tail pipe exit location

tail pipe exit location

Postby astro-nomer [OP] » June 5th 2010, 3:45pm

so...
what I thought might be a muffler issue that a limb apparently triggered yesterday proves to be
only the tailpipe broken at the muffler (it seems much older than the rest of the exhaust)
so lucky me, I have a large piece of appropriately sized exhaust pipe to chop from.
it looks like I can pull-off chopping an accurate replacement piece from it and just weld the hooks on...
but since Im kinda liking the slight added rumble, is there any issues associated with exiting before the
rear tire as opposed to after?
I know going out the back is a CO2 no-no, so I thought Id check your inputs on this location before chopping
my extra piece.
(no emissions test here, an apparently almost no restriction on volume considering the "G's rides" )

thanks!

If your van is a passenger, exiting in front of the rear tire is a big no-no. You'll pull exhaust into the passenger compartment.

Exiting out the rear isn't a no-no if the tailpipe extends just past the bumper. Plenty of vehicles come from the factory that way.

well, there are almost never any passengers back there... no seats either... and no window... and the bottom slider track is pretty much
gone and so the slider almost never gets opened.
does any of this make it less of a no-no? haha
if so, would I be helping myself out by making sure the slider seal is nice and tight?

THANKS!

I'd still keep it aft of the wheel. Even if there's nobody in the back, the air back there still mixes with the air up front.

Well I heard if your exhaust exits under your car the gases can puddle up there and if someone throws his cigarette under it it can explode. but that is probably very rare.

well as it turns out I would have had to do almost a u turn with the pipe to get the side exit happening anyhow....
and my extra, reasonably new piece of pipe is nowhere near working with just a little chopping...
so I hacked and tacked and have a replacement piece that will hopefully last untill I've got some $$$
for the real-deal.
Its not real pretty or else I would take a pic... but is good experience in the exhaust dept...
and notably better than the shot-gun bubblegum business the last hobo did on there.. haha

thanks folks for your input and keeping me alive and breathing!

What I had on mine wasn't pretty, wasn't professional, but it got the job done for almost 2 years. I had an intermediate pipe, muffler, and part of a tailpipe from an E250 stuffed in there, and the rest of the pieced together tailpipe exited out back. I took it to a shop a few months ago, they welded the intermediate to the cat (was very poorly clamped before) and fabbed a new tailpipe for $80. It's pretty quiet, and it doesn't fill the van with fumes. I'm happy.

cool.
so I ended up with it exiting at almost a perfect 45 degree angle
about an inch below and an inch beyond the very corner of the bumper.
I actually like where it is now better...
but Im guessing its not gonna last me for more than another year....
dear gods I hope it does'nt need to!!
but I hope I can get it the same way when I replace the whole shabangh.

I think that's how I'm doing mine. My muffler comes in tomorrow and I will have the pipes exit pointing down a bit and back. Just sticking past the bottom of the quarters maybe 3/4". I don't like pipes poking out under the bumpers. I have the very short van, so from the wheel well to the bumper is inches so I'm sticking them out just aft of the aft edge of the wheel well and pointing 45 degrees down and out slightly. They really won't be visible, or at least not noticeable. I did one this way a few years ago and liked it except that both pipes came out the right side.

$uperJoe- considering your build, Im the LAST guy to be giving YOU advice! haha
this was totally a redneck frankenstein hack-and-patch fix for me and since it was assembled from
5 parts there was alot of potential adjustment.
the angle of the last bend in the old pipe I was using was right, so some extentions before and after landed it in the right place.


"without pics it did'nt happen"
yeah... there are some things Im happier pretending DID NOT happen as far as showing them off. hahaha

i understand that. since your van is regular height if anyone is inclined to look under there and still have the mustard to say anything to you about how it looks just tell them to look again and casually floor the van in reverse. i bet they would not say much after that. hahaha J/K. i think i found a way to get it done today. the exhaust shops in my area want 150 bucks for 2 tail pipes. less than 10 feet total. i will try it myself first for about 30 bucks and see how it comes out

I finished this today. Life got in the way so I took longer than I expected but I got it the way I wanted it. Hope the pictures show up

I'll drive this a while then take the headers off and get them coated. They fit really well. I used 2-1/4" because my 2-1/2" die is at the airport and I didn't want to drive over there and find it. I used a Flowmaster 50 which I hope I don't regret. It's not very loud, but if it gets much louder with time it's coming off.
