Good to know, but I still can't get over that shitty collector design...

I love my Megans. Seriously though, the placement of the O2 bung isn't that big of a deal. I fixed that situation in 5 minutes with a hammer.

Random question, is it normal to smell gasoline after header installation? I just slapped on a toyo header to try it out and only annoying thing is the smell of gas...

Normal due to less burn off and less restriction of the complete exhaust system....

got my megan header and y pipe, did a quick mock up and.... not to bad, but damn these flanges are not flat. Warped from welding, probably why many have problems with leaks.

I'm going to try and using something flat with sandpaper, to square them up.

any good pictures of where I should weld a O2 bung in?? I'm fairly sure I know where to weld it in, but a couple pictures would help, as I want to weld it in and take header for ceramic coat.

Hmm I'm running the toyomoto header and y pipe with stock b pipe and hks dragged 2 cat back. Dam, so there's no solution for the smell...I've read people welded their y pipe with their headers and a good portion of the smell went away, might this work?

That would help . I'd only do it if you don't plan on changing your set up and don't mind welding them together.

I am having the same problem i got about a half of an inch gap, going to machine them down and that leak blew out the gasket for the header to the y pipe so i gotta fix that too at the same time... post up how yours went.

I didn't get any before pictures , but here is some after. Took me about 3 hours on my belt sander, can't really tell from the pictures but it's alot better then when i took it out of the box. My y-pipe is probably a knock off cause theres no megan logo on it, got it on ebay.
I'm also going to try this e-vac fitting from vibrant, going to try and put it just after y-pipe merge if it doesn't hit the under side of the car.

You need to have very low back pressure in the exhaust for those to work at all. On most exhaust setups they end up making things worse.

In 5 years I will have the worlds fastest IS300... because everyone else will have parted out and bought an M3.
