Direct replacement, 100% stainless, 304ss flanges, 3" 304ss tubing mandrel bent, stainless o2 bung, TIG welded.  O2 housing to downpipe bolts included. 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 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 pipe will be much more free flowing than stock, yet not too loud.

This pipe eliminates the Primary catalytic converter on the Caliber SRT4 exhaust.

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