Instant powah!

This is probably the best thing i have done to my car besides the AP. The stock DP is highly restrictive and this pipe with the Grimmspeed heat-shield went in easy as hell. I am currently running the DP to my stock exhaust (besides the axel back exhaust) and loving every dollar i spent. Highly recommend this to everyone.
Quality Downpipe!

Installed this a few months back on my 2012 STi which already had the Tomei cat-back. As most people already knew, the Tomei is obnoxiously loud (a tad bitter with the silencer installed). With this Cobb downpipe, the car is only slightly louder but the rumble sound is less deep. It almost sounds "raspier". I also installed Ecutek and had it custom e-tuned (stage 2). It didn't throw any codes even before I flashed my ECU. On the street, I have to keep my silencer on otherwise it is just unbearable and it draws too much attention around the city. On the track, I have the silencer off and it sounds like a beast. The car accelerates so much quicker especially in S#. Night and day difference. Not sure how that tiny cat will help in emission test (yes it still exists in my country), but I got this catted version mainly for keep the noise down. This downpipe does tapered down to stock diameter just before the flange, so you would need an adapter gasket (I have the Grimmspeed) if you plan to run a 3" catback. No leaks, easy to install, 5 stars easily.
Amazing.

Amazing quality, fit and finish. Makes a ridiculous difference in decreasing turbo spool up time. Improves torque and sound, slightly deeper burble with stock exhaust. Easy to install.
Great upgrade

Installed this with a Stage 2 OTS tune. The turbo seems to spool at least 500rpm lower and there's a lot more power when it does spool. Really linear power from spool to redline. Increased the sound level of the SPT exhaust on my car substantially. Sounds a lot meaner when heavy on the throttle but not too much louder when being gentle with the car. I also hear a lot more cool sounding afterfires and more turbo spool noise. Extremely nice quality, it's a shame I won't be able to see it better after it's installed. I knocked it down a bit on ease of install as the location of the O2 sensor bung is further rearward than the OEM downpipe and I had to remove and re-adjust the O2 sensor wiring on the transmission to get it to just barely reach.

Q: Cobb dp to invidia N1 catback racing exhaust Rico Suave 6 months ago
AnswerWill this dp run direct fitment to the invidia N1 racing catback exhaust single exit? and will I need a pro tune or can I run the OTS stage 2 on the Cobb accesport. Currently running cobb stage 1 with cobb sf intake and invidia N1 racing catback thanks.

A: An adapter will be recommended when using this downpipe with a full 3 inch catback like the N1 due to the Cobb using a donut style gasket like OEM but some choose to not use one. It will install exactly like the OEM downpipe you have now. The Cobb Stage 2+ map will work great with the Downpipe and Cobb intake.

Q: fitment Slowbaru09_GT 6 months ago
AnswerI have an 09 legacy gt will this fit directly into my stock mid-pipe or do i need the adapter
-
-
A: No adapter is needed to fit with your stock midpipe on a 09 Legacy GT. No gaskets are included so a new donut gasket, turbo to downpipe gasket and a proper tune will be all you need to install.

Q: Cat So lost 9 months ago
AnswerIf the cat goes bad on this down pipe can you change the cat or do you have to get the down pipe again?
-
-
A: If the cat were to go bad I think that Cobb would like to know about it immediately. I haven't heard of a cat going out unless it was on there for 10+ years. Please let customer service know if you do have a currently blown out cat.
