IMR has developed a set of downpipes to enhance the power and let the turbos breathe on your 3.3TT Stinger or G70. 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 backpurged 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.

Go Catless for more power and faster spool!!! 

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