Downpipe questions and comparisons

Just to clarify, I saw that article too and I believe it was a 5whp max gain, and that's also after the second cat was already deleted and dyno'd with the cbe. Also, look at the power curve, not just max hp. Most people pick up gobs of power in the mid range. That's the 20-30hp people are talking about, not necessarily max

Yup...area under the curve, not just peak WHP

Agreed. Area under the curve or a "fattened" curve (same thing) for hp and especially for torque is what usually wins races, rather than a big but peaky max hp gain.

But I have no experience with the CS DP. All I can say is that going to a full 3 inch DP/RP (the one in my sig), with both cats eliminated, mated to the stock 2.8 inch stock system behind the RP dropped my 60-100 mph times a whole second. That is huge And that was with the stock intake. I have just installed a good CAI and will retest soon to see how they work together. If you can run catless, this is a much more power generating mod than any aftermarket cat back. IMHO.
