so what do u think is the best sounding exhaust for an 87' with a 305. i have a single to dual flowmaster right now and thats just not cutting it. any suggestions?
-
Nothing sounds better than true duals
-
Well we have factory manifolds on our 84 with no cat, comes off the y pipe into 3 inch pipe, straight into a single in 3 in flow master 40 and dual 2.5's out.
I love it.
I think the bigger diameter pipe makes a difference in sound and not having cats does too.
I ran duals for years and glasspacks, and have duals now on my monte carlo with summit knoc off flowmasters and the truck sounds a whole lot better. I got long tubes, gutted cats and 2-1/4 pipe on the car.
glasspacks sound great if you don't have anything after them, if you run tips or taipipes on them they get annoying around enclosed places they cme in and out like bah, bah, bah instead of a steady roar.
I ran that setup on a 76 c10 built 350 long tubes, no cats 2-1/4 pipe and glasspacks dumping under the bed, no turn downs it was loud and mean.
My monte carlo now has those knock offs and is alot quieter then glasspacks, I want to do real flwomasters, but a guy i knew had some knock offs and now has super 44's on his monte and he said they were almost identical sounding.
I say if you can run headers, no cat, or just put a pipe thru it and not just punch it out, so it's just straight pipe with the cats housing wrapped around it, then run duals and flowmasters, maybe dump em behind the cab, or turn em out if you want it louder. If you want quieter try out back or behind the tires.

true duals with single chamber flowmasters dumped right infront of the rear axle.I prefer an x pipe, but the true duals with this setup sounds awesome.
-
I have headers, true 2 1/4" duals with H pipe, stainless Dynomax Ultraflo's and 3" Magnaflow long tips behind the rear tires. It sounds good and doesn't have that loud drone at around 2000 rpm that Flow's can have. I had a Dakota R/T with a dual outlet, single in Flow 50 with dual 2.5" pipes and Megs tips exiting shotgun style under the roll pan, and a 3" pipe with gutted cat from the factory y-pipe to the Flow. It was very loud for what it was but popped and sounded nasty on decel. I like the way my truck now sounds. And it got noticeably louder after doing the new cam and heads. Straight-through mufflers though can give more of a "rappy" sound. Chambered mufflers give more of a "gargly" hollow sound. I want to try Hooker AeroChambers when I redo my exhaust. Never heard a pair of them before. And the bigger the dia. the pipe, the louder it gets.

I like it loud ;D
-
ive got long tubes with 3 inch pipes all the way back with an H pipe and summit brand flowmasters.
ill have to get a vid clip of it.
its deep and loud.

I have this setup with headers. It sounds so good that it'll stand the hair up on the back of yer neck! ;D
-
;D Thats what I'm talkin about. Who needs a radio? ;D

I have an 87 Stepside LWB w/ the 350 TBI. Im working on my exhaust as we speak... just ran through emissions on the stock... so bye bye. Im running headers to 3" collectors... then stainless exhaust tubing to dual stacks ;D Im relocating the gas caps (dual tanks) to the tops of the fenders and cutting off the steps, with a slight mod to the bed rails so the stacks sit real nice and pretty like. Once I get it done I'll post some pics and maybe an audio wav as I wake the neighbors... it's gonna be glorious.
-
Why not come up through the bedfloor so you don't have to hack up a beautiful stepside bed
-
I 'll agree with vile sounds like a hack job to me...i don't care for stacks anyway
-
They can look alright if it's done nicely...there's a pic on one of the threads with stacks I believe. I don't feel like searching though.
-
2 headers, 2 long pipes and 2 exhaust tips, nothing else but that. no cats, no mufflers.
-
I'm gonna do something a little different on my choptop. I'm gonna raise the step about 4 inches, then graft the lower section from a fleetside to it below the step and match up the body lines to the cab a little better.Then exit my exhaust through that area. I think the one reason alot of people don't like the stepsides is because ( to me) the bed doesn't match up to the cab very well. It looks incomplete. The 50's trucks had the running boards that tiesd everything together, and the 90's had the lower half of the bed match, but the step was two high. I think I can make it look right, just gonna take alot of blending in the lines.
-
Guys, I'm not hacking anything, just removing the steps. Im going to try to do it without touching the top rails if at all possible, but I think that they might have to be modded slightly. I appreciate the responses. Im not a fan of the through the floor approach... all the fleetsides do it that way, and since I have a light bar too there's just no way! My buddy, who owns a machine shop, was a little hesitant when I mentioned stacks, he did it before to through his stepside bed, 79 I believe, and over time from them getting hot w/o mufflers the bed actually got burned around them! At any rate I'll keep you all posted on the progress!

not a fan of that...

I personally wouldn't run the stacks but whatever you like

that should sound good
-
I like the sound of single exhaust run through a turbo muffler. Not to hijack the thread, but while we're at it, I have a single exhaust system run through a dynomax sport turbo muffler and love the sound, but want it louder. Any suggestions? I'm about rady to try a cherry bomb. 78 c20 no cats.

I thought of this for my 79 stepside, but after looking at the cost of stacks, I'll pass. I was going to go through the steps as well as running them inside the bed brings the stacks too close together, in my opinion.
My 5 y/o watches the Cherry Bomb commercial on Trucks and wants a set (it's his pickup after all). I was going to get the traditional glass packs, but I don't want them that loud. Anyone ever run Cherry Bomb's new turbo style? How do they sound compared to Flowmasters? I like the way the Flowmasters sounded on my 72 chevelle (350 sbc with 2" duals)
-
To me, the exhaust has to fit the truck. On my 1981 4x4 I have long tubes running down to 2.5" pipe out the back to some 4"x18" tips, no cats and no mufflers. It sounds pretty good when I run through that 4 speed! On my 1983 4x2 I have long tubes running into 2.25" pipes feeding into glasspacks and on out the back to some 3.5"x24" tips. It has a good rumble but nothing outrageous. Actually right now it gets annoying with a collector leaking on the driver side.
Nothing compares to the sound of true duals!
-
I have the Edelbrock SDT's on my 01 Silverado and they sound real good. Not an overpowering rumble at idle, but sounds nice and clean (this is through cats) and true duals as well. Now, when you stab it, it sounds wicked and it has ZERO drone at highway speeds. Plus they have the ti-tech coating and after a year, they still look new!
-
I have 2 1/4" parts store special 28" glasspacks on my truck, its fairly mellow...quieter than original 40 flows..they're turned out at the rear corners of the bed, similar to Vile's truck, except mine have slash cut chrome tips.. The length of the glasspack is what will affect longetivity and sound..my truck had these on it when i bought it in august of '06, and I've not been able to blow out the packing, even when I was trying really hard..
-
sorry for the delay.
here how my 85 sounds.
consists of my 355, Flowtech Long Tubes, 3" pipes, 2 1/4" H Pipe, Summit Branded Flows, and 3" pipes out the back at the bed corners.

its a bit poppy and i am in process of making a cross member that i can run the pipes almost straight without hanging too low and with a X-Pipe.
