Retrofit Kit for Impala, LaCrosse, Equinox, and Terrain

$399.00

With these exhaust adapters you will be able to install a 2018-2022 LFX engine (sold separately) into your 2009-2011 GM car if it originally had the 3.6 LLT!! The newer LFX engine has only one exhaust output per cylinder head due to the integrated exhaust manifold, vs 3 output per cylinder head on the older LLT engines. So our patent-pending adapters are necessary to enable the swap into an older vehicle!!


Why do the swap?

Expect More horsepower! Better fuel economy! Smoother running! Not prone for issues! Less expensive engines and more abundantly found!


These adapters will fit the following vehicles while installing a replacement LFX engine:

2009 - 2011 Buick LaCrosse

2009 - 2011 Chevy Impala

2009-2011 Chevy Equinox

2009-2011 GMC Terrain



Kit includes:

1 left bank and one right bank exhaust adapter.

LFX flange gasket

OEM converter gasket ring

all necessary hardware
