Bolt-On "Bubble" Muffler // 602/604 Crate Style Modified and Stock Car 4-into-1 Headers
Bolt-On "Bubble" Muffler // 602/604 Crate Style Modified and Stock Car 4-into-1 Headers
These mufflers are designed to replace the standard bolt-on tail section/turndown on Speedwerx 4-into-1 headers for rules that require a muffler, but not a certain part number or "spec" muffler. This is not a universal muffler, they are made specifically for your particular style of Modified or Stock Car headers so they are built to order- please call to order if not purchasing with a new header set. Available in mild steel only, but they can be ceramic coated or nickel plated if purchased with a new header set.
