Complete the header upgrade on your TRX
The supercharged HEMI is the heart of your TRX. These Kooks connection pipes finish a matching long tube header installation while joining the factory cat-back, so you can upgrade the front exhaust and keep the rear system you enjoy. Choose H.O. GREEN cats or the uncatted Competition Only arrangement.
SKUs: 35213100, 35213400
Keep the factory rear connection
Both choices use 3" pipework and 3" OEM outlets with two-bolt rear flanges. They are made from 304 stainless steel and require Kooks headers at the front.
Choose what comes with your pipes
35213100 supplies the uncatted Competition Only pipes with fitting gaskets and hardware. 35213400 supplies H.O. GREEN catted pipes. The catalyst choice is the main difference between the two configurations.
Fitting your exhaust
Keep the original rear-joint gaskets and hardware: these are reused to connect the pipes to your OEM exhaust.

Do these fit the factory manifolds?
These connections are made for Kooks headers. Order them as the front connection for that header conversion.
Can I retain my TRX cat-back?
