For proper turbo spool & performance it is very important to keep the exhaust in the exhaust pipe. This gasket is included in all PERRIN Rotated Turbo Systems. This Gasket is designed for 3" Garret GT 4-Bolt or 2.5" Garret T31 4-bolt Turbos and should be replaced anytime the turbo is disconnected from the downpipe.

Works on 3" Garrett GT 4 Bolt or 2.5" Garrett T31 4-bolt.
