Overview

This high performance muffler has been developed for vehicles with 4" sidepipes such as 1965-74 Corvettes or vehicles equipped with Hooker Super Competition Roadster and Side Mount Headers.

High temperature packing material absorbs noise while producing a powerful mellow sound. These mufflers, as tested on a 1968 Corvette with a 427 cu inch engine increased horsepower by 40 at a peak of 5500 RPM and 20 ft.-lbs. at peak of 4500RPM versus a leading aftermarket undercar header/turbo-style muffler combination. The outer case is constructed of durable 16 gauge aluminized steel protected by electrostatically applied high-temperature black paint. The inlet/outlet is a 2.5 perforated core in a 4" casing.

Not what ad picture promotes - just patches - no more
Size: 24 x 35mm
For twice amount of money that other tire kit repair offer - it has no glue, no lighter fluid, no scratch tool - just top $ for patches. Show in video how to fix, but after you get it you'll find that you need to go back online and order, glue, lighter fluid, scratch pad, and perhaps even a roller tool. Just order a kit with needed accessories & patches to start with at half the price.

Rectangle shape covers & adheres well.
Size: 24 x 35mm
This is a rectangle shaped patch that I prefer over circular patches. Covers well and gives new life to inner tubes on the used bicycles I repair to give to charities.
