PERRIN EVO X Turbo back build...
Well, how much power you making? 
Seriously we used this same basic muffler setup on another car making 450WHP and it made the same HP at the same boost level as a similar car with a straight through muffler. Even though the air makes a turn its all very open and free. This was on an STI with a GT3076R turbokit. I just comes down to how restrictive the internals are. And the muffler you see is like 2 straight through mufflers, but instead of connected with a y, its connected with a big chamber.
We can supply some back pressure numbers, not a problem, but not sure how this is going to help when no one else has these numbers to supply. Give us a little while and we can do that.

LOL what I'm making now? Stock....but eventually that's the plan. I always prefer to buy one part instead of the same part many times so it can keep up with what I want to archive. I want to get to 400whp and eventually maybe 500....but that's so far in the future, but I like knowing what I got can handle that for when the time come. So that's awesome and thanks for response.

Well 400 is my initial goal. But of course I won't be able to keep it at that and I want to keep going higher. So I want a system that will give better gains and free flowing as much. So thanks for the awesome help and responses.
? Some Ti tips on the exhausts out in the market look like stainless steel colored blue like Ti...looks cheezy to me. If it is done right, I think it'll look pretty good.Your exhaust has a good tone to it...you are probably going to end up in my top 3 exhaust choices

Jeff has great products. I have a Perrin High Flow Cat on my 3" DP & CBE for my ix, and I love it. I tried the oem cat first, then got the Perrin HFC...and it made a huge difference . I recommend getting the Perrin exhaust. Good American made products.
My only question for you Jeff is if you have a LICP for the stealth FMIC for the ix? If so, can you PM me the price?
Thanks,
Chris

Also hats off to Jeff!
Seriously nice write up and I love the system. I drove the car extensively on the local race track last week and what a difference. The combination of the Turbo-Back, new ECU programming, etc. and WOW!
Lovin it!
Also, on any questions that anyone has on this or any other PERRIN products (and even some non-PERRIN if you think I could answer it)
Thanks guys and gals!

Thanks for the compliment and for asking. PLEASE excuse my ignorance, but what is a LICP? If I have one I would love to help you with it! Thanks again!

I'm not a big fan of giant round tips, but that's pretty much all that's offered by any company at this point. I think you're right about the stock ovals, as they do always seem to look crooked. Not to bring up a competitor, but I think Cobb's quad-tip prototype catback looks great (and not over-large given the bumper cutouts), but we probably won't see that part for another year given their typical time to market.
If someone had a decent non-round or quad available, I'd probably be among the first in line.

A couple of questions if you have some time. I am kind of concern about the hanger for the midpipe. I posted a pic down below of the hanger I am talking about. Will the final production have a better mounting point? It just seems to be twisting the hanger pretty good. Also wouldn't it be easier to just mount the O2 bung on the other side instead of bolting the bracket on the high flow cat? The exhaust looks top notch and I am looking forward to seeing the final production.
Thanks
