Flow(Masters?)

Well I wanted to replace the cheapass
parts store mufflers currently on my
69 C10 P/U with 350/th350. They are light
guage metal and sound like it. So I bought
a set of 50 series Flowmasters. There seem
to be rather strong opinions on these mufflers
but compared to the crapola that I have on
now, they're an improvement. (They were
on sale to boot)

My question is...do I have to put a continous
bead around each joint or can I tack weld
each joint instead?

Also...do they tend to run higher temperatures
than other mufflers? Will I have to use heat shields?

Not sure about the wld question....but I have 40's on mine that are mounted pretty darn close to the bottom of the bed....they get very hot...in fact if my bed was wood...I would either have them moved or have heat shields installed. I think it will depend on where you install them.

I have them on my 74 with approximately 4 inch clearance from the wood bed. No probs. I also was concerned at first. I don't know how much clearance you will have though.

put a weld all the way around, or it will leak on you. As for spacing, a few inches should be fine. Mine is ~5" from my bed (not wood). I can feel the bed get warm when driving around, but not hot... But it does melt all of the snow out of my bed in the front half of my bed

My 40's are about 4-5" under my metal bed....no heat problems. No tailpipes either, the mufflers just end there.
