from the looks of his post signature...being turbo'd i'm sure it isn't as loud.

but to the OP, when i bought my ap2. The Previous owner installed a Invidia q300 system on with the stock cat. It was ok the first week, but i started picking up the drone, and was irritated. I now have a Berk 70mm HFC which is awesome and reduced the drone to about 50% less. It's also more responses. The reason i didn't want to go with the Test pipe is due to people saying it smells, and my history with N/A setup with Test pipe is just out of the question annoyingly loud. But it's up to you.

 

With the turbo it's actually very tame at lower RPM's. I'll have to film an exhaust clip sometime, the one thing I'm actually incredibly pleased with my car right now on is the sound.

Even when I was still N/A though the exhaust wasn't terrible. It was definitely, definitely louder than stock but it didn't sound like a riced Civic or rattle can exhaust. There was a noticable drone around 3500->4K RPM or something like that but it wasn't too terrible.

I'd imagine if OP was using this along with the OEM mufflers/dual tips it wouldn't be bad at all sound wise.

Edit: OP, if you get the 63mm test pipe and then feel like it's too loud you could always add in a resonator. This wouldn't impact exhaust flow much at all, or weight, and would probably help get rid of any drone that you may have. I'm not sure if it will be necessary on a mostly stock system though.

Haha, I'll get on it as soon as the rain clears up a bit

 

Ive seen some videos where the berk test pipe has a high pitched sound when they accelerate, or just rev the engine, is this for everyone? Or just bad test pipes?

 

Just buy the test pipe. I have the 63mm Berk, and it sounds good with no negative side effects. Yes it can cause the exhaust to stink, but the only time I notice it is when coming up to a stop sign.
