I have a Flowmaster delta flow 40 series muffler and a 3 inch stainless straight angle tip. From manifold back to mufler is all stock.Looking for some help in deepening the sound, to make it a bit louder. ITs only a v6 3.8l but what i have done so far has improved the sound alot. Any suggestions on what to do next. Without spending alot of money??

does the 86 have a transverse muffler?

Yes my 86' buick has a transverse muffler and engine.

check out the flowmaster 80 series. they sound nice with the 231. and are meant to mount in the sideways locations.


they use those and magnaflo all the time on the Bonnevilles


heres a L67, which will be different on your car, but will be similar

yeah i have a high flow cat with a replica of the 80 flowmasters it called raven exhuast its a free flow muffler. and i get mestaken for a camaro or mustang all the time.

the other option is to switch to something like a CheeryBomb Q ro a hush Thrush(if they still make those).
