New exhaust system on my 84 olds delta88

[Sniper]

so, I just bought this car off a friend of mine, needs a new exhaust system, the intake manifold looks bad, the carb definitly needs rebuilt.

so im tackling jobs one at a time, for this week, I wanna get the new exhaust system done, the engine on this car in question is a Olds 307, it wasnt the stock block, I cant remember what he said it was pulled out of, and the tranny thats bonded with it is a THM400, which, this combo will definitly have some power to it, so I want it to sound real good, right?

I want that deep olds sound, anyone know of a good system I Should throw on it? I was thinking flowmasters, maybe 3" pipe, what do you think I should go with?

I wouldn't go 3".. That's loud, even for my standards. I'd go 2.5" true duals all the way back from the exhaust manifolds. Flowmaster makes some nice mufflers that are real mellow in the lower RPM range but get plenty loud when you step on it. Just check out their website. Borla and Dynomax make some nice mufflers too but nothing that I've owned so I can't comment. And I wouldn't expect too much out of a 307 Olds. If anything save up and swap in a 350 Rocket engine or at least look into it. I think it'd be cheaper to make the same power in the long run.

3" sounds too hollow IMO. Go 2.5". Flowmaster, Magnaflow, Cherrybomb. All good choices, but I've never used a Flowmaster or Magnaflow, so I can't comment on them.

theres a rocket 455 there that im probably gonna buy off him, I know it would do nice in the car, but I dont want to start a project like that on this car till next summer ^^;

my goal currently is to make her street legal ^^

well, she wont be very legal once I get all them HDC3 15s in it ;3

(me defacing a muscle car with subwoofers? Nothing you havent seen before, bigger engine gives me more power for more alts)

so, say... 2.5" pipes with Super 44s true dual w/h pipe?

Yeah that sounds like a good combo. And there's nothing wrong with subs in a musclecar... I'm putting one or two or four in mine. It just has to be tasteful IMO.I hate musclecars that have rattling trunks

I have the reg 40 series in my 4.6 94 Grand Marq, 2.5" pipes, true dual in turndowns under the center...I like how it sounds (NICE rumble kinda similar to a truck), but it could be a bit louder with that same rumble IMO. I don't know how much more power your motor has, or how much more of a performance motor yours is than mine, but i've heard that the Super 44s are actually quieter than standard 40, and I've also heard that they're much louder. I'd do more research, maybe just contact Flowmaster directly.

unless you are definitely going to a bigger motor stick with dual 2.25" piping... you want good exhaust velocity and too big of a pipe will hurt that...

as far as the mufflers go its a personal choice...... unless you modify the crossmember you cannot run true duals in that car (flattening pipe on drivers side works)

not trying to be a douch but an 84 delta 88 boat is no muscle car lol, but you don't wanna go with anything over 2.5 or you will lose power, 3" exhaust is for big motors with performance upgrades.

ive made plenty of people look and feel quite retarded when they made the same assumption as you......
