3sge header to 5sfe, how much of an improvement and will it bolt up? Options

[goferris]

hey all. i've been thinking about getting a header for my pretty much stock 5sfe and have seen the headers on ebay but realised that the 3sge came stock with what looks like a pretty decent header.

i was just wondering if it would better to get a stock 3sge header with the heat shield already attached vs buying a cheap header off ebay then wrapping it. would the performance boost (however little it may be) be about the same?

also i'm pretty sure it would bolt to the engine just fine but how about to the rest of my exhaust system and would it fit in the space there? i'm sure i would eventually just get a whole new exhaust system header back but in the meantime will this fit before hand?

another reason i ask is because i was chatting with lewfx the other day about getting a header and he said it really heat up the engine bay when he had one on his celi. since the 3sge header is a stock one with the heatshield i figured it would be a little bit cooler and a lot better quality than the ebay headers.
TIA

a 3sge header will bolt up to a 5sfe head.
is the stock header already tubular on your celica?
the only reason i ask is it is on my '99 camry w/5sfe & i'm unsure if it's the same on a 6th gen celica.

honestly, the 3sge header isn't going to give you a big hp bump if your stock header is already tubular in design.
maybe 5hp - 10hp at most, same thing with an ebay header.

if you're concerned about heat in the engine bay, have the header ceramic coated - its not that expensive to have done.
