magnaflows suck on a 3.8, go to 3.8mustang.com, they have sound clips and pros and cons for everything. but from personal experience get a set of gt mac cat backs, high flow cats (any kind) and an h-pipe. i had an x and it still sounded good but had a ghostly wallow to it. but it did roar like hell and was throaty. only con was going to a dumb *** exhaust shop and they droned, ppartly due to the xpipe since it didnt do it before hand. trust me go with that setup and you will laugh and magnaflow and flowmasters. contact lx351 on here, i purchased my stainless steel 98 gt mac catback from him and it was a good price and that was when our dollar sucked. and make sure you get an h-pipe

 

I have Magnaflows and would recommend them. The kit for the V6 is #16605,
MagnaFlow Performance Exhaust.

 

Until your pulled over by the MTO for a spot check, the legal = Thank god i put cats on!

 

There is no reason high HP cars cant run cats.

I know on my turbo setup the cats were an issue, but not a big enough issue for what, $500 fines and possible de-plate ?

While I believe BBK makes a shitty product, you can still get a cheap catted hpipe by them on ebay for around $350 (click here)

Flowmaster for a mustang.

 

is the x-pipe no good?

 

I don't like it, but its a personal preference.
