X pipe question

I am considering the GTPro Single X pipe (secondary cat delete) but first I would like to get some feedback from anyone that has one installed. Is the fit good? How much louder is it? Any drone? Any noticeable power gains?

Thanks in advance.

I have this Single X-pipe from GT PRo. If your planning to install it yourself without a lift, have fun! I did in my garage on jacks stands and it was a pain in the ***. Also, they claimed to me to send all the tools to cut the stock pipe and install the new x-pipe. They forgot to send the pipe cutting wrench but they did next day air one to me, it is a piece of junk though. They also sent the wrong clamps the first time, but did make it right and next day aired the correct pipes. After I got done cursing and laying on my back struggling, I finally got it on. It isnt much louder than stock. I actually seems a bit quieter idling, but a little racier sounding when you get on it. As far as power, I think it feels a little stronger, seems the RPMs raise quicker. I also have K1 Tune but had it 10 months before I added X-pipe. Fit was ok, it might actually be perfect, but laying on my back on the ground was like i said before a struggle! Would I do it again? Probably so! I am looking into upping to K2 package just not sure how loud its going to be keeping the X-pipe with K2. Anyone with any thoughts, let me know!

Appreciate your comments. Seems you had few issues initially but overall you are happy. Is it "raspy" at all? How is it on the highway - any drone? I love the stock sound but want to make it a little louder without ruining the tone.

My thought was to do this and then do a K1 after.

Here is a video posted by unbreakable1 on his car. http://www.youtube.com/watch?v=0C7KTFwv7D8

There is no rasp, no drone, I can assure you of that, I would not stand for it.

My most sincere apologies on your struggles, yes a lift makes things very quick, on your back and on the ground is a bit tough for sure, it can be done (you did it), but not fun for sure!!

Hey Brian was wondering do you by chance do install at your shop since I am local (kind of). Could you pm me a quote on price with install and how long you'll need my car for? Thanks.
