2009 GXP MT
I was referred to Solo by the previous owner of my GXP who purchased a Solo system through the Camaro forum. (group buy)
Solo had my car for 2 weeks as their test mule in order to get the exhaust note and fitment perfect for the GXP application. I also drove in NightWings but it was still under development at the time. I have had my car back for a week now and think they hit a home run here.
My personal feedback after 1 week of driving.
Exhaust tips - 10/10 - Look VERY similar to stock GXP tips and look appropriate for the car. Stick out EXACTLY the right amount from the body.
Alignment of tips - 11/10 - Fit spacing to the bumper is perfectly equal in all directions. Less than a 64th off... Better than stock.
Sound @ WOT - 10/10 - Sound inside car is incredible. No comparison to stock exhaust. Sound clips coming this weekend.
Sound at part throttle - 10/10 - I have absolute control on the sound level of the exhaust. Doesn't get too noticable if driven normally. Sound get progressively louder as pedal is depressed further. I think this is why it is called a loud pedal.
Sound on decel - Noticable backfiring and gurgling on decel inside the car. Simply awesome sounds here. I have let my Satellite radio subscription expire as I have a new source of music. GOINGSOLO2, correct me if I'm wrong, but I beleive 2 of 4 cats get deleted on GXP.
Sound @ Idle - 9/10 - Idle wont wake up the neighbours (like my last car) and sounds ALMOST normal inside the car, from outside sounds moderately tuned. I beleive my idle is set too high (a whole new thread) Seems to be at least 800RPM maybe 900RPM which likely explains the higher than anticipated noise level at idle.
Power - NOTICABLE improvement throughout the powerband. DYNO results to be posted shortly. Approx 10 RWHP/RWTQ across the board, less on low end, more in mid-range. (~12 Flywheel HP/TQ @ peak) In the opinion of the Dyno shop to where I will soon be returning for a full dyno tune...these are EXCELLENT gains for an exhaust only upgrade. (IMHO - The guy at the Dyno shop's opinion should matter more than any manufacturer's HP improvement claim)
Drone - Good to go. Nothing to complain about.
Price - What can I say? Smoking deal. Incredible value? Need I go on? Sounds great, looks great, runs great, price is great, BUY ONE!
Any other ???'s let me know.
