Symposer Delete

Hi all , whats everyones experience of the above ? good , bad no different ??

Personally like having less noise in the cabin. Makes for a better commuter car experience. When on the gas on a weekend drive, there is still plenty of noise made by the engine and exhaust anyway.

No downsides in my opinion.

If you have the stock exhaust and intake then I’d suggest keeping it. Without it the car is VERY quiet and loses a lot of character.

Have to agree; just installed a stock exhaust on a stock car with a symposer delete and was shocked at how quiet it is now.

I have the stock exhaust, but all the intake parts, along with a strong tune and the delete. I get all the noises I want from under the hood.

If you're totally stock, keep it. They've been known to fail and cause leaks, but I suspect they were driven hard to cause that.

I like what it adds to the cabin as is.

If you're not altering the performance characteristics of the engine, there's no reason to delete it. Just plug it.

However if you're new to the car, keep it for at least eight months or 8k miles of mixed driving conditions. The engine revs quick and the symPOSER helps acclimate your shift timing and rev range; helps keep you from over-revving or/and money-shifting.

Having driven a 2017 FiST with the symposer intact for over 90K miles, I would say the most annoying thing about it is the "BBUURRrr" whenever I roll into the throttle even a little bit. When having someone commuting with me, it can be almost embarrassing. Trying to accelerate enough to show off how torquey the little booger can be to a passenger, but not trying to be obvious about it is virtually impossibly without the "BBBUURrr" from the dashboard giving away that you're getting into the throttle,...just a little. Come on man!

I now drive a 2019 with Thermal R&D 3" catback and COBB air intake. Those upgades, though a lot more expensive than the free stock symposer (LOL), give much better noises, and the sound is correlated so much more with the throttle. The Thermal R&D is quiet enough in the cabin that I think the symposer actually out blasted it, so the delete was necessary to hear the exhaust. I am so much more satisfied with the real noises of the actual intake and exhaust notes and the increased aggressiveness of the audial experience perfectly corresponds to the throttle input.

If you prefer to keep everything stock, then keep the symposer for the aesthetic experience of hearing something when you drive more aggressively. However, IMO, you'd be happier with a mild exhaust note that can be heard because you've trashed the rubber flap.

On another "note" (pun intended), a decent sounding exhaust can be had for less than $250. On my 2017 I had the resonator deleted by a local muffler shop ($70). After driving for several months, it seemed to settle into a pleasing, though quiet, throatier sound (hardly noticeable inside the cabin with windows up). The resonator pulls out lower frequencies and cancels out some of the burbbles. I later added a Borla muffler in place of the stock can ($180) and it woke up the exhaust even more. It added enough volume to hear the burbbles and exhaust sounds without being too drony. At that point, I could hear more in the cabin and deleting the symposer became necessary to enjoy the subtle exhaust enhancements over the "BBBUURrr".
