Cheap easy HP gains?

JAAY, thanks for the link to that guys build. A very honest and thorough appraisal of his findings without all the hype, bravado, and confirmation bias so often found on other websites like suxspeed. He clearly "gets it".

My oem exhaust manifolds had a minimum of 1/4" extra weld thickness at the entrance & exit pipes pre & post warmup cat. Grinding this away to minimum weld thickness minimizes the flow restriction while maintaining emmisions compliance. This should enhance high rpm power & possibly low rpm torque. Replacing the oem exhaust manifold gasket with a quality, thick header gasket MAYBE will reduce engine temp, although this is the one area of the engine you want hot since hot air moves faster than cold.

Have you used their test pipes? Were not talking about a complex piece here, pretty much an 90 degree L pipe with a few minor angles.

Shadrach74,

Here's the answer to all of your header/cat exhaust woes . A set of custom fabricated headers and precats from M&M Exhaust in Germany. They feature longer, equal length primaries with 2.25 diameter piping, along with an F1 style merge collector and HJS 200 cell trimetal cats - beautifully made from T316 stainless steel . Net hp increase - probably somewhere in the range of 8 to 10 hp at the wheel . Cost - approximately $3800 . Aggregate cost- about $300 or so per hp .

I'm starting to think you just have a Woodrow Wilson for Chinese goods, my pipes were equal length, metal was T304 stainless, merge collectors were the same, pre cats? Not a problem for the 2.5 people. The only thing I see is a higher price.

Look at them again . They probably seemed like they were longer, equal length primaries with a real merge collector. And, worse they were probably less than 1 5/8 in diameter .

I can't look at them, they ain't mine anymore, whatever Johnny, they improved the performance dramatically.

No, I have Fabspeeds. I assume Topspeed was refering to 6speedonline in his post, thats the go to place for bling mods!

Absolutely accurate prodriver. I go there when I need a good laugh.

My freudian slip is showing! I meant to say Topless.
