Great custom Exhaust deal, Stainless setup for cheap Options

[ri914]

While gathering parts for the LS6 swap I used Amazon and eBay to get some exhaust supplies. It amazes me what 240$ was able to collect.

Amazon had a full stainless mandrel bent kit for around 150 delivered. Enough to do 3 or 4 cars. A pair of coated stainless mufflers for 42$ and an x pipe for 22.50? I swear the last time I bought a mandrel bent pipe it was probably 40$ for 1 piece?

Anyway just thought I would share this info. A lot of people need help with exhausts. This seems like a great deal. ( beware, some sell the same kit for over 500$ )

Just a side note looking at the picture. Those "mufflers" aren't going to do squat for a LS in terms of noise. You're typically looking for 5-10 times the engine displacment for an effective muffler that will flow sufficient volume and still offer opportunity for baffling and noise suppression.

Personally, those look to me like resonators that would be used to "tune" a system for tone.

I'll leave final word to Ben on back purge but in my opinion it is best practice for stainless. If you don't you'll get oxide and "sugaring" on the backside of the weld heat affected zone that will eventually compromise it. I'd bet there are exceptions but if you're going to do the work, why risk it?
