Adding two mufflers will reduce your HP/TQ. It's going to restrict the exhaust even more.

Yes but if its another single chamber one it won't be enough to make a diffrence and you need a little back pressure.

I'm S/Ced and have aftermarket headers I'm also planning to get the P-tuning S-pipe. Any tips or feedback will be greatly appreciated. Thanks.

P.S. I'm currently still researching this(using the search button and all lol) so no flamers this is a feedback and addition information post.

If you are running our exhaust system on a SC tC, we highly recommend you run your factory header. This is the best combination for sound quaility, and it will reduce the dB level quite a bit. It has been tested on some local SC tC with our exhaust system. Also, the HP gain or loss between an aftermarket header and stock header with our exhasut is insignificant.

Back Pressure + Turbo = lack of power. You don't need back pressure in that form. I admit that first I was a little skeptical of a 3 inch exhaust, and thought I would never buy one until I hit the 400whp range. But after seeing the gains had by it, less back pressure increases the HP enough that I will go 3 inches way before 400whp.

That is why I said a little, N/A would require a little more.

Lose the headers. You won't have a giant rice can hanging off your car, it will lower the sound significantly, you won't have to cut up the PTuning exhaust and you won't even notice the difference in power, like MrC stated.

Ok thanks for the feedback guys, I have decided to go another route, I'm going back to the 2.5 piping and picking up the greddy se exhaust. Once again thanks for the feedback you guys gave great info.
