Exhaust turndowns behind cab

[doomriderC10]

I just did a cam swap in my 350 and am thinking about doing something different with the exhaust. It currently has two flowmaster 40s that run all the way out the back. I was thinking about dumping it with turndowns right behind the cab. Has anyone done this? Any input is appreciated

Thata about 90% of my vehicles lol. Its louder and has some drone, I dont mind it though.

i have summit welded mufflers and they dont drone but when i had them dump under the bed they sure did. personally i hate drone, i think flowmasters dumping under the bed would just about drive me crazy

[Mrknowitall]

yep, done it several times and this is what ive found..
1:the drone gets annoying, esp on the first date.
2: angle the tips outward to avoid dirt being thrown up everywhere, still tho, its gonna kick up dust all over ur truck.
3: if u have a sliding rear window, forget about using it, the exhause gasses get sucked up between the cab and bed and right into that back window...

would i do it again knowing all this??? yes,
1:i have a gf for almost 5 years now, so if she shuts up its better for me
2: frame and underbody is all bed linned so dirt somes right off, body is currently primer so oh well.
3: no sliding rear windo.

my advise: go dual 3" dumps, mind as well, 2.xx" are just a waste if u as me, do it once do it right.....

may wanna use these???
but beware theyre loud! but for performance, AWESOME (flowmaster purple hornies 3" flange to 3" dump standard leant NON JEEP

flowmasters will drone like crazy dumped. I had to get rid of mine

[doomriderC10]

Thanks for the advice everyone. I think i might look into some glasspacks. Anything to get rid of the flowmasters

2.5" tailpipes and resonators in front really took away the drone from my flowmasters..
Especially after I fixed the lockup converter...no cab insulation yet..coming soon.

i had 40 series with dumps like right behind my cab they were turned out alil and it didnt have much drone and sounded mean lol but when it did drone it was annoying as hell lol

The previous owner of my 74 truck put turn downs right behind the cab and its pretty loud on mine. I plan on running the pipe out the back, gets annoying afterwhile. Mabye right behind the tires I think.

X-PIPE, Chevelle headers and MAGNAFLOWS!!

flowmaster super 44's, scavenger x-over pipe, all 3".....dump in front of the axle, no turn downs.....

This is how I did mine - ran a short length from the headers to Warlock Racing Mufflers, took the blocking flange off the muffler and bolted on QTEK electric cut-outs, then Summit turn downs. Since summit turn downs are bolt-on, they are adjustable as far as what angle you want them blowing out. All this happens about a foot or two before the rear axle, which is still pretty close to the cab. This way all the tone is at the flick of a switch, depending on my mood. And since it isn't directly behind the cab I can still get fresh air from the sliding rear window. The thick metal construction of the mufflers also reduces vibration in the cab.

not behind the cab but close
305 2B ,manifolds to flowmaster 40s with a crossover @ 2.25
cleared out the stock manifolds too
sounds good to me,with no radio speakers thats all I hear
i went with 2.25 so i get sound without it always haveing to hit it to the floor

but not as loud as the 350 /cherry bombs on the 4X4 tho
