Wow, after doing a 3 hour trip today with the SOLO hi-flow cat, SOLO headers and SOLO NA Single I am just shocked. This has to be the cleanest, smoothest 4-banger exhaust I've ever owned! (of course it's the ONLY I4 I've ever owned LOL)
absolutely no 'rice-rasp,' and absolutely no drone. Unbelievable for such a high-flowing setup! made 157hp 185ft lbs torque to the wheels courtesy of HP tuners too! More power to be nabbed, but it was getting late. The tables need a little more fuel and I should be able to break into the 160's for hp and hopefully close to 190 for Torque! I can FINALLY pull harder on the interstate and lane-change much easier.
trying to DYNO tune with an auto tranny is NOT fun, ran the sh*t out of her! Ran her in 4th, but pretty much ran the longest single runs I've ever had to on a Dyno

otherwise that sensitive motherf%&*ing TCM downshifts on you!!! ARGH!
I promise to take pix of my rear-valence-delete, I think it looks very 'raw' and very cool. My best friend custom fabbed and mounted an additional white LED bar for the reverse-light that was removed, and then he fabbed aluminum bars to brace the outer 'mouth' of the rear bumper that surrounds the muffler. (if you don't your rear-bumper will flap in the wind!)
The custom diffuser/skid plate is still being fabbed for underneath the muffler for a 'finished' look, but I love it how it is right now. shaved a couple more pounds off the rear too!
Which brings me to my ONLY gripe about the SOLO catback: it's sure does not feel 30lbs lighter as Steve suggested...

in all likelihood, it felt heavier due to the added resonator, BUT that resonator is also the reason the whole setup sounds so BAD%SS!!!!!! (the high flow cat is definitely a lighter unit though

SOLO definitely did not let me down in terms of fit, finish and sound-quality. Seriously, the whole setup was so insanely easy to install without a single problem! that is REALLY hard to find these days! They can consider me a customer for life.
So glad I didn't go with Magnaflow...
SOLO

oh, Steve and Jeff, please feel free to chime in if I'm wrong about the weight, I USUALLY put EVERYTHING on the scale and weigh it as I've been working on this car, so please feel free to correct me if I'm wrong about the weight disparity of the exhausts! I know FOR CERTAIN the SOLO 'Race-exhuast' is lighter because there is no muffler! and perhaps that's what you meant.
