Steeda S550 Mustang GT Sound Tube Delete Kit (2015-2021)

Quick and easy install. Don't worry about removing the nut on the firewall, just give it a firm yank! Pics attached!

nice kit,you are going to need a 10mm socket with a small flexible ratchet to take the nut off that holds the tube to firewal,if you take the plastic tube off that is located on the strut wall ,you can sneak your arm in along the motor to the back of the firewall to take nut off and put the plug in the firewall, my arm is pretty big so most people should have no problem I did it in under 15 minutes

A little pricey for what you get, but worth it when you hear the difference in the cabin. I would recommend removing your strut tower brace (if installed) and dipstick to allow a little more room for your arm. A little lube goes a long way to help insert the firewall plug.

Yes, it's a bit expensive for one piece of plastic, one piece of rubber, and a stainless steel clamp. However, everything fits perfectly and is made of high quality materials. And it's all Made in the USA, which is ALWAYS worth the extra cost in my opinion. Having a 10mm ratcheting stubby flex-head wrench will make this MUCH easier. Also my car did NOT come equipped with a cowl or strut tower brace which is also very helpful for this install. This kit is worth it because it leaves a quality OEM appearance when you're done, which is what I wanted.
