Do these systems sound good? It's the cheapest cat-back I've seen, so I thought I'd ask you guys about these.

 

I have it on mine I like it personally but its not real loud either. all depends on what you are looking for it rumbles alright but then again I dont like loud annoying cars I like to sneak up on them and blow past them it does sound good from the rear of the car though

 

Is the dynomax 3' in and dual 2.5s out?

 

Dynomax is basically a mandrel bent stock replacement, they come in 2 1/2 and I *think*, but I'm not sure, that the H.O. ones are 2 3/4. Their 3 inch system is dual outlet on the drivers side, 2 on the left like the SLP, but I've never seen the dynomax one. I'm not sure if they are a tip like flowmasters or if they are tucked under like stock, I didn't get a clear answer from them. I emailed them about 3 inch exhaust and got this reply:
