Got my cts catback installed to complete the turboback. Also had a brake fluid flush and replaced the fuel filter.
The catback is amazing. I love it. Not as loud as I was expecting, which isn't a bad thing at all. It definitely sounds a lot better than it did with just the downpipe. It's a lot deeper and has a bit of a grumble when I engine brake now. It's also a lot more sporty sounding and not so 4 cyl angry bees sounding.
I've never been 100% satisfied with my exhaust with just the downpipe. My last car had a catless downpipe with an aftermarket muffler and it was loud and droned like a son of a bitch, so I've always been a little leery towards adding a muffler on this car. Now I know I should have done it sooner lol
