To complete this installation you will need to MODIFY the Original Equipment (O.E.) Mid-Pipe by expanding the outlets from to 2.25" to 2.5". This system upgrades your '84-'91 Corvette from the stock 2.25" diameter Axle-Back system to a more aggressive 2.5". The system features the classic S-Type sound with no drone inside the vehicle. It has dual BORLA® intercooled style 3.38" x 3" rectangle polished T-304 stainless steel tips on each muffler for a custom appearance. BORLA® Cat-Back™ & Axle-Back exhaust systems feature patented straight-through and multi-core technology to unleash hidden horsepower. Increased exhaust velocity adds power, driving excitement, fuel economy, and the distinctive BORLA® Sound of Power respected by motoring enthusiasts everywhere. Each system is built from premium, high-quality T-304 austenitic stainless steel, superior to T-400 series knockoffs (such as 409), to give you the absolute best in performance and durability. Ultra-smooth mandrel bends ensure maximum flow & power, and precision computer numerical control (CNC) manufacturing ensures an accurate fit. Best of all, BORLA® stands behind every system with a Million-Mile Warranty. Just what you'd expect from the world's most experienced (and most winning) exhaust brand.

Apply the Oil first prior to using your dermaplane. I used “for sensitive skin.”
Scent: For Sensitive Skin, Size: 2 Fl Oz (Pack of 1)
I only had to apply a small amount to my facial areas where I use my dermaplane. It was easy to,apply, wasn’t messy, didn’t irritate my skin or cause any reaction. It worked great with my dermaplane and soothed my skin.

Smoothes and decreases irritation , not a bump in sight!!
Scent: For Sensitive Skin, Size: 2 Fl Oz (Pack of 1)
I wish that I had found this product sooner-it’s amazing! I would always get bumps and irritation after dermaplaning-this is a complete game changer. You will not be disappointed-just make sure that if you have sensitive skin to get the right one, as there are different options.

Smells weird
Scent: For Oily Skin, Size: 2 Fl Oz (Pack of 1)
This works fine for what it does, but it definitely has a strong odor that I find very unpleasant.
