Default What do you have?

Can you explain what you have and why you chose to go with that set-up

I went with a 3" catback because I will be doing some custom ported and polished heads, L36 cam and some other stuff that I wont mention yet. And most likely a L36 nitrous kit will be developed on my car in the future. But I will ecentually be making a bolt-on catback exhaust for Bonneville'* and Grand Prix'*. But these are future projects, working on other ones right now.

You had an 86 MC SS ?? Sweet... I use to have a rare ( at least that'* what I was told ) 87 Monte Carlo SS Aeroback.

Like TY said, it seems you already know what you're doing. I am running stock on mine for the moment, but will be upgrading my car as soon as spring kicks in. I was originally planning on going with Magnaflow due to the straight flow design, but have heard that Bonnies sounds too Riced with it. I can't remember the brand name of the other one I was going for ( not Flowmaster ), but is also a straight though design muffler. Sorry.. brain not functioning... its the weekend . I am also contemplating on removing the resonator. I've been hearing different stories on it. Some people say to remove it, but a resonator as far as I know is basically also a straight through design style muffler, and doesn't create a lot of back pressure. If I loose too much back pressure, then my Torque would suffer. I would definitely remove it from a V8, but don't think it makes a difference with a V6... then again, mine is also SC'd. Any input on it ??

I think the muffler you're thinking of is the Walker Turbomax. I've run two of 'em in the past, and they're a straight through design, or at least used to be. I haven't changed my muffler yet, but I did have to replace my cat. It'* an Autosound Hi-flow, and I noticed while it was being installed, that I don't have a Resonator, nor was there originally. Until my Cat, my exhaust was virgin from the factory. Drifter, what year is your Bonnie? Maybe they started using a resonator with the Series II?

Mine is a 97 SSEI, with the series II.. I do believe they started adding resonators in 96 models and up ?????

I got a '95 SC and I got a resonator as well. I had it on the lift at a muffler shop not to long ago (blown cat 'n' stuff) and it was there plain as day.

Default .

They exhaust on bonneville'* are not made for performance they are made to be quiet at any expense even performance. They say it won't mateer what you do with the exhaust . But i recomend either Edelbrock or flowmaster. Dynomax is also good but edelbrock is my fav . Dynomax might just be a match made in heaven cause it'* not too loud but will release back pressure.
