    EFI Premium Silencer

    Posted by Bob A on 30th Aug 2017

    Looks and sounds terrific! I can't comment on durability of course, but it didn't discolour or anything on the first couple of rides. No installation instructions, so my hint: On my E5 the exhaust fit over the header perfectly, so I thought, OK, easy. No. The clamp provided has a filler block intended presumably to provide a smooth round inner fit, but it wouldn't let the clamp tighten enough. The answer is to take the largest of the 3 "inner" adapter sleeves provided, expand it slightly with your fingers and slip it over the OUTSIDE of the exhaust. Then expand the clamp and slip it over the sleeve (I had to make sure the filler block was positioned over the open space in the sleeve). NOW, tighten it all up. Installation this way should take just a few minutes instead of the hour it took me to figure it out. Bottom line though, highly recommended.

    Nice Rumble with Servicable Baffle

    Posted by r.tillery on 24th Jun 2015

    This unit has a better T-type pipe clamp than the economy silencer, there's no need for pipe adapter spacers on my 2012 C5 Classic EFI 500. The rear "can" hanger mount has more adjustment. The T-bolt clamp is a little tricky to "hide" with the heat shield, but the improved clamps/hangers & proper fitting pipes make for an easy upgrade installation, the baffle system also makes for a real nice rumble but not too loud or overbearing. I expect years of good service from it. An excellent upgrade & I would certainly recommend it.

    As promised earlier, my update. I have now added 332 miles on this silencer with no problems or signs of over heating. This milage includes a 140 mile trip with average top speed indicated at 60-65 mph for about 30% of the trip. Also includes three short higher speed test runs at 75 mph indicated.

    A classic British silencer

    Posted by Richard230 on 26th May 2015

    The EFI Premium Silencer looks great, is about half the weight of the stock silencer and is very easy to install. The chrome seems flawless and there is a removal diffuser at the tailpipe that does a good job of cutting the exhaust bark so that the sound is about what you would expect from a classic British single from the 1950's or 1960's. The silencer comes with a removal chrome heat shield not shown on the product photo. The heat shield is held on to the front of the muffler pipe with two hose clamps. Fortunately, the hose clamps are not very visible when the heat shield is installed. If you are looking for a nice muffler to replace the stock bazooka, this would be a good choice for a very reasonable price.

    This pipe exceeds my expectations

    Posted by Dave on 27th Mar 2015

    I only have 38 miles on this tube so far but I am impressed. Perception and mesured response may be two different things but this silencer will get your attention. I was ready for a little low-end loss of torque but didnt feel any loss, quite the contrary. The sound is very pleasing, not the "fart" of the OEM unit and the top end acceleration seemes to be improved. I'll throw in my two-cents again after two hundred miles but in the mean time this looks
    (& sounds) like a winner!
