Bonneville America Forums Forums Technical Forums Exhaust Chevy605 pipes

Won a pair of custom long cannons from Chevy605 on eBay earlier this week, got home today and they were at my door. Popped them on with a little hi-temp RTV and took them for a test...they sound great! Nice deep throaty rumble, good growl when you get on the throttle, but not so loud that I'm going to make the neighbors hate me (okay maybe when I leave for my unit PT at 5 in the morning...but otherwise...)

Highly recommended.

Don't need pics, they're just gutted TOR's. I also got a set of gutted long TOR's from the same guy off of ebay. I love the sound and they seem to be working with my set up, I'm putting out 68rwhp so they can't be hurting my power output.

I bought those too, he does a good job on them. Those are how I learned what was inside the pipes to start doing my own. I had to remove the last baffle they still weren't loud enough for me.

I almost forgot the pipes I bought are the cannon type. He takes the tapered pipes and cuts the end off just past where it starts to taper and then guts them leaveing the last baffle with 3 holes drilled in it. I say again he does a very good job but now I do my own. If you don't have the tools or skills they are well worth it. He says no need to rejet but I would.

I got a pair of "Chevy605's" just in case I get cited for my D&D's here and Denver and they make me go back to "stock pipes." Slipped them on and rode around one day, wasn't real thrilled, but then 1) I'm used to D&D's, and 2)there's still a lot more that could be taken out of the pipes. And, like Ian, I think they'll be a good start when I want to start figurin' out for myself how to get baffles out/ drill them etc.

I also just bought a set of Chevy605's and haven't received them yet. I have a new 07 TBA and don't like the look of the tapered pipes. The ones I bought from Chevy605 are the long, slash-cut ones from a speedmaster and I think they are much nicer looking.

I was thinking about keeping the stock pipes, but I don't really have a use for them and like I said, I don't like their look, so I'll take him up on the $75 core charge and return them to him.

In terms of "loudness", how would you rate them (scale of 1-10 or in relation to other pipes)? And I am not looking for a lecture on people's perception of loudness.

Many thanks,

I have heard the ones on SSGRex's bike. On a scale of 1-5, I would say 3. You can hear them, but still hear the cam chain. Overall, they have a good full sound to them.

Correct me if I am wrong.

When you purchase a set, are they a lower price if you send your current pipes to him and higher price if you don't?

Are your own pipes then modified and sent back to you, or are you sent someone elses modified pipes?

Thanks again,
Ceuls

Well it works one of two ways...
First, you paypal him what you won it for, plus $75 which you get back when he gets your old pipes in the mail - he even sends you a prepaid UPS label to stick on the box his pipes came in to send yours. That's what I did.
The other way is that you send him your pipes first, he works on them, and sends them back - I'm thinking that he still sends you a prepaid label but I'm not sure.
The pipes I got are long cannons (still with the Triumph engraved label), first two baffles removed and third one opened, sounds way better than stock but not ******-off-the-neighbors loud. No more Jetsons flying car sound, and I can even set off car alarms in the parking garage.

I expected he'd ship mine on Monday, since I bought amd paid for them on Saturday, but he didn't ship them till today, so I won't get them until Monday.

I am sooo tired of my motorcycle sounding liek a sewing machine. I ****** Triumph for making the machine so quiet!

Dont hate Triumph. Hate the government for making triumph make the stock pipes so quiet.

Soren

Which government makes Triumph do this; The UK or US gubmint?

Nevermind; I'll just hate them both...

That would be the EPA. Federal law says the pipes must not emit above 80 db at 3712 rpm. Modifications are also prohibited by federal law.

Just got my Chevy605's in and installed them right away. They sound awesome! Deep rumbling without being too loud. In fact, I can't imagine running pipes any louder. They are perfect.

I was planning on recording the sound and posting it online, but the dmahn sound clip is exactly what mine sound like.

Also, Chevy605's workmanship is above reproach. The pipes look brand new. Not a scratch on them and they were very well packed.

Looking through from the header end I immediately saw that the catalytic converters had been removed. Some people have said that you can see through them, but that hints at them being straight pipes. Instead, when you first look through them you can see light, but you have to tip them at angles to see through to the other end. They appear to have two offset baffles in them with holes drilled around one of them.

Whatever, they are perfect for me. They satisfy the letter of new Denver ordinace (if not the spirit) as they are factory pipes with the EPA approval stamped into the chrome, but their sound is very good. Gives the bike a whole new attitude.

I met a guy recently who was running sceptre pipes on an '05 speedy and setting the scale of his sceptre pipes at ten in loudness, I'd say these were a six or seven, and the stockers would be at about two. I would imagine that some of the fishtails and straight pipes I have heard would be around fourteen or fifteen.

Chevy605 is running another auction on the "cannon" type pipes, which are the factory BA tapered pipes with about six inches cut off of the end just behind where the taper starts, and the rest of the pipes modified like the ones I just got.

For the price and workmanship - not to mention the fact that the pipes are "factory" and stamped with the EPA approval - they are the best pipes for the money in my not so humble opinion.

By the way, I applied new sealant to the pipes and made sure the clamps were properly aligned, and I have no popping on deceleration or any other adverse effects. They smoke a bit, but he sent a letter explaining that the smoke is from the machining oil he uses while cutting. it should burn off in no time.

Stamp. or no stamp, those pipes are altered, hence illegal
by federal law. I run Bubs, no stamp, no care. Not loud
unless you really get on it. Still quieter than 80%HD's.

Yesterday afternoon I had my bike in the driveway and it was idling with the choke on, so running kinda fast.

I saw my neighbor across the street come out of his house and he was getting into his truck. I walked over and asked him if he thought my pipes were too loud and he said, "no, they sound great!"



The back end of the pipes were pointing at him at he time, and he was across the street.

Although, since he is an Air Force Pilot, maybe he has a warped sense of loud.

For you pic hungry surfers, here are some pics of my new Chevy605 Pipes on my '07 TBA
