Mr. PLate
You're da man!
Today at AX, quite a few people commented and inquired..is it a Turbo, wat kinda exhaust..etc etc. They sounded so good at WOT.
Now all I need is power to match the sound.

Two feet of 2" 316 stainless = $28
Two mufflers welded = $60
By far the best $88 I ever spent!
Leland, I've got to hand it to you, you've made my month.

I like it but I hesitate to start it up before 8:00am so I don't wake up everyone else in the rowhouses!

Most of my neighbors are retired, and I'm trying to startle them into heart attacks every morning.

So who did the LPMM mod for you? I just started reading up on this and I'm interested in getting the mod done to mine. I think we need to get together for wobbly one soon so I can check out your rumble!
Cheers

From the burns website:
321 stainless steel tubing is one of the most desirable materials for exhaust systems because of its excellent resistance to fatigue and cracking at elevated temperatures.
It is usually the material of choice for high temperature turbo applications, unless extreme requirements indicate the use of Inconel.
We have extensive experience with 321 and will be happy to assist you in using it.
304 stainless steel tubing combines excellent physical properties with a remarkable resistance to corrosive agents found in automotive exhaust emissions.
304 tube is the most cost-effective grade of nonmagnetic stainless steel for general applications, but some professional racing teams use the higher heat-resistant properties of aircraft grade 321 stainless steel.
We have considerable experience with stainless header fabrication and will gladly advise our valued customers.
As far as gage is concerned, I would guess that the pipe on the factory muffler is either 16 or 18 gage, but not knowing for sure I would error on the conservative side and go with the 16 gage. It probably wouldn't make much difference either way, but the price difference is minimal and the weight saving would also be minimal by going to 18 gage.
