I have an '83 ZX n/a with the 6 into 2 header, 2.5 exhaust, DynoMax Hi-Flo Cat, and the Motorsport Turbo Exhaust System. I live in CA so I need the smog stuff. If I didn't have to wory about smog, I would have liked to put in a Nissan Motorsport 6 into 1 header. I have heard that they are the best! I ended up putting my header on myself and drove it to a muffler shop (with open header) to hang and weld the rest of it. If I had it to do over again, I would NOT by the exhaust system as a package. The DynoMax muffler that came with it sounds good, but I could have bought it for $40. The mandrel bent pipe is nice, but not worth the extra money. It would have been easier (and cheaper) to let the shop custom bend the pipe instead of working with the pre-bent stuff. As far as loudness goes, I'm sure my Hi-Flo cat cuts alot of it out. So, I couldn't tell you much about that. There was a DEFINITE power increase though.
If you are eventually planning on putting a larger throttle body on, then I would strongly recommend getting your intake manifold modified while you have it off. I picked one up at a junkyard and had it cleaned and bored to 60mm, and just swapped mine out .
My suspension consists of Eibach springs, KYB shocks/struts, Suspension Technics sway bars, and urathane bushings all around. The ride is nice...not too stiff, and it handles great. I chose the KYBs because they have a lifetime waranty (Tokico does NOT). If you can afford it, go for the Koni's. They are the best (IMO).
Hope this helps.
