so do engines, but the mounts welded to the unibody dont fall off. so do factory down pipes for exaust systems after the exaust manifold, 98% of the time they dont crack. Hell the vance & hines pipe on the dragbike isn't braced by anything it vibrates ALLOT, we use it as the kickstand for the bike, and it hasn't cracked for 4 seasons.

 

You've never owned a CRX pushing 225+ whp, huh?

Those are also braced. The manifold is braced to the block, and the downpipe to the back of the engine. The way the downpipe fastens to the cat is like a hinge, when there isn't a real flex-joint. It's *engineered* unlike most of the DIY stuff.

How many cylinders is it?

You are aware that dynamically balanced engines, like V8s, can run ---- material turbo manifolds with near-impunity? They don;t vibrate the poor things to pieces.

 

krb fab was local to me.. seems to have quit doing business around here... he was a good guy n all for workn outa storage garage..

sorry to see the ---- get fucked up, but easy fix

 

4 cyl 1478cc, somewhere in the neighborhood of 13:1-14:1, air cooled, huge cams, 48mm lectrons. solid mounted to the frame., but the runners also go through the flange.

 

my KRB fab downpipe ownz.

 

lol thanks rawr

Yea my dumptube crack to ----, and it was mild steel. Both have been on my car for less than a year

I think im gonna replace this manifold with an LSD miniram, then get this one repaired and sell it off. This car is my DD, so i think i'd rather not trust krb's welds anymore

 

must be the weather...

 

you really are a ***.

 

i think that prolly has alot to do with it...the dumptube cracked as winter began...now th mani cracked as its starting to get hot...altho in ohio are wether isnt all that extreme either way

 

good luck with the ----
