exhaust on a slammed c-10

[weekendracer728]

what are you guys doing for a exhaust on a truck that lays frame?? Do just run it out before the axle?? search button does not work for me???

Make sure you're using the 'grey default' screen that you can choose on your user control panel for the best functionality w/searches.

Many guys opt for 3/4 length car headers (Camaro/Chevelle) or manifolds to keep the exhaust above the lower frame rail lip. How far back it's ran is very subjective. Some guys (esp younger ones) love the loud/dumped exhaust so it's much easier for them. Others that want a less harsh, full length system can either snake the pipes all the way back or route them outside the frame rails. The amount of patience you have (or the size of your checkbook) are a big factor in determining which is best.

I agree witht he short headers or even stock rams heads maifolds then run along side the tranny and over the trans X memeber what to do next is still puzzlng to me but it seems some guys have cut a hole in the frame welded in a piece of pipe then got it outside the frame rail before the trailing arms....I have long tubes and mine goes under the X memeber so I drag my exhaust when I dump with cupped LCA and a 2 " c nocth

Thanks for the help. That is all done the road. I am doing rust repair now on the cab and want it back together before the snow flys so I can drive it a little...

I'm running sanderson shorty headers with my pipes up between the frame rails and dumped before the rear axle.

[dznucks]

I am curious as to what has been done also. any body got any pics?

[The Big Green]

I ran mine from manifolds and they are turned down just shy of the back of the cab. It's loud, but the 8 valves are by the back of the cab, so I couldn't get it back any farther.

I ran shorties inside the rails thru the crossmember and dump in front of the diff. Nothing hangs below the frame rails.

Hey nasty do you think with the shorties you could get outside the frame rail before it flattens out under the cab ( behind the front suspention)??? my thoughts started out thinking side pipes and trying to get it out as close the bottom of the front fender as I could to get rid of all the snaking around then I was thinking why not tuck it under the cab between the frame and rocker and dumping out the side of the bed?? I have a few Ideas for that too...just looking for a newer Idea thats all

ok just looking at my truck maybe a set of sprint car headers or roadster since I have no inner wheel wells it would be easy...hmmmmmmmm what ever happen to the old wheel well headers that you see on some gassers???hmmmmm

[Hottrucks]

heres a link to what I was thinking??

http://www.bigblockdart.com/techpages/Hustler.shtml

I think the collectors would need to be raised?? I would leave the flange and cut a hole in th side of the header to add a full exhaust ....but who wouldn't want a set of Dumps!!!!

1/2 the guys on this site.

The 'side pipe' idea can work 'cause we've done a similar stealth system (we did my buddies old 65 that way). The exhaust was a set of 2.5" Ram Horns w/2.5" pipe that immediately 90 degreed to outside the framerails. He put his mufflers on the outside of the frame under the cab & routed the tips of the pipe out in front of the rear tires. Painted the pipe w/black VHT high temp engine paint to keep it less obvious.

there is no way you could get them outside the frame rail with out cutting a huge hole through the frame. My collectors are at the top of the frame rail and that is with my motor being raised a little because of my dropmember.

Here's mine... all stainless, and all the way to the back.

smashingchuck, I really like your square exhaust tips exiting there. Mine go close to that spot, just to either side of the plate box. Mine are tucked up out of sight and turn down at the roll pan, stealth.

A Watt's Link would be hard to get around. My notch and exhaust pic is probably not going to help but here it is. My challege will be routing the exhaust around the corvette IRS, when I get to it.

Honesty I don't see the need for a h pipe. I was happy enough just to get everything to jive as it is, plus it would be pretty tricky with the amount of driveshaft travel. I've got 2.5" pipe, but if you wanted it I don't see why 3" wouldn't clear just fine.

You could sneak one side under the tail shaft of the trans so they both go over the axle on the same side (obviously the side that has the link bar low on the axle). With the IRS, I've seen people go directly under the pig with a 1-piece rectangular pipe.

I plan to weld in a piece on the bottom side of the rear bumper so the tips are "framed", then send it out to get re chromed.

I'll have an genIII engine in mine and the long tube headers I'm using are pretty much within the frame rails. I have an X-pipe in mine, so I couldn't get it through the trailing arm crossmember, so it runs underneath.

If I didn't have the X-pipe it would go through the trailing arm crossmember pretty easily. I'm not that low, so I wasn't too concerned about it. The exhaust dumps before the rear axle.

[smashingchuck]

Fenderwell headers? Seriously?

I think they would cause more problems than they would solve.

[smashingchuck]

I might as well be the first one to tell you to post some pics.

If that's toward me, unfortunately I can't. This was back in the mid 90's & the truck met an early demise after an a-arm had an abrupt meeting w/a manhole cover that was exposed about 1.5" from the road surface. No.1 reason why I don't like dropped a-arms (he wouldn't listen to me & swap to discs & dropped spindles).

kool
but this half of the site thinks

DUMPS ARE KOOL

lol

[72gmcshorty]

hey bigblock68, do you have a pic from underneath showing the exhaust?

[shortbed70]

Well mines not laying frame. I run camaro LT'sand my exhaust isnt done but heres my plan..
Flex joint off headers into x-pipe,then through the trailing arm x-member then turn through frame then turn back into mufflers then out the back following the frame. I also have nothing hanging below the frame so that way I dont have to worry about scrapping the ground.

[jasonroman]

ok. so i have an 85 longbed. when i picked truck up i needed exhaust done.
took it to a guy who messed truck up pretty good. long story. anyhow eventually he got it finished. put on new piping from manifolds back. cat, muffler, and 2 exit pipes.
now last week i took truck to a guy to do the spindles for me. and when he started flip kit and shackles, he decided it necessary to cut off piping on passenger side. right at muffler.
so now i have a muffler with two exit holes, 1 length of pipe running on the driver side that exits behind rear wheel. and an open hole at muffler.
thought about asking another muffler man to maybe cut the existing pipe and put 2 turndowns at end of muffler. ?? bad thought? that the dumping your talking about?? will it be stupid loud???
am i eating gas by having open hole now?

dont have cash to redo exhaust right now.

thanks for any opinions

I run mine from stock manifolds below the clutch linkage, above the tranny x member straight back to the trailing arm x member. There are two holes with pipe lining them in for support. From there it goes into two glasspacks angled up and then a u turn above the frame rail and under the bed to dump right in front of the rear tire. It doesn't drone like under cab dumps and is very livable. There's about 2 inches of clearance between the pipe and the bed floor.

It was really fun to make... 8 hours on my back welding the mandrel pipe around everything. but it works and sounds great, far enough back to be better than dumps and is entirely above the frame.

(note: not at full lay-out)
