I Bought a used Toomey for my blaster got it for $100, with the header flange, no springs, no silencer.
I must start by saying wow!!
When I first opened the box, I thought that doesn't look any different, don't see how it could do much.
First I pulled of the DG pipe and layed it beside the Toomey the differences were quite noticable the Toomey was more open in many places, it had a look of purpose. Next to the Toomey the DG looked a little wimpy, kinda like it was thrown together.
The toomey head flange was a much better piece. The flange I removed was flat on the motor side relying solely on the pressure of the bolts and slight compression of the exhaust gasket to seal in the exhaust gases. On the pipe side it relies on one spring and a 1.5 inch long piece of pipe that fits loosely between two layers of pipe on the expansion chamber
The toomey flange has a lip that fit's tightly inside of the exhaust gasket, and relies primarily on this to create a good seal, the bolts mostly hold the flange In place, as well as compressing the exhaust gasket which furthers tightens the exhaust gas seal. Once I cleaned the carbon off the isnide of the exhaust gasket, I was able to snugly fit it over the lip on the flange, it lined up nicely with the outside of the exhaust port and sealed no problem. The only adjustment I had to make, involved slightly widening spacing of the holes on the flange to allow it to fit over the studs on my engine.
On the pipe side it has a similar fit to other pipes the extension out for the flange is shorter and it uses two springs as most quality systems do.
The pipe itself was nicely welded and chromed the mountING and spring tabs were good and solid, the fit was a little tight, and the rubber mount on the frame had to be adjusted, it is quite obvious that they used every mm possible when designing this pipe. Since i got this piece used and it didn't include the silencer ,I repacked the DG silencer and surprisingly they fit together well, I won't even need the rubber exhaust clamp I ordered.
First ride.
Since both pipes call for similar jetting and I knew I was safely on the rich side, I went for a little test ride, and wow it feels like it might be a little falter below 3k rpm, but from there up its got more across the board, out pulls the dg through the mid and has a noticable hit when it "comes on the pipe". From there on out to well past were the dg fell off the Toomey goes balistic.
The only complaint I have is that now my little uphill trail behind my house is too small to tune any thing but the pilot and air screw , may be the needle a little.
It used to be I had to short shift every gear to keep in the power with the dg, on one particular hill I would be just past the happy spot in 3rd looking for fourth, now second pulls faster and harder, putting me In happily in third and making alot more power for the steep spot, makes me wish I had some new tires to hold it down.
I love the nice ring it has at lower revs, the big meaty mid-range and the now noticable top end hit that pulls to the moon compared to what I had. Hard to believe one little piece of hollow pipe can make such a difference, I can't wait to get out where I can tune it in. I know I am blubber rich around half on up. Should be fun .
