Nice crack in stock manifold
LOL this is getting funny now................well today I found a nice big crack in my exhaust manifold header 
just another thing that needs replacing. I'm not looking to spend a ton on this car........YET. Can someone recommend me a set of headers to band aid this until I rip the engine out and go turbo? I know there are a few on Ebay, but not sure of the quality...........................well I have an idea of it 
. In research I read that some of the IS headers will fit the SC300, but still unsure

The IS headers will bolt up to the head but will NOT bolt up to the stock exhaust. You have to get some piping done to fit the header. If you are looking for an after market alternative you are going to have to re-do that section of piping also. The MVP header would be a good choice. I run it in one of my SCs with no cats.
Also, depending on what year SC you have, you have to use the IS style O2 sensors. Same rule applies to aftermarket headers.
