Tom, the bike ran great today! I had another friend ride the bike today. He has an H2 & S3. His comments were " I can't believe the level of performance while maintaining such excellent low end drivability". I did a 50 ft wheelie today! I shifted into second & the wheel popped up again! We put a serious hurting on my clutch! It started slipping after the thrashing we gave it! The frictions, steels & springs are new. It just could not take the extra power. I have some springs that are 20% stiffer than stock that I am going to try. I also took some great outdoor pics of the bike today I need to send you. - Ed

Tom, it definitely pulls better than the dencos or spec 2's. I went for a ride this AM on some country roads. It pulls very well at high rpm. The power does not fall off like the other pipes. Everything you told me about them is true. I am very happy with them. They are well worth the money. - Ed

Hi Tom, I just wanted to say that I have been extremely happy with your pipes. I was shopping around for a set of pipes for my H2 when you started selling them. I wanted to replace my J&R Power Pipes with something more attractive. I had heard Ed Zunz rave about your pipes and I still hadn't made up my mind. Then I bought a bike that Ed was selling for a friend of his and it had no exhaust (Bill Wirges pipes were there, but broken and rusted). Now I had to make a decision...2 bikes and only 1 exhaust system, so I needed pipes right then. On Ed's recommendation, I ordered your pipes instead of the SpecII pipes I had been leaning towards (hey, they worked great on my RD400). Your price was not much more, and Ed said they worked much better than his SpecIIs, so what the hell, I'll give them a try, and you offered my money back if I didn't like them.

Two weeks later, I drive to Florida to pick up the H2 from Ed.

H1 Pipe review:

He immediately hands me the keys to 3 of his H1s. One with SpecII pipes, 1 with Denco's, and 1 with your pipes and tells me to compare them. He says he's tired of everyone saying that he's nuts, that a set of handmade pipes can't possibly be as good as what he is saying, and he want's my unbiased opinion. All three bikes are stock other than the pipes. I rode all three bikes over the course of the weekend that I was there. On the H1, I cannot, in all honesty, say what they would do on the top end. I didn't rev Ed's bikes over 8000...they weren't mine to take a chance on breaking. What I did notice is that your pipes came on at around 5500 and pulled stronger than the SpecIIs and the Dencos all the way to 8000 when I shifted. What I noticed even more was that the bike would pull from 2000-2500 without stuttering. I had never ridden an H1 that would accelerate from 2000 RPM...I didn't think it was possible. I couldn't just snap the throttle and go, but I could roll it on easy and it would go! The Denco's and the SpecII's wouldn't allow that until I was well over 2500. I found out on a ride to one of the State Parks near Ed's home, just how well behaved your pipes were at low RPM. I could tell throughout the ride that I was in a higher gear than Ed, but it wasn't until I came to a rolling stop, that I found out how well behaved it was at the bottom. We came to a stop sign and had to make a right. I slowed down to almost a crawl, dropped 1 gear, saw nothing coming, started to go and stalled the bike. Instead of being in 3rd and dropping to 2nd, I was in 4th and dropped to 3rd. At less than 10 MPH, no wonder it stalled. I found this out when I tried to restart. I then realized I had just ridden several miles at 20-25 MPH in 4th gear on an H1! No bucking, no snorting, no coughing. I wouldn't have believed it had I not been the one riding the bike. I rode Ed's other H1s over the course of the weekend, and none of the others would have even thought about performing like that at low RPM.

H2 Pipe review:

So I get my new H2 home and it has the J&R pipes on it because yours haven't arrived yet. The bike runs well, pulls strong from 6000, tries to wheelie (would rather spin the tire), and in general I have a lot of fun with it. Then your pipes finally arrive. I bolt them on, following your instructions for spacing things out, rejet my carbs on the rich side, again following your instructions, and fire it up. Once I get the jetting closer to what it should be, I notice a performance increase on the top over the J&R pipes. Bottom is ok, but at 3500-4500, the bike is a bit rough. One more jet change, and all hell breaks loose. The bike is pulling well from just off idle, midrange is smooth and strong, and at 5000, things start happening. At 6000, the bike just jumps and goes. I can feel it starting at 5000, it gets quite a bit stronger at 5500, and at 6000, hang on to 8500, shift, hang on, shift, etc. This is on a stock motor other than a .040 overbore.

