I have Magnaflow...but my situation is a bit different.

In my Bonneville, I had a high flow cat, 2.5" pipe, and MagnaFlow muffler in an LN3 powered car, the L27 sounds a bit different, in fact it will sound a lot like Peters car, you may not hear it as well as you would expect, however the performance increase is there. Peter...please add your insights here.

Now, my Aurora, is also different, first off, its a dual set up...2 mufflers, and its powered by a V8...never heard anything quite like it in a Bonneville (that has a stock cat and stock res)

I've heard magnaflow on Gordy'* ride with that 3" pipe the shop used, wow that was loud. Do you know what'* on your exhaust already, from the headers back? On bonnevilles we have full mandrel bent tubing, a cat, and a single inlet muffler, with either single out, or dual out. 94 and up have a resonator.

I have, manifolds, to single pipe, to the cat, with mandrel bends to the resonator, to the muffler, for a right side rear exit. The exhaust is WAY to quiet. I dont want loud, but you should be able to hear me coming.

Anyone got any clips or vids plz?

Right click save as, works best for it. That'* my exhaust. And yes it'* stock....

Its a little louder than mine stock. Are you running no cat or res?

welcome to the club were not all bonnevilles here im a cousin to the bonneville but i am an H body buick lesabre with the L27. isnt the regle a w body? doesnt matter. welcome everybody here is very nice and very helpful.

It is actually pretty loud for a stock exhaust. It'* the N10 GM high-flow exhaust, option until 93, which is part of the rarity of my car. I plan on putting up many clips of exhausts after our November 1st meet. I'm bringing my laptop, goldwave 5, and a microphone.

Awww, man!!! Now I really want to be there!!! Grrr...
