I am going to buy a cat-back exhaust for my car and I am wondering how you guys feel about these to exhaust systems. Which one do you feel is better? Should I go for the cattman or greddy? The thing that is pulling me toward the Greddy is that it's $45 cheaper, but not like $45 is much of a difference.
If you can help thanks.

Performance wise I think they are equivalent. Just be aware that Greddy pipes are aluminized steel. I am also sure they sound different so it's best if you've heard both. A lot of people love their Greddy, but then a lot of people buy Greddy and uninstall because of the noise...

Greddy makes an amazing product...it's just a bit loud...if you like the sound, go with Greddy.

Just buy a warpspeed or a courtesy B-pipe and any universal muffler in a style you like for like a 100$ and you'll have a catback for a lot cheaper
