My ExoticSpeed sounds amazing and the titanium blue tips look amazing. It's not annoyingly loud, but when you step on it (5Krpm+), it's like driving a race car!

FWIW I've had both the greddy se and the racing beat (currently have the racing beat). The greddy looks and sounds awesome, I actually really miss it, but I got a 3" midpipe and decided I wanted to run a full 3" exhaust, and the greddy is only a 2.5" system. It's obviously true that no exhaust is gonna give you a lot of power but if you want to go more performance oriented I would make sure you get a 3" exhaust. I love my racing beat but it's actually a bit too quiet for me, and I'm running a Agency Power resonated midpipe. The racing beat mufflers are baffled to quiet the car down. I'm currently trying to get my hands on a Greddy SP2, Exoticspeed, or maybe HKS legamax. I thought about the turboXS but I have concerns over quality.

everything is trial and error with exhaust... which i have come to learnz...

Im in the same boat as you. Ive pretty much narrowed it down to the Borla and the ExoticSpeed R1-T. Im heavily leaning towards the ExoticSpeed because I absolutely love the sound it makes. Heres a quick link to a great vid on Youtube of it.
