I was lucky enough to install this Invidia Catted Downpipe and the Perrin non resonated quad tip exhaust at the dealership I work at. Total labor time for both products was about 3 hours. Great quality, great value. IMO the combination of both parts gave me exactly what I wanted in loudness and depth.

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.

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.

  • Q: Perrin catback   Dangerdan 20 days ago


    Is there anything else i would need to install this with my perrin cat back on a '13 hatch WRX? Also, what is the difference VS a bell mouth down pipe ( such as COBB) ?

    • A: This will be a direct fit with the Perrin Cat Back. The only difference is the flange in the middle of the bellmouth on divorced wastegate downpipes. It separates the exhaust port from the wastegate door to reduce turbulence.

    Any concerns with drone with this down pipe on a '14 wrx hatchback?

    • A: It is hard for us to answer questions regarding drone. Most aftermarket exhaust system will have some sort of drone but it seems that everyone has different tolerances to it.

    What is the difference between this and Cobbs 3inch downpipes? Is this going to add more power, and will it fit a 2016 sti?

    • A: The 2 downpipes will be similar and have similar power. They will add more power but tuning will be required. This will fit your 2016 STI.
