Some people say that 2.5" will take some low end torque away, but quite honestly I've I actually seen only good things. I mean I can easily go 35 MPH in 5th and have enough power to speed up

The link that was posted to ebay should be sufficient enough. SSAC header is not allowed to sell on ebay because they were labeled as selling copies of other people's products (or something of that sort), so those that are currently on ebay should be pretty similar to SSAC

I gained roughly 7whp going from a hotshot gen 3 to an ssac 2.5 header & collector a while back... the header was the only mod I changed... take this how you want though. Sorry the scales are all jacked up and its not on the same sheet... i had my gripes when they were printing it out...

On their page they are saying "2.5" outlet"

If the product is the same as in the pictures then you should be good. My SSAC header looks to have the same sized down pipe

Just in case email the seller

The best comparison to OEM one that I have is here:

like covert said, WATCH how its listed, you could definitly buy something that is worded lik you want, but in reality its completely different

2007-12-26 18:49:19
