New equal length headers

[GaryR]

Were any before/after dyno runs done on a stock 3.0 with the 1.625" medium length headers??

My experience is that these headers will move your power-band up about 1500 rpm over the SSI's. So if your torque sweet spot is at 3700 it will move it up to 5200 and you'll top out around 7500 or so.

I added the quiet riot sensing auto baffles and restored lost low end after installing these headers without sacrificing top end.

My experience is based purely on drivers seat experience, no dyno testing was done, and no animals were harmed.

Thanks, but I want to see dyno results as I run at 4000+ RPMs 100% of the time, but its on the track. I plan on having my car dyno'd before the 1st race at Limerock, hope to see good results!

We have another system that will be dyno tested soon and will test these headers as well to compare. The two systems are for different applications so this should tell us a lot. There is always a packaging compromise and so far the medium length headers have done what we hoped they would do; give a good option to those with engines above 3.0L that need a simple system made of long lasting materials / workmanship that works with any dual inlet muffler. We like our mufflers but understand folks need options.

Very cool Brian!
