What made you choose this particular product?
Not being a prick to the environment :)
Any additional comments?
Unless you're turbocharged and throwing more than 400HP, going catless is pointless and you're just stupid and should be arrested on the spot :)

What made you choose this particular product?
I was looking for a replacement to my muffler because one entire side was basically gone. Based on what i saw on youtube , this sounded mich better than the flowmaster
Is this your first time buying from this brand? Did you consider other brands?
Yes, i considered flowmaster and HKS . But i settled on this one'
Was it easy to install? Any installation tips that will help others?
I did it myself but , i would recommend having a grinder and tightening down the clamp HARD
Once you've had a chance to use the product, did it meet your expectations?
Yes, my car finally didn't sound like a Honda and there wasn't an annoying drone on the highway anymore. I can actually hear my girlfriend in the car when she talks . ( she's a quiet person )
Any additional comments?
This muffler is a "straight pipe" muffler if that makes any sense

They cut and shortened one of the exhaust tips to match the curve or the rear bumper. Looks very nice.

What made you choose this particular product?
Love magnaflow exhaust on older chevys and muscle cars and figured it would be a reputable choice for my custom exhaust vision.
Is this your first time buying from this brand? Did you consider other brands?
It is the first time buying but had my heart set on it after trying various other cheaper brands and hearing all different kinds of mufflers.
Was it easy to install? Any installation tips that will help others?
Had it installed at an exhaust shop.
Once you've had a chance to use the product, did it meet your expectations?
It got rid of the droning and makes it sound Pretty good especially when the turbo wakes up and whistles!
