What made you choose this particular product?
Bought mandrel bends, muffler and pipe from Jegs. Can't beat their pricing. They also sell the pre-bent Flowmaster tail pipe sections, which are worth the money.
Any additional comments?
Nice quiet muffler, what I was looking for.

What made you choose this particular product?
I chose it because it was a good value in terms of sound for the money. It was also plug and play whereas other systems required a fair bit of modification on my part and I didn't want to deal with that.
Is this your first time buying from this brand? Did you consider other brands?
This is my first time buying from them and I had considered Borla, but went with fFowmaster because of its value.
Was it easy to install? Any installation tips that will help others?
I installed it myself and it wasn't all that easy. The nut is just supposed to be removed from the bolt and the new exhaust should be bolted right back on. The thing is that my bolt was stripped and it was pressed in from the factory so it had to get pushed back out and replaced with a new bolt and nut. Other than that it was plug and play.
Once you've had a chance to use the product, did it meet your expectations?
It is definitely a good value as it gives a deeper tone while making it a bit louder, but not loud enough that it gets annoying. It also doesn't drone too bad when just driving around town.
