GrimmSpeed Downpipe to Catback 3in Double Thickness Gasket – Universal

GrimmSpeed Downpipe to Cat-Back 3-Inch Double Thickness Gasket, Universal

The GrimmSpeed Downpipe to Cat-Back 3-Inch Double Thickness Gasket is the correct replacement seal for the 3-inch downpipe to cat-back (double thickness for larger gaps) on 3-inch 2-bolt flange applications. Replace any time this connection is opened during service, reusing a previously compressed gasket risks leaks after reassembly. This double-thickness version is for applications where standard gasket material is insufficient to fill the flange gap.

DETAILS

• Application: seals 3-inch downpipe to cat-back (double thickness for larger gaps)
• High-temperature construction appropriate for application
• Replace any time the sealed connection is opened
• Engine: 3-inch 2-bolt flange
• Fitment: Universal 3-inch downpipe to cat-back
• Double thickness, for larger-than-standard flange gaps

Exhaust and intake gaskets experience significant thermal cycling, vibration, and fluid exposure. Each time a gasketed connection is opened, the gasket should be replaced, a previously compressed gasket does not return to its original thickness and may not seal correctly when retorqued. GrimmSpeed’s gaskets use materials appropriate for the thermal and chemical environment of the specific connection.

This is the correct specification for this connection on the 3-inch 2-bolt flange engine.
