Default Invidia DP & Exhaust Install | Video, Sound & Pics

Hey guys,
Today I installed the Invidia Catted Downpipe and Q300 Exhaust on my 2011 WRX 5 door hatch. The install was super easy and the fitment was the best I have ever seen. I was able to put together a short 2 minute video that has the sound clips from the interior and exterior as well as some install pictures.

Check out my build thread here to see all of my latest installs, write-ups and videos.


Overall I feel the exhaust is a lot louder than expected but still such an amazing sound. I'm running an EFI Logics Pro Tune on 91 octane.

Enjoy the video and feel free to ask any questions or comments below!

Skip to 1:13 for the good stuff....


Some install pics too:

Stock heat shield & downpipe


Heat shield removed - ready to struggle to get the five 14mm bolts off!


Stock down pipe showing the O2 sensor and coupling with donut joint.


After view of removed downpipe.


Installed new downpipe and Grimmspeed gasket.

Thanks for checking it out!
The setup cost around $1300 and with the AccessPort it was $1835.00

Rally Sport Direct sent me a 10% off coupon about a week ago and I jumped on the deal. Also the Accessport is 10% off for about another week too.

I think retail is a little over $2000 for the same setup.

Cheers!!

I feel like I need to get this off my chest...

This exhaust and DP is F***ing LOUD! No way close to stock with a deeper tone.

I just took it for a 30 mile drive and the drone at 5th gear going 60mph is quite annoying and at 1500 rpm you might as well wear ear plugs.

I'm getting too old I want my youth back where I just didn't care...

You'll get used to it. I went through the same thing with my Invidia N1 race turbo back... And here I am now with a header and up-pipe to boot. It's always a shock at first.

I felt the same way at first when I put the q300 on my 11 hatch. You will get used to it and it will just sound normal to you after a while. It doesn't bother me anymore.

Man that makes me feel a lot better, I hope so.... Thanks!!
It just has that tone that resonates in the car and it's almost deafening.
I did find that if I crack the window a little that it releases the pressure and it's much better inside. Going to be tough to do during a Maine winter though.

Very nice note on that exhaust.. my only issue is the weight
the footage looks like a corporate, product-pitch, presentation!

so honestly you did not feel a difference in power increase after going from stock to stage 2? was it worth the money if you were going to simply stay stage 2 without adding anymore power mods?

Hmmmm, Good question... was it worth it?
I feel as a complete combo, yes. I think the Intake, Exhaust, Downpipe and AccessPORT are a great solid mod to the car. I just happen to be getting married this year and before I join my bank account with my wife I splurged and spent $2300 on mods for my brand new car. It probably will never happen again and I'm really glad I did it.

It's been about two weeks since the install and I have to say that I'm really starting to feel the difference and getting used to the new drone of the exhaust. I was able to run the 93 Stage 2+ while I was in NY for the week and WOW what a difference!!

If you can swing the package, I would do it. I think if I did it piece by piece I would have never noticed the difference.

Cheers!!

Its not a stock exhaust therefore it will not sound stock.

Wow, generally seems like you are not happy with the $ spent?! Kind of deters me, lol.

Well, not entirely.....

How hard were your bolts to get off? What did you use?

Even though I had less then 2000 miles on the car the 5 bolts on the downpipe were a nightmare without on impact gun.
I used a 14mm socket with either 2", 4", or 6" extensions and a 20" Breaker bar. Definitely take off the intercooler and move the main wire harness and bracket on the passenger shock tower. Once you move them, you will have a lot more room to maneuver.

Good Luck!!

P.S. Yes, it's still very loud inside the car. Don't expect to take grandma to the grocery store anymore, hahaha!

Sounds like hatchback people running this exhaust experience drone. My sedan has very little. If you really want to wake your ride up, get a phatbotti e-tune. Night and day difference over Cobb Stg2.

You have the new v2 Q300 hatchback exhaust, it's far louder than the v1 variant. Most people considered the v1 to be reasonably quiet for an aftermarket catback. Did you get any instructions for the IAG tail light overlays? I've been wanting to do them but can't find any writeups.

Wow, I didn't know the two versions were any different in sound... I think it's still growing on me but for a daily driver it's a little much for the morning commute. It still sounds sick though !!

As far as the tail light overlays, there really is no easy way to explain them... There is a whole lot of heating and stretching. I was able to cover the lights on my first shot without ruining the material but it's a process of stretching and thinking you have it perfect then having to peel it off and doing it over and over and over until it's really perfect.
If you try it and get hung up, contact me and I will do my best to help you out.

Cheers!

Nice pics and vid. car sounds good and dont worry you'll get used to the sound. When i installed my Greddy Tic catback in the summer it seemed too loud at first in my police infested city. but now it seems very quiet. im still using the stock dp

I wonder what the difference would be with and without the stock down Pipe? I was hoping that someone would have done the exhaust first and then the downpipe and confirm the difference. I know it's something to get used to but I have about 2000 miles on it and it's still killer loud at 65 MPH.

well im not sure if this will help much but the guy i bought my greddy catback from switched to a invidia q300 catback because he wanted the car to quiet down. he had the stock downpipe and it had a good mellow rumble to it while cruising and was much louder at WOT. this was on a 07 sti though

I'm going to be installing the same dp on the same cat back Thursday. Have you run into any boost creep since installation?

I have the catless to my q300 (sedan) I do not have boost creep. A lot of other people do get boost creep with catless (even high flow cats too). You may or may not get it.

I was just out this morning trying to get a good feel for how the boost levels were reacting to where my target is...
I still haven't done that hard of driving since I got the exhaust so it was hard to give an honest answer.
Finding a private road to open it up was a lot harder to do then expected and the closest highway is close to an hour away. So this mornings commute was all I had.
I was getting a small amount of boost creep in 1st gear (spiked to 19psi) for a split second then stayed perfectly solid through 2nd, 3rd, and 4th at 17.9 psi. I don't know enough about boost creep to know if the small spike is a real problem but I'm okay with it.

Hope that helps a bit!
