Hey - I am looking for a nice low rumble for my 92 bonni. Anyone have any opinions as to what muffler sounds good (mean) as opposed to loud and obnoxious? I just put a free flow magna flow cat on it, now I need to consider the muffler. Any ideas would be great!
Thanks,
Tony

Flow master series 80 sounds good. With an exhaust it'* all personal preference.

I've used GOERLICHS | A Full Line, World Class, Exhaust & Emissions Company
They sound really good. Not too loud. Just the right amount of rumble and no drone.

I've got Magnaflows. They are bundles up a 3" exhaust, no resonator, Goerlich Hi-Flow cat and TOG'* headers. Magna Flow Mufflers and Hi-Flow Cat on Flickr - Photo Sharing!

Like Nighthawk said....exhaust is a personal preference and what may be loud for you is not loud enough for someone else.

Flowmaster series80 here.

YouTube - My friend'* 97 SSEi before tuning

That'* a 97 SSEi with a Magnaflow cat, no resonator, and a Magnaflow muffler.

Hey guys i was also looking into this. When i see mufflers that are labeled universal should i be weary? What type of specs should i look for that will fit my Bonnie?

The 92-99 Bonnevilles have a single muffler in the back that has one input on the side and either one two outputs with output per side or two outputs on one side. Those will work. A single in/single out muffler would work on a 2000+ Bonneville.

This is a stock muffler for a 94 NA Bonneville.

It sounded like that right out of the box and has only been on the car a little over a year. The car is bone stock also. 95 SSEI
