best sounding exhaust for an 87' 305.

[bigblue09]

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

[KoolerSL2]

ive got long tubes with 3 inch pipes all the way back with an H pipe and summit brand flowmasters.

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!

  Thats what I'm talkin about. Who needs a radio?

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  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.

[VileZambonie]

Why not come up through the bedfloor so you don't have to hack up a beautiful stepside bed

[the_legend_1981]

I 'll agree with vile sounds like a hack job to me...i don't care for stacks anyway

[VileZambonie]

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.

[ssgoodman]

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.
