I have a 4.6 97 GT convertible and I have removed the cats.(not illegal here in NZ).I have now just the stock axle back mufflers.It sounds like a V8 now but loud.What can I add or change to reduce the volume but keep the V8 thunder?

I'd be tempted to ditch the stock mufflers and go with a name brand performance muffler. Magnaflow, borla, flowmaster, etc. Welcome to the forum.

Yes I think I will go with Flowmaster Super 44,s.It sounds mean without the cats.Lots of crackle and pop.Not sure whats in the stock mufflers,probably glasspack old school.

Original Flowmaster 40s sound awesome with an off road H pipe. This is set up I have on my 03 currently. It sounds good and clean. Classic "Mustang" sound! Deep and throaty at idle, sounds great without being too loud at cruising speeds and scream when WOT. I have an off road X pipe with Magnapacks on my 96 and its loud all over the place I still like it but prefer the H pipe and chambers now in my older age.

No I do not. I dont believe in them, JK. On both of mine Im off road= no cats. Check engine light kicks on unless you have MIL eliminators or a tune to trick the 02s. Ill be getting a tuner over the winter for the spring.

No cats

I had the 6 cats taken out and we just remounted the O2 sensors in the straight pipe blow the manifold and
had no check engine light issue.No re tune or computer tricking required.The O2 sensors don't really seem to care if the cats are there or not.This is on a 97 GT

This is how mine is. It seems to get louder with age or maybe its me getting old? But OR X with Magnapacks makes for a nice sound!

O2s making the light come on or not on are really not an issue unless the light really annoys you. I just see it as a common thing in my car

the offroad x with magnapacks has a nice idle and cruise sound that won't kill you but when it opens up it gets noisy. if you have your windows down and pass a car at WOT it sounds amazing. I think I want either slp loudmouths or dynomax bullets though

I had LM 1s and I hated them! Had them on long enough to get the Magnapacks ordered-shipped-and welded in.

Where did you get the magnapack mufflers without the catback?
