This "Y-Pipe" should be used with either #11376 or #11579 to convert your stock '86-'91 Corvette from a 2.25" system to a 2.5" system.

Ultra-smooth mandrel bends ensure maximum flow & power, and precision computer-controlled CNC manufacturing ensures an accurate fit. Best of all, Borla® stands behind every connection pipe with a Million-Mile Warranty. Just what you'd expect from the world's most experienced (and most winning) exhaust brand.
