Just installed the new Cobra Pipes on my Nomad. Ordered them from Cruiser Customizing. The pipes and exhaust gaskets came to $437.90 with free shipping. They even matched the price from another web site. One little hitch on the order, I ordered the Tapered Ends which of course look like stock pipes, the Packing Slip said Tapered Ends, however, They shipped me the Slash Cuts. The Slash Cuts are more popular than the tapered, the sound as per Cobra isn't that much different, and I wanted new pipes on my bike so I put them on.
Negatives on the Exhaust System:
1) The welds on the pipe are not a nice clean cut as the OE Factory Pipes.
Due to this welding design the Factory Engine Exhaust Pipe Clamps
do not have a flush fit against the cylinders.
2)The clamping set up for the heat shields could have been designed
a little better also for a much easier install.
Positives on the Exhaust System:
1) The pipes itself were fairly easy to install. The OE exhaust came off quite
easily also. The process took about 2 hours with clean up.
2) The Chrome finish was in nice shape
3) Had someone else take the bike for a ride so I could listen to the
exhaust as they took off and drove by. The bike sounded pretty good and had a nice
rumble to it.
Just a note-I wanted to see the difference in performance with each mod being installed. I wish I were able to give dyno-figures during this process. Hopefully I can when completed. No Idle or timing adjustments have been made. It has been put it on, run it, and see what you get for results. I have not yet added the recommended Fuel Injection Processor Kit (Power Commander or Cobra FI200, etc)
As for the Cobra Pipes with the stock engine set up the bike ran great till about 90mph. That's when I felt the top end performance starting to drop off. This is I believe due to the demand for more air through the intake while using the factory air filter. I had put in a K&N Filter earlier then removed it because of the lean mixture it created (See 9/12/04 K&N Filter/Wagner LazerBlueLighting). Bottom line in my opinion you’ll need to install some sort of Fuel Injection Processor Kit or New Jets for Carbed Bikes along with a High Flow Air Filter System to make your Machine run properly when installing a new exhaust (i.e.-Cobra-Vance & Hines-Jardine, etc)
When you crack that throttle open people will know your coming. The pipes are louder than I expected especially since I'm used to riding such a quiet bike. I think it will take a little time to get used to. When seated on the bike the sound at idle for no better of an explanation I think is “tinny”. I guess I was hoping for a maybe a deeper bass tone. (I know this is no stereo but we all look for the ultimate sound from our machines). When cruising on the Highway at 70mph the exhaust has a nice smooth comfortable tone.
I’ve decided to go with the Cobra FI2000 Tri-Pot Digital Fuel Processor, which was recommended by Cobra (of course) on the Pipe Installation Instructions. I shall also reinstall the K&N Air Filter at the same time. When done I’ll give you the results. Unfortunately for me as of 7:00PM in NY today the Cobra TriPots are on Back Order till November. Due to this unforseen situation I now shall go with my alternate the Dynojets Power Commander III USB. This unit has been the most popular for a Digital Fuel Processor Unit on the market. I purchased the PCIII/USB today from Direct Parts for $296.32 with free shipping. I hope to have by Friday next week.
Any comments or feedback shall always be appreciated
