What exhaust systems are you guys running and are you running a 4" down pipe as well? I would like to run a single 4" exhaust system with downpipe and cat delete with muffler but not sure what brand is the best.

Also what are the advantages of 409 stainless Vs 304 stainless?

409 type Stainless Steel is specially designed for automotive exhaust
systems.
409 type Stainless Steel resists atmospheric and automotive exhaust gas
corrosion.
409 type Stainless Steel developes a light surface discoloring which will
retard progressive corrosion.
409 type Stainless Steel contains 10.5%...11.75% Chromium
Why 304(14G) type Stainless Steel tips, flanges, internals and brakets?
304 type Stainless Steel contains 18%...20% Chromium and 8%...10.5% Nickel.
304 type Stainless Steel has excellent heat, oxidation and corrosion
resistance.
304 type Stainless Steel Looks great and will shine for ever!
How to clean Stainless Steel .
409 type Stainless Steel can be cleaned with non metallic pot scrub pads
and soap, ammonia, liquid or powder detergent.
304 type Stainless Steel can be cleaned with non metallic non abrasive
cleaning pads or brushes with soap or liquid detergent, use "Chrome polish"
if necessary.
