Just trying to get some feedback. I'm curious to see how far my ASM headers are going to take me. What kind of exhaust setups are you running?? Currently I'm on ASM headers, Thunder ORP, and Random Tech Cat-Back (which will be getting swapped for a Corsa in the future). I'm just wondering if I'm going to cause a bottleneck with the ASM's, or more pointedly, the ASM y-pipe that's only 2 1/2 inches. Thoughts?

 

Rich (Krause) still has AS&Ms on his car....with dual cats none the less. I believe his last dyno was well over 800rwhp with an auto. Very impressive! Even with 750-800rw (when I rode in it), it was pretty quiet considering the power level!!

I am sure if he lost the cats, he would probably see a 30-40rwhp gain at that level.

Definatly the best shorty header out there. There are quite a few supercharged cars turning higher peak hp numbers with shorty's over longtubes. However, longtubes usually provide more area under the curve.

Outstanding news. Thanks for the heads up. I can only HOPE that my setup is going to mesh as well as his. Good news about the exhaust setup though. Thanks man!
