Yes and yes.

It's a CBE it's super easy.
Once you've had a chance to use the product, did it meet your expectations?
Sounds good, has one stupid bottleneck for some reason near where it bolts to the downpipe. Chopped that off, and welded in 3" pipe to fix that when the new downpipe was installed.

It was a direct bolt on fit. No need for any welding.

Yes.

I had to move the rest of the exhaust back about an inch temporarily, then slid it back in after the cat was bolted up

What made you choose this particular product?
Actually Matt at Lethal recommended it after I tried ordering Mac, but they were out of stock.
Is this your first time buying from this brand? Did you consider other brands?
This was my first time purchasing Magnaflow. In the past I always went with Bassani Cat-back systems.
Once you've had a chance to use the product, did it meet your expectations?
Extremely happy with the Magnaflow cat-back system. Not too loud at cruising, but sounds amazing once you get on it. Quality piece and great fitment. I am glad I was talked out of MAC, I've heard many negatives around fitment with their systems.
