Stainless Exhaust fitted.

Post by ian » Tue May 26, 2020 7:51 am

Fitted stainless down pipes and mid section to complement my Sportax rear and link pipe.
The left hand pipe would not line up :shock: and had to be realigned in my Jawhorse to fit :lol: Found a mixture of studs holding the front pipes on including some beautifully made turned stainless items at 57mm long, the plain part was too long though so a few washers were needed, the thread was too tight to chase with a die, but the fit on a new brass nut was superb. The spacers beneath the flanges could not be fitted as the flanges would not then pull up to the copper seals, also the flange has an angle on it which will never sit correctly on the spacer. Got a bit sweaty fitting the left pipe and had to reach for another beer (instead of the box of matches) as an engineer with 40+ years exprience this was a tough job. ian :o

If it's the spacers I think you mean they fit on the outside of the flanges.

Update, headers leaking doing a gpmg impression :shock: upon investigation both flanges are bottoming out on the cylinder head casting :?: stainless headers are within 1mm of the originals (length of the larger diameter) flanges dont seen very distorted :?: but the head casting bears witness marks from the flanges, I can sort this with a 4" angle grinder and the dremel, has anybody experianced this before :roll: many thanks in advance, ian.

Front pipes from Force, but yes new copper washers fitted, the flanges look to be cast but the only way that I can see is Mr Grinder. :shock:

Are the flanges on the header Pipe’s the right way around?

They would fit better flat side in, but the bevelled side is inboard giving a flat surface for the brass nut to contact with (this is how they came out) :roll: ian.

This is not a problem I have read about or come across myself. Is it possible to post a picture showing the exact problem? Pictures worth a 1000 words etc.
