I have the same question... is the production version a single or dual HFC???

 

inpeng did you get a chance to take a vid of your car, I would love to hear it?

 

Have the Turboback installed on my car now. I had it done by a shop since I can not find my ramps with moving right now. They said the fitment was perfect. The sound of the exhaust can not be appreciated by you tube videos. Really those videos give you no idea what any of the exhaust really sound like IMO. I will say the exhaust isnt near as quiet as the video makes it sound, but its not exactly really loud either. Around town driving its much louder than stock, but on the highway I would not say its louder at all unless you drop a gear to pass someone. The sound is kinda addictive. It makes you want to get on and off the car to hear the rumble. The one thing I was not sure of when I got the car was the tips of the exhaust. My wife looked at them and said they fit the car much better than the stock. When I first got it installed the car was filthy from rain, so it was hard to tell. After a good solid cleaning I really like the tip especially when you look straight back at the car. They fill the holes perfect. As for performance I know everyone says they feel a difference after every little mod. I am not so easily pleased. I think there is only 2 things Ive done that I feel power. One being the intake, and the biggest being the exhaust. The exhaust was the most drastic difference to date. I say if you do not have an exhaust get one the car really likes to breathe. I know a tune is the best bang for the buck, but the car really likes this mod as well. If you like Perrin products you will not be dissapointed with this one. Plus their customer service is second to none.

Here's some pics. They are not very good cause it was dark and the car was super dirty. I plan on better ones in the future

Just got mine today. Gonna be a big weekend.

 

Unboxed/unwrapped and joined with the MXP downpipe and wideband before they all go in this weekend.

Cant wait to tune her afterwards too.

 

the only thing that is holding me back is the fact that i want the o2 housing combo and im not sure if its going to fit this exhaust

 

Got it installed....few complaints about the installation (bending the cat's heatshield out of the way to get the cat back to fit was a PITA!).

Sound - VERY livable. You could not tell anyone you got this and they wouldnt notice if you were just driving around normally. WHen you get on it, it opens up, but it's by no means LOUD. This is the perfect exhaust for the young professional or adult with a family who doesnt want his car to be annoying or draw too much attention, yet wants to free up some ponies and get a little bit of sound on the side.

I would recommend this exhaust for sure.

 

^I didnt have the installation issues, because I got the full exhaust. I agree though its nice. Im betting mine is a little louder since high flow cat, but I love it. The power difference is great to me.

 

Well yeah, you got the full turbo back, I went with just the catback since i have a downpipe already and im waiting on a better HFC option out there.

BTW, i looked inside the stock cat...WOW does it looks restrictive. I cant wait to get that thing out of there and replaced by something more free flowing.

 

This is a really nicely put together piece. I think you should leave the tips blasted. IMHO

 

Is this for sale already???

 

Will perrin be making an O2 housing for this as well?

 

That's good to know.
My exhaust came in Thursday and I am looking for a place to install it. Could any muffler shop do this installation?
I can't install it myself because it is very cold outside and snowing. And also I don't have the equipment to do this.

 

Of course any muffler shop could do it. I did it in my garage with a jack and some stands and a metric socket set.

Plus, 3 glasses of wine.

 

Any shop can do it. If you got turbo back warn them how difficult it is to get O2 sensor off. There is a thread here on tips to get it off.


I talked to Adam about this, and I think they feel it is not that beneficial.(Cost to make Vs Total Gain) I know other vendors feel differently, so please lets not turn this into a discussion about that.
