I've heard for a long time that people put headers and performance exhaust on their 3.0 toyotas to get a slight increase in power. Got it back from the shop (lce headers, flowmaster muffler) and its incredibly slower than before. I guess it lost a lot of low end torque but what should i do about this? Anything to help?
Don't tell me anything about 'you shouldn't have expected it to be fast' - i know that, I wasn't. But its so much slower than before. Next move? Ive heard about regearing..?

The only true remedy I can think of is dropping in the 3.4 5vze. I don't think any money spent on trying to improve the 3vze would be very rewarding. Sounding more powerful and having more power are two, very different, things.

I think something is wrong. Your performance shouldn't be worse.

Is the check engine light on?

Did the distributor get moved for some reason?

I would check the ignition timing.

No check engine light, and I'm not sure about the distributor. I'm going to call the shop as soon as theyre open next week. But i agree, it seems like something is a bit wrong. Seems like it shouldnt have become slower, only picks up at the hp peak around 4k
