Your HP after exhaust mods

[monnieh]

Well, I slapped my car on the dyno yesterday. Last week I removed the 3 stock mufflers and the cats, and replaced them with Dynomax bullet mufflers and straight pipe. I went from 436 to 445, and my torque went from 490 to 485. I overlapped the graphs, and the previous stock torque was only higher at the peak. Other than that, it pretty much gained a little all the way across the graph. It makes a lot of noise to make a tad more power, but every little bit counts, and I'll take it! It sounds MEAN now!

Where did you dyno?

Speed Works. They seem to have the most correct dyno around here. I usually hit the nail on the head as far as what my cars should dyno. This one came out a little higher, but I think it's a stronger car. I had hoped to get a little more out of the exhaust than I did, but you can't always get what you want.
