header, x-pipe - dyno numbers...

I dynoed 380 rwhp and 362 rwtrq after the Kooks headers and 3" x-pipe with high flow cats. No tuning yet, waiting until after a cam install. I think those are decent numbers for what I have, see sig. Biggest surprise is that I gained 80 ft lbs of torque at 3,000 rpms! And 50 ft lbs at 3,500 and 20+ at 4,000 rpms up to redline. Really flattened out my torque curve.

That's outstanding! Did you get any pics of the headers before you installed them?

No pics of the headers, but you can go to MTI's website and they have some good pics of them.

post up the graph, 80rwtq@3k seems like a stretch.

Thanks for calling me a liar. I will have to scan my dyno graph and find a place to host my pic, but I will if it will satisfy the non-believers.

did you go from bone stock exhaust to this setup? What was your previous dyno?

I dont think he was calling you a liar. Sometimes there are spikes on dyno graphs etc etc.

There are no spikes, and yes I went from bone stock to this setup. My previous peak numbers with the air bridge and blackwing filter were 362 rwhp and 346 rwtrq. So my peak numbers were fairly normal, but I was pleasantly surprised with the area under the curve. It feels like a different car!