All I can say is that I love the pipes that you make. You'll be getting an order for a set of pipes for my H1 to replace the rusty stock pipes that are on it now.

Thanks,

Will do! I'll get some good shots for you. Your pipes are outstanding, and coated silver (ceramic coated) that really shows. Absolutely awesome looking, and I know it will run like a terror.

Thanks again,

Scott

Success. Went to a vintage bike rally yesterday and the H2 caused a commotion. Rode with friends on torque monsters, Ducattis, through the hills. They love sound, say it's not too loud. I agree. Everyone loves the pipes and I had many requests to start it. At idle it sounds so cool!

Power is decent to 5, then gets on pipe. At 7 it goes wild (Much faster than my old race bike) and flies. Not sure where it turns off, I've only got one real ride on it. These Powerjet Lectrons may make difference in top end feel vs non-powerjets. Still perfecting metering rod length for bottom end. May sharpen a bit more, but is close at 52.1mm.

Thanks for great pipes! I told several your website. I used Ultra Gray 625 degree silicone around flange of pipes as gasket- we'll see how long it lasts. Unacceptable with oil leak and no gaskets. So far silicone is fine. Bike is very fast and with decent midrange, which was put to test riding with Ducattis.

Well, coat on, Brothers! It is great looking and shows off your welds. Don't let anyone paint your pipes! My Stage One engine starts instantly, and pulls fine at any speed. At 5,000 it gets good and at 7,000 it goes insane. It doesn't seem to stop. Is that typical for your pipes? They're great, well worth the money! I also love these 36 mm power jet Lectrons and will never regret the day I laid out $1,000 for them and those Gast intake manifolds. Never again all those wasted hours tuning/ buying parts for Mikunis.

Twelve sanding cones later, the Gast intakes and ports were matched- a major change from stock shape. Anyone else running them? Maybe they make a difference. They should in torque and top end, I think.

This thing runs fantastic! Hit it and pass anything nearby.

Damn does this thing run great!

I put a 15 tooth sprocket on it, and I've always liked that better. Lectrons gettting sharper and sharper-one more top- end jet experiment, metering rods right length. Tomorrow I double check and perfect syncronization. Hauls butt now! I'm doubtful that any other classic bike can match the acceleration of a decent H2 w/ your pipes, porting and Lectrons.

Handmade Chambers = building one set at a time.

Nothing can prepare you for your first ride with a set of FatCat Chambers! You only thought your bike was fast! They will make a bone stock bike feel like a heavy stage 1 portjob. Bolt on power. Much cheaper than taking your engine apart and you couldn't get this type of quality power with a stage 1 port anyway. From idle to redline power increases are unreal!

Withind an hour I had the center stand and old pipes off and the new ones on and jetted. (just a little fat for a bike night ride) The quality is amazing. It was a long wait, but as Tom assured me, well worth it. I have a couple of days of fine tuning to do, but even with a severely fat mid throttle I can tell they are going to wake the old girl up. Next step will be porting and 34mm TMs. Many great comments and even had a younger guy at a stop light ask me where I got the them. Oh, did I mention they sound great?!!!!!!! ...Also, once again, you were absolutely right about the wait. I just about messed my drawers(front half) when I unwrapped them. The fit was perfect. I can't say enough. Thanks again. Dave jarhead

Well I receive my pipes today, I put them on tonite, all I can say is WOW, they ran just like Maddog said they would, I did not have time to put the mufflers on but the throttle response, and low end power that I picked up was unreal, well worth the money, bottom line, the bike is an animal. I will keep you guys informed on what happens when I can spend some time tuning.

Darren.
