For those of you with that are new, listen to my 4.1 warmed up. The car is a 87 deville FWD.

Sounds very similar to my 88 fitted with the 50 series Delta Flow.

Downloaded the file. It sounds HUUGE. I think I'm going to go with what you got, instead of the Spintech (too drag racerish). Thanks for posting.

with all due respect, i mean it sounds good compared to stock and all... but they get meaner... if anyone wants to see an 80 series flowmaster with 3 inch hit me up at customcaddys@yahoo.com i only have the vids from my digicam though, no sound clips

Sounds like a healthy HT4100 to me, back in my H.S. day's we took the stock mufflers off our cars and took a cutting torch to the baffles inside the mufflers and made our own sound the cheap way.

My 87' FWD Deville still has the original exhaust system and muffler and it's still in excellent condition. I think later on it would be nice to do away with the Cat and run a true dual exhaust system from the manifolds back to two California Turbo mufflers, and for tail pipes use the old 1977 Pontiac Trans Am dual chrome tip set up like the old T/As had dropping down inside the rear quarter panels.

I ran a setup like that on my 75' Grand LeMans sport coupe and it sounded real good, and seemed to help the engine breath.
