$55 converters by themselves.
OR
A bolt in unit for $125 I bought the bolt in unit more then a year ago and other then needing a sawzall it was very straight forward.

Hope that helps you out!

Alright, perhaps you can answer my question about resonators.

Some people say they have them, some don't. I always thought the resonator was inside of the muffler... but I suppose not. I see you're signature says Magnaflow res and muffler. What'* up with that anywho?

I believe in 93 or 94 GM starting putting them on Bonnes. They are located after the Cat but before the muffler. They give your exhaust a smoother tone and eliminate any raspy notes from your exhaust. Some people prefer to run without them, I myself am not one of those people.

this is the one I have on my car. It is a 4 pipe with a straight through 2.5 perforated pipe surrounded by stainless steel wool basicly.

Resonator = good. I wish my '93 had one.

The cat will depend on the size of your exhaust. It'* either 2.25" or 2.5" in diameter.

I have 2.5", and I just put on a 94006, and I'm pleased with it. It'* close to the stock in size, slightly overkill by the numbers...

A shorter version would be the 91006 and many here have that too. I just wanted closer to stock length, and bigger = very slightly quieter in theory (my car was really loud, now it'* just loud).

I'll have to record a clip of mine some time... I may not have a resonator. When you stomp and let off real fast (before it hits governor... which is hard to do in park), when it revs down it does pop and sounds kind of raspy. I'll record it whenever I get my car back from trans shop and see what you guys think. I know when I went to votech for auto tech for three years, the sound I'm hearing was always a sign of little to no back pressure.

I'm not sure if I like it or not, but if does have a resonator, it'* staying on.

I'd be willing to bet you have a resonator. A little pop from the exhaust once and awhile is normal espically after letting off after a WOT blast.

The exhausts in our Bonnevilles are pretty free flowing from the factory with the bigest restriction being the manifolds on the Series 2 motors. (the series 1 motors had better flowing manifolds.)

Louder is cool... however I'm pretty much all stock other than gutted airbox. along with K&N drop in filter. Only mods I really plan on doing in the future is Cat, Exhaust, and INTENSE Fenderwell Intake Kit. Unless I can find some other cheap mods to give me some extra hp, without getting into the engine real heavy (this is a daily driver and I really don't have a substitute), I'm going to try and go quieter but aggressive. I don't want to sit at a light and have people say 'ha, that guy thinks he has a race car with that loud exhaust'... I want them to say 'hmm, that family sedan actually sounds pretty good... wish mine sounded like that'.

Now if I ever get an SSEi (broader range of mods), that may change . But for now, unfortunately, don't plan on leaving the 15 second range :( lol.

Ported lower intake, you can change your UIM & LIM gaskets while you are there. And ported exhaust manifolds. ( I have a set I've been meaning to weld up and port from my 98 )
