Default Removing factory Muffler

I was browsing around youtube and i found a video of a guy with a turbo pt that simply cut his muffler off. It sounded pretty good. Now couple of questions.

1. With this being turbo will I get any issues with back pressure
2. Can any other problems arrise from this.

Here is the video I found on youtube, I also have a short intake on mine dont know if it would make a difference.

Straight pipes are excellent for a turbo. The Neon SRT-4 comes factory without any muffler.

In many places doing so is not allowed due to noise pollution.

You could just drill a few small holes in your muffler, it'll give you nearly the same effect.

Won't be even close. A flow through resonator will tone it down a bit. The Neon SRT-4 does come with an 18" resonator. It will still be a bit loud, but the turbo will love it with faster spool times. You have to know where and when to increase the noise level, though. As ProDigit says it will also depend on how much the police pay attention to your exhaust noise, too.

Well got it hacked off, its actually not that bad. It is a lil louder but nothing as bad as the video, I think his mic was real sensitive. Its got a good deep rumble and its even nicer when i threw my shortie intake on it. And I think I can feel a lil better power difference. It might just be me though.

Not really,
It may (or may not) be that the engine loses a few HP, but apart from that you probably will just have a more noisy car.

The N/A (Non-turbo) engine needs back pressure to run right. It will be much louder too.
