I have an 87 4runner and I put these on it I have recieved good performance gain and an increase in gas mileage. A little bit of a tight fit but overall is great. Only complaint is they were painted with regular paint I repainted them with high temp paint and it still peeled off I don't see the point in painting them if it's not done correctly!!

Old Stock Set
Pros: well built, definitely designed for my truck, adds power 10 - 20 %
Cons: my egr connection and the collector adaptor connections leaked, thin paper gaskets.
I work in a shop and tried to install these headers on my lunch hour, couldn't do it... Required at least another hour to finish so I could drive home. ended up with three exhaust leaks for a day. To be fair, I had to cut off 4 exhaust bolts on my convertor that were rusted and disintegrated... I changed my convertor on another day so I had to cut those bolts off. Added a lot of time. The header adapter had bent flanges which is why they didn't seal, I am sure that happened during shipping and not manufacturing. the three bolts were just too short to seal the connection so I used more washers and a tailpipe sealing putty to stop the leak.
If you have extra bolts on hand and a hammer, you will do fine with this set of headers. Ultimately, a very good set.
