The Invidia Catted Downpipe features a Divorced Wastegate and cat, this will seperate the exhaust gas exiting the downpipe, creating a smoother exhaust flow, thus resulting in more HP and Torque. All this while keeping the exhaust fumes clean and safe for the enviroment.

The downpipe is constucted of 304 stainless steel 3" mandrel bent tubing and bolts up to any stock replacement catback or stock unit. New Downpipe Gasket recommended for purchase with this downpipe.

I installed the Invidia DP two weeks ago and wish I bought this sooner. The difference in power is black and white. Just one tip when in stalling, make sure the wires from the o2 sensor clear the driveshaft . I learned the hard way haha and it set off my check engine light after a week.

Awesome dp, crappy shipping

The dp is awesome. Solid construction, great welds. But when it showed up at my house, the box was destroyed and the bolts kit and gaskets were gone. I called my friends at RSD and they helped me out tho. A+ customer service

Great downpipe!

Invidia doesnt really need much of a review their products speak for themselves. I paired this with the Invidia Q300 and it did make the exhaust note slightly louder...more throaty i think. My main reason for writing this review is that I can CONFIRM fitment of this downpipe with an EWG. I had worries that the EWG wouldn't fit properly due to the placement of the cat, but everything fit fine! It's a super tight fit for sure, but nothing is touching or rubbing anywhere!

All I can say is WOW, what a huge difference in power this downpipe makes. I have a Cobb SF Intake, Cobb AP3, Invidia N1 Dual Catback and now the Invidia Catted Downpipe. I HIGHLY recommend you get a Protune when you go Stage 2. My tuner did a dyno run on Cobb's OTS stage 2 tune, my car made 245hp/255lbft. After his adjustments for a conservative tune, it's putting out 297hp/300lbft at 18.5psi max boost! The car pulls significantly stronger and the downpipe and N1 dual combo sounds MEAN.

Stage 2+ Great results

I bought this down pipe when RSD had a 10% off invidia deal. I performed the install myself in my garage with the car on jack stands. The car is a 2011 and had 35k miles on it. With a bunch of pre soaking with WD40 and some patience the install was done in about 5 hours. It requires the removal of the intercooler which you will get used to if you work on your sti yourself. The downpipe was BEAUTIFUL out of the box. The wields were flawless and the finish on the pipe itself was very nice minus a few scratches. The flange sat perfectly flat against the turbine and has no leaks. It has been a year since and the down pipe is now burnt/brown in color but this is expected as i had gotten allot of WD 40 on it during the install. Still no warping/leaks or rust. Great product.

    What are the supporting parts required to install the DP to all stock system?

  • AnswerQ: Emissions  Rusty Shackleford 1 month ago

    Is this Carb legal, or emissions legal? If so, where will I be able to find the paper work on this downpipe so I do not get any hassle from the county.

    • A: All items sold are for Off-Road use only. Any state or federal emission and safety questions need to be checked with your local DOT/ EPA for compatibility with current emission standards in your area.

  • AnswerQ: fitment  ET15 1 month ago

    would this downpipe bolt right on to a nameless catback exhaust?

    • A: We do not offer the nameless performance catback exhaust so we would not be able to confirm this but as long as it does not taper down to 2.5 inch at the end of the pipe this will directly bolt up to it.

    • A: Nameless catback has a flange. You will need to get the 3 inch donut gasket from Nameless in order for you to avoid leaks. Would also run a grimspeed gasket there too.

  • AnswerQ: dp to stock parts  bajo15pl 2 months ago

    do i need any adapters or gaskets to install the downpipe to my stock exhaust ? will there be any problems bc of no aftermarket cattback?

    • A: You will need the 3" to OEM catback adapter GRM 077044, the OEM donut gasket SUB 44022AA123, as well as the turbo to downpipe gasket GRM 028001. You will also need a tune or Accessport map as well.
