Does Flowmaster make a complete exhaust system for a 1991 Nissan Maxima?
I think your car is 17 years old and most custom exhaust are for much newer cars.
Even if they do, Flowmaster and Maxima just don't sound right in the same sentence. They are more truck, hot rod and muscle car exhausts. You should consider a company that specializes in Import Car exhausts. It'll probably sound better. You don't want your car sounding like a truck.
If you really want a flowmaster exhaust, first off flowmaster mufflers come in different chamber models for flow and sound, choose how loud you want it, two or three chamber mufflers and buy or order a 2 inch in and 2 inch out or a 2 1/2 in and a 2 1/2out you may need a reducer pipe to fit to your current exhaust, take your flowmaster muffler to a muffler shop and have them replace and weld in the flowmaster muffler after all its the muffler not the pipe you need and you will have flowmaster sound, if your looking for a full exhaust for a decent price try Pacesetter Hedders they do mail orders and i would go Hedders with full Exhaust that would be alot better than a flowmaster system also try Stillen motorsports they made parts for Maxima's from Exhaust to Body kits also try the Maxima forums and or NICO (nissan Infinti car org) or if moneys no object Borla has a Stainless Steel Exhaust, and if you really want pertomance buy a turbo kit for your car, seen turbo'd 1991's on the Maxima sites, very nice cars, im in the NICO club Hope this info helps you out.
