The Damond Motorsports Sound Symposer Delete kit for the Focus ST, is an all comprehensive kit, to remove the factory sound symposer system on the ST.
The factory sound symposer system, plumbs in engine noises to the cabin, that are less appealing than the actual tones of induction and exhaust the vehicle produces. Also higher boost levels can damage components of the factory system, causing boost leaks.
Our Sound Symposer Delete kit includes all you need to remove the factory sound symposer, and then some! Each black or gold anodized SSD plate comes with an 1/8" NPT plug and hose barb(for an easy access to engine vacuum/boost for monitoring or controllers), mounting bolts, 2 o-rings(in case one is lost so a replacement is readily available), and a flexible plastic plug for the firewall.
Had a minor boost issue, purchased a new SSD to go with my Catch Can and Diverter Valve. Ran to true boost and called it good. Not sure how easy install is, we had the intake manifold pulled out for said Catch Can and its two bolts into the intake itself, so maybe took 2 minutes.
The Damond Motorsports SSD plate is machined and finished very well, and I like that it is not excessively thick. Kudos for including a plug for the firewall. It blows my mind how several other companies don't include this with theirs. The reason I knocked my rating down a star is because I could not get this thing to seal with either of the included o-rings. I went out and purchased a 1 7/16" OD x 1 1/4" ID x 3/32" H o-ring and that seems to have done the job after re-installing (fits the groove in the plate perfectly).
It looks like the issue was that the lower side of the plate was not close enough to the mating surface on the intake manifold when seated with the included o-rings (see the pictures below). Hard to tell if it's something to do with my intake manifold, but I suspect the threaded brass inserts are not aligned correctly from the factory. Time will tell if the thicker o-ring will hold. It might be good to include both the standard and a thicker o-ring in future kits, just in case?
Thanks for your feedback Ryan! Your manifold does seem a little curved there where it mounts. We'll look into doing a thicker o-ring with these.
By far the best symposer delete kit! The quality is top notch and comes with everything you need including a cap for the hole through the firewall which a lot of other companies do not include. Install was very easy and provides a great vacuum source for my blow off valve
Overall very happy with my purchase. High quality piece that even came with some extra bits like O-rings. Easy install and really does a great job in cabin noise reduction.
Wonderful product no fitment issues at all. Tightly sealed. Wonderful gold finish really makes it stand out. Will be interesting and working with damond motorsport possibly talk about a sponsorship and do some more wonderful things to the race car. Please contact me damonds motorsport very interested in going far with you guys and repping the brand all over the race car. Instagram: @boossted_st email: Boosstedst@gmail.com lets talk business.

Perfect fitment. I love everything from Damond Motorsports. Will and have recommended product. Thank You again Damond
Quality product. Used for true vacuum. No more nonstop whoosh sound.
I ordered my symposer delete and exhasut hangers from damond. And recieved within 5 days living in Maine. Awesome order to home time and absolutely happy with the products. Torque solutions full exhaust hanger kit including downpipe hanger was 111.00 us dollars most places want 99.00 us dollars just for the down pipe hanger. Great company to order from cant say enough good.
Honestly get this kit over every other sound symposer delete kit out there. Not only is it high quality stuff that fits right (at a much more affordable price then everyone else) they also give u the stuff to create a true vacuum source if u decide to integrate ur bov into ur intercooler piping👍
Quick and easy/straightforward removal of symposer and install of block off plate with or without vacuum bung for your needs and fire wall block off plug. Great first mod to do. Cleans the looks of the engine bay up nicely and allows for true vacuum if/when needed. Highly recommend.
Can't go wrong with this one. Comes with everything you need.
Great symposer delete. Upgrade from the Steeds product because this product has a bung for a vacuum fitting. I utilized the fitting to run a line from the plate to my HKS BOV for a true vacuum source. 5 stars, wells deserved. Also incredibly fast shipping, arrived less than 48hours after order.
Fast shipping thank you
Quality part and delivered in a timely manner. 10/10 would recommend
Great product
This symposer delete kit is definitely made of quality materials and construction. It included everything for the install except a ziptie to keep the factory wiring tucked away after removing the control unit. Overall, it is an easy install and a great purchase for anyone with a focus st that wants to get rid of the factory symposer.
function - it works at least for awhile and cleans up the engine bay.
some design improvement recommendations:
1. make a model without the center port, it was really hard to get the center plug provided screwed in. It was really really tight i think because of the included loctite around threads and I could never get it to be flush. I was nervous about it leaking....
2. I noticed at least on mine it started to slow leak after 1000 miles. when removed the o-ring seemed to be a little crushed and I think could be a little bit thicker (in terms of OD thickness diameter of ring) i don't think it was leaking from the center port but on the side.
I try to support local made in USA companies.
Damond makes alot of cool products for our cars!
overall it does the job
Sorry if you had issues with it Tyler! The plug included uses a tapered thread, so no need to get it flush, just tight. It's also sealant on the threads, not loctite.
I'd try out the spare o-ring included if there were sealing issues. Also be sure the bolts are Tq'd to 90-120in/lbs or 7.5-10ft/lbs. Over tightening can start to pull the brass inserts in the manifold out.
Works as expected
