New muffler for my 85 Grand Prix.

[UOFLcards]

I'm looking for a new muffler for my 85 GP. Currently I have a glasspack on her. I am looking for something with a little bit more sound but not something too overpowering as this will be a daily driver. I was thinking about the Flowmaster 50 series Delta Flow but not sure. Any suggestions?

Dual or single exhaust :?:
If you just have factory exhaust setup ... I have a very nice Flowmaster, with the hanger and tailpipe still on it, that you can have. It sounds good and has no rust or anything on it. I am willing to give it to you but you will have to pay shipping

My GP is single exhaust. I am still running factory exhaust with just a glasspack installed at the moment. I had to install new pipe that ran from the Catalytic converter but other than that it's stock.

How much would shipping be for your Flowmaster? What series is it?

What about Dynomax Super Turbo?

Looking for some nice deep but also mellow at the same time sound while still running the catalytic converter on my GP. After searching around have heard some good things about the Dynomax Thrust Turbo muffler. How would they sound be while still running the catalytic converter? Any other recommendations?

How would the Flowmaster 40 series sound with the cat. converter and single exhaust?

Probably loud haha. I had a 95 chevy pick up with a 350, ran a 3in pipe from the converter back and had a dual outlet flow 40. Thing was loud. It had a deep tone, it wasnt irritating. It sounded really good with the tone it had but you could hear it from about a 1/4 mile away. Wasnt obnoxious though.

What about Dynomax Super Turbo?

The super turbos are actually on the quiet side but flow excellent. I plan to run them when I have my exhaust done. I'm trying to keep my car somewhat incognito though and want it quiet.

I'm going to be installing single in/dual out on my 85 GP with the stock 305. What muffler should I go with? I want a nice deep sound.

My GP has a 305 with single in/single out exhaust. I'm going to be getting dual exhuast installed soon. Either single in/dual out or true duals. Need some advice on mufflers.
