This is the ultimate Dodge SRT-4 exhaust downpipe! It is 100% stainless, 304ss flanges, 3" 304ss tubing mandrel bent, stainless o2 bung, TIG welded and includes a High Flow OBD2 Compliant Catalytic Converter after the exhaust cutout. Manual block off plate is included as well as o2 housing to downpipe bolts. The pipe measures 3" all the way to the end where it reduces down a hair to accomidate the factory or aftermarket cat-back exhaust systems.

Turbo cars perform much better with less backpressure (the turbo spools faster and with less resistance). That’s the idea here. This eliminates all the backpressure created by forcing the exhaust air through the oem catalytic converter. This downpipe will bolt into stock ‘08, ‘09 SRT-4's. This downpipe has an o2 bung in it, meaning there is a hole to screw in a wideband o2 sensor. A plug is included in the event you don’t add a wideband o2 sensor. This downpipe is the best of both worlds. When closed it will be much more free flowing than stock, yet not too loud. When open it’s a whole different beast - it screams! This can be opened without lifting up the car. We have positioned it to be able to be accessible from reaching under that car and removing the 3 wing nuts. When the exhaust temperature rises you will need a pair of pliers to open/close it because it gets HOT. Manually this cutout can be opened/closed as many times as you want.

Downpipes are made in batches per order, please allow 5-10 business days wait before your custom made downpipe ships.
