Which is better for my 03 lx coupe. The DC Sports Stainless Steel Exhaust or the MagnaFlow Performance Exhaust. Looking for the most gain and hp and the nicest sound. Deeper sound.

Did you check out YouTube videos of each setup?

Yes but as far as performance too. And you cant really get a real feel for the sound on the videos.

Performance gains from an exhaust are very subjective. For the pipes, you want something stainless steel (to avoid corrosion) and mandrel-bent (smoother bends) and not too huge (2.5 inches max). Our little engines aren't really designed to be run with really wide-open pipes since they are relatively weak and need back pressure to operate effectively. As for mufflers, the quieter they are, the more restrictive. Unfortunately, a lot of them sound like garbage.

I'm debating between the Magnaflow or just going to a muffler shop and getting a custom job. I hear it's not prohibitively expensive and plenty of people here have gotten good results.
You also might want to consider going for an EX setup, which moves your catalytic converter under the car so you can upgrade your header.

I have the Megnflow system with a Megnaflow high flow cat. and I haven't heard anyone complain about the sound, and over the 3 years I've had it probably 3 people have said it sounds nice. It won't make your car sound like an exotic or anything but it is nice sounding.

Exhaust power increase is extremely minimal on the d17 engine. You might feel it in the top of the power curve, but unless you plan on tuning your car you are basically going for the best noise maker.

I find the dc exhaust to sound slightly "ricey" vs the magnaflow. I think performance-wise they are pretty identical.

aren't those both just axle back systems i think your better off just slapping on a good sounding high quality universal muffler and calling it a day.
