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.

Very nice
Size: Large, Color: Blue White Petal
Perfect length and fit and doesn't cling if you like a more relaxed look. I purchased 3 of these for work and I love them. I can wear them with khaki cropped pants and sandals, very cute. After washing and line drying there hasn't been any shrinkage and the fabric stays nice. Perfect for warmer weather climates!

Sizing seems to be different depending on color!
Size: Large, Color: Mini Leopard
Ordered in Mini Leopard in Large and Pink in Medium. The Mini leopard was too big and the Pink was to small! Decided to return both and order the pink in large. That fits!!! Sizing is different in different colors! Like the style and hopefully it will wash okay. Kept the pink, large! It did come extremely creased!

Sizes not consistent
Size: Medium, Color: Mini Leopard
Hit or miss with these. I got 3 all the same size. One is perfect, ones a little tight and one I can't even wear bc the sleeves are so tight. Hang to dry or you'll have super wrinkles.
