I recently installed my base arvinode system and am happy with the sound. Dave Wallace asked that I share my experience so that others who may install the system can learn. Mine was not a typical installation as my kar has been modified to have the exhaust through the rear valance (it is not a GT kar) and I like the look and wanted to keep it. I also did not want to restrict the exhaust flow so I decided to go with the non-concourse 2" high flow trumpet tips. I ordered the system through Waldron to make sure I could get a system modified for the GT style and have the rear resonator outlet have a 2" OD rather than a 1 3/4" OD (as would be for the concourse GT tips). When I took the system to my installer we noticed that the resonator outlet was reduced down to 1 3/4" and my installer was able to rework it to a 2" outlet and Joe (at Waldron) immediately offered to pay for the rework. The next issue was about which way to face the front muffler. This muffler has a small tube weled inside the muffler and the small tube is open on one end and crimped closed on the other. We did not know which way it should be mounted (open end facing the engine or facing the rear) and it seem to us to be less restrictive to the exhaust flow if it was mounted with the open end facing the rear. Turns out it should be installed the other direction with the open end facing the engine. Since there were no instructions on how to mount the muffler, Jow immediately offered to split the cost to have them turned around but due to some modifications that had to be made to the rear end of the muffler to get a good fit to the piece that goes ove the axle (the flange had to be cut off and welded directly to the over axle piece) it can not be turned around, so it will not be changed. It still sounds good and Joe says that this will not hurt the performance of the system and makes it a little more raspy sounding with a little resonance or drone possible that otherwise would not be there (I do notice a drone between 1700 & 2200 rpm's but it is not that bad). Joe also told me that he is now going to start adding a simple instruction with the system to insure the muffler is installed in the correct direction. My overall experience has been good and Waldron (Joe) has been very good to work with.
This is in no way a complaint about the system or about Waldron as I feel they truely know what customer service is all about. I only post this at Dave's suggestions so others may learn from my experience.
