IMR Catless Primary Downpipes G80 3.3L

This is the initial release of the preorder group buy. As of March 15th, products will take 6-8 weeks to be delivered.. We expect to start shipping these by May the first or second  week in May. This preorder helps us to purchase purchase raw materials in bulk to for your uniquely designed flanges and bends. 

IMR has developed a set of downpipes to enhance the power and let the turbos breathe on your 3.3TT G80. Our primary downpipes feature a bellowed mouth, allowing proper flow from the turbo through the downpipe. We've also increased the inner diameter of the exhaust pipe from the factory 2.00" to 2.50". This will allow the air to flow faster from your engine and through the turbines in your turbo. The end result is faster spool of your OEM or aftermarket turbos. This will compliment our secondary down pipes, mid pipes and axle back which are now available.

-304L Stainless steel backported tig-welded construction

-304L Stainless flanges, allowing proper heat dissipation and protection from the elements

We now carry mini 02 sensor cats that eliminate P0420 codes. The cat attached to the sensor and doesn't impede exhaust flow. This item will need to be placed on your 02 sensor bung for the secondary downpipe.  The o2 sensor will then be installed in this o2 sensor cat. The primary downpipe should never have the o2 sensor cat in the upstream bung near the turbo. 

Go Catless for more power and faster spool!!! 

Catless down pipes require a tune to maximize performance and avoid overboost.
