to any of you folks out there that might be interested.i have just been down to the blueflame factory so they could use my z to develop a cat back full stainless perfomance exhaust system.i drove it back home with the system fitted and it is absolutely top notch.it hasn't produced any flat spots at all or any glitches.the throttle response is better as are the performance levels.we were real impressed by the sound too,not too loud but really brings out the depth and tone of the 6cyl motor.
i will put a couple o pics on over the weekend so you can see it on my car.anyone thats interested have a look on blueflame's website.they are a real nice bunch of people and very eager to help. :bow:
