are u happier with the resonated test pipe than the regular race pipe? as far as sound and performance wise?

@durtrid3r Performance wise, there's no difference. I've done datalogs to confirm this. WRT sound, I like the straight pipe better. The resonator really cuts down on cabin drone if it's a concern for you, but still has quite a bit of growl from the outside. Personally, I can handle the drone with this setup, so I stuck with the straight test pipe. I was using the resonator with the Corksport catback because the drone was unbearable for me.

Very nice sound.

Can you explain to me what you have done exactly?

You say it is a full turbo back but then at the bottom of your mods list you say cat-back?

Where did you order your parts from?

Thanks!

@hare The full turbo-back system consists of a downpipe, test pipe, and cat-back. Some companies combine the downpipe and test pipe. UR sells them separately.

I ordered everything directly from UR.
