked like black ink...and for $150 I replaced the gauge cluster do to a bleeding LCD...washed, waxed and did the chain maintenance thing and then?...Then I called Coffman's so I could order up two new baffle cores for the loud azz Coffman Shorty slip-ons that were on this bike and in the process?...I asked Pam Coffman if she'd be kind enough to send me a new "Coffman's Badge" for the left side exhaust where the previous knucklehead had pretty much beat it in half with a miss-adjusted aftermarket kickstand (with no kick stand spacer added) and she did and this morning?...I addressed that by removing the old rivets...warming up the pipe and hitting it with some VHT ceramic header paint and then mounting up the new Coffman's Badge and I think I did a bang up job if I do say so myself! But this hot mess of a ZX-14 is coming back together very nicely and I love the power it regained in the low-end by replacing the baffles!
