Fitment of Exhausts

[R.O.R-2.0]

If you have laws that state you have to have a cat, I recommend this one    

It is a NON cat, but looks like it and doesn't restrict flow like the ones ROR is talking about. Plus it makes me LOL

makes me LOL too...

DAS,

If the exhaust is sealed like it should be and exits from under the car then  you should have no drone. The tail pipe needs to be out from under the car though, or the exhaust noises get trapped and reverberate.

I THOUGHT I had to have a cat for emissions testing here. Turns out it wasn't actually needed per the regulations but like they're going to spell that out in writing.

DEFINITE difference in noise and peak power compared to without the cat.

Also enough of a difference in smell though that proves the cat is definitely doing something. So take that as it may be.

If the car is a turbo then I would put pipe in the span, if it is N/A I would spend for a good muffler of some kind.

I think a few pictures would be helpful here but I am going to go with the span pipe if I can get it as it does have a new muffler with it.  Whole system is only 500 miles old.  

This is the system as I got it.  Header, flange, Cat and First Exhaust pipe.  Unbuttoned and no gaskets here now.

My Idea to delete it was to get a section of pipe that fits inside the existing flanges and pinch it tight with some long threaded rod.  I don't have a welder.

So that is what I did and with a bit of hacksaw work I got the pipe the size I needed and cut the 3 foot rod into equal sections and hammered the pipe inside the first flange and it pretty much slides into the first exhaust.  Shouldn't leak.  Might need welding if it does.  Have to pay for that and take pipe off to do it.

The overall look

Odd thing is that when the guy had it on the Cabrio. He ended up T boning a 3/4 ton PU and took most of it at the axle of the truck.  So the Exhaust  came off for me to buy.  On the way home with the parts as I was nearly home and was moving up to n intersection and this car starts to cut me off making a left hand turn.  They suddenly notice people in the cross walk that are in the way so where do they have to go?  Back into their own lane out of the intersection.  But to do so they are headed right at me.   Time to get Skinny little VW.  Hard on the brakes to the right a bit but not enough to run over Peds frantically moving now.  Avoided all that and the telephone pole at the end of the intersection.  

I hope that removes the curse on this thing.  But now my brakes are in need of adjustment or bleeding.  Just not where I think they need to be.   Oh, it never ends.

Bout damn time!

And on-topic, glad to hear you didn't die and all.  Hope the header works for you; was wondering about one myself before the block cracked.

[ORCoaster]

Too much rain to get the old one off and new on.  I did get the brace that goes from the header bottom to the transmission and may have to do something with the middle hanger but overall I think this is going to work. 

For ever the optimist eh?


CRSMP5  we are waiting on them there pics of this rig of yours.  Maybe in new thread by now I just haven't looked.   

[CRSMP5]

only travel pics for now per say... im going to put the bathtub up on lift for some pics this week.. pull the scrap gasser, rip tranny apart for rev gear parts.. do some scrappin... its a odd duckling.. interesting frame set up... thinking of using as a copy, do a little wider.. add some say b3 or mk3 vr6 front stuff... aka make wider and such.. then a new aluminum box built on one.. on bags.. lower.. areo dynamic so 25mpg not seen so often at 80+mph...

On my Fiat NA I made 2 SS mufflers tube is SS 1.8 or 2 mm,nothing big deal tube in and tube out.
For 10 yr no salt can do anything,perhaps 5% more noise.

cut the flanges off the cat

scrap the cat

take the 2 cat flanges

weld pipe/resonator between flanges..

you are welcome

[ORCoaster]

Found out the the cat was about 4 inches short of the total length I needed to get the tube around the corner down by the fuel tank.  Slipped in another adapter and seems to be about right. 

I would have whacked the flanges and did what you suggested but I think this cat might be of value to someone else and if so I could recoup some of the cost of this system by selling it.  So I kept the flanges on.   Maybe I should have cut them off the pipes instead and slipped in a straight pipe.  No, the header flange/adjustment doughnut has one of the flanges on it. 

It is a pain not owning a welder for stuff like this.  Might just swing it in to a local shop and ask what they would charge to tack and weld the one pipe.  Three loose connections on it.

I'd weld that for you in trade for the cat.  i bet somebody on Craigslist would too.

too bad i wasnt closer..

i have a GUTTED cat that has those flanges on it..

technically you only need ONE flange.. the rear one..

you can cut the rear flange off the header adapter, and weld a pipe onto the adapter..

then weld the other end of the pipe to the exhaust system, or weld the flange to it and bolt it up..

[ORCoaster]

Having the gutted cat would have been tempting but it still would have left me a few inches short.  There isn't much wiggle room for a larger than stock pipe down the side of the linkage, around the corner to the  fuel tank and up over the rear brace.  Thanks for the offer.
