It feels like it's been forever since I ordered the backordered HM341 pipes from David Silver. Last time I checked with them there was no news as to when they would be shipping.

Stumbled onto this 4 into 2 exhaust that Carpy is offering now.

I'd prefer to have the HM341s (or even HM300s), but it'd be really nice to get a little bling on the bike this spring. Will DSS ever have them in stock again?

Anybody tried these yet?

I guess I've got a couple of months still. This winter has sucked ass. I'm getting a little stir crazy.

I guess someone needs to be the guinea pig. I ordered the exhaust and hope to have it in the next week or two.

I was very close to ordering those but wasn't 100% convinced they would clear the triangle/passenger peg support on my 72. All the pics on the site have that triangle cut off. Very curious to see them on yours!

The original Dunstalls had good cornering clearance. I'd be interested to hear if the reproductions are the same.

These are not Dunstall reproduction pipes. The Dunstall pipes were 4 into 1 into 2. These are just 4 into 2 pipes that mimick the position of the Dunstall mufflers. There is a company that actually owns the Dunstall name. It would be funny if they went after all the stuff marketed as Dunstall that really has no connection to anything ever produced by Paul Dunstall

Thx for the info Rookster...

Regardless of the accuracy of the design; I too would be interested in how they fit on a stock frame setup with the rear peg mounts still in place. I wasn't all that thrilled with the funky upper shock mount brace deal. Some might like it but not me. I would like to see pics too!

The other Derek · « **Reply #7 on:** February 22, 2014, 09:51:49 PM »

I'm a little concerned about the passenger peg mounts too. We'll have answers soon! (And some pics)

mrbreeze · « **Reply #8 on:** February 22, 2014, 10:13:26 PM »

I'm not a fan of that design (pea shooter) but they look bad a$$ from the rear view. I also would never mount to the upper shock. It looks bad. I say keep the triangles and mount to them. I have a couple of Kerker megaphones that had the mount brackets rewelded to that area and they don't look good but better than the strap. I wish they gave you a choice.......bracket at back to mount with strap to upper shock or bracket to mount to triangle.

The other Derek · « **Reply #9 on:** February 23, 2014, 06:13:35 AM »

The strap to the shock mount will be avoided if at all possible. My thought was to mount it to the passenger peg triangle, but I guess the clearance needs to be there first. Chopping the frame isn't something I'm interested in doing.

I'll be watching this with interest. I have a basket case 71 I'm rebuilding and it didn't came with exhaust. That strap to the shock mount is hideous on an otherwise good looking bike. Gotta be a better way than that. I hope that's a stock photo and I'm not dissing somebody's bike.

Carpy's known for pushing the line, but to be fiar he does say "Dunstall Style" which is to me clearly different from Dunstall Replica or such as that.

AS to the upper shock mount, if done right (this isn't) I like it. I have a one off RB (Robert Bane) Racing pipe. Handmade as a Honda Endurance racebike replica. The mount is a flat tab bent in a dbl L at the shock mount. ITs then a piece of 1/4 inch steel rod traveling perfectly in line with the shock rod to the muffler tailpiece, where it is once again welded to a flat tab which is bolted to the tailpiece. Virtually invisible from the side, only slightly so from the front or rear.

FunJimmy · « **Reply #12 on:** February 23, 2014, 09:41:27 AM »

I like them. Nice to see another option to the over done Yosh replica pipe.
This pipe doesn't require removal to change the filter either.

Hey MC I would love to see a pic if you could dig one up sounds nice something I could do in the shop but I can't quite picture it in my mind.

What I noticed had nothing to do with the pipes. For such a nice bike (in some ways). Did you here it when he dropped it into first and when he came back and down shifted? I thought he would have done better for a sales add. I would like the stainless. First I need to talk to him about the triangle mount and if they will be polished. I don't see a issue changing the rear mount if they are made to order anyway.

It sounds a like a horrible old twin to me.

My shop time begins around 4P. I'll snap a photo. Its hanging on the wall like at Cracker barrel.

Hey Derek, any news on the new Carpy exhaust?

samfig · « **Reply #18 on:** June 09, 2014, 09:21:19 PM »

I need a picture!

The other Derek · « **Reply #19 on:** June 10, 2014, 07:37:38 PM »

The exhaust was damaged during shipping. I ended up picking a set of repro HM300s from DSS. Here's a pic of the new exhaust but not the one you were hoping for.

Works for me!

The other Derek · « **Reply #21 on:** June 11, 2014, 06:22:09 AM »

Me too.

The 4-2 from Carpy was a compromise to allow me to run chrome on both sides of the bike. When I got the chance to grab the HM300s I did not hesitate.

The 4-2 from Carpy can be mounted with the passenger triangles (at least from my quick check), but you won't be able to mount the pegs without some sort of bracket. The mufflers are slightly higher than the factory peg location.

Exactly the info I was looking for. My wife likes to go for rides so I can't really compromise the rear pegs. Also, I am very jealous of your new pipes. You bastard!

It looks pretty bad ass. Can't wait to see it.
