Where is the best place to order from? Will I get raped shipping to Canada I wonder lol. Is there any reason to DL grimspeed over new stock ones from Subaru?

Thanks again.

I ordered the ones open flash sells. These prices seem pretty expensive just for gaskets but oh well. Figure best to get the whole package from one place....that way I'd something doesn't fit together...

Truthfully just worried about it being obnoxiously loud for daily driving. I could put my stock front pipe back on but hate opening up the header only to close the system down the line. I want the best gains and catless is the way to do that but at what cost. So if anyone has a catless header and a catless front pipe what are your thoughts? Thanks all

Don't waste your time with a catted header if you are most interested in gains. Yes you may have to play with your exhaust to get the sound you want but their are plenty of options for you to choose from if you want the gains but want to keep it quiet. I have the q300 and OFH on stage 2 and its super quiet. Almost too quiet.

With OFH and OFT stg 2 the car is more snappy. I will never go back to stock after driving the car they way it performs now.

Putting your OEM front pipe back on will help. Or you could try the catless front pipe and just get a quiet cat back like the q300. I am actually considering selling mine in exchange for something louder because with my OFH and q300 its not loud enough!

The grim speed ones are really thick and look a lot nicer then the oem ones. In my humble opinion worth the extra amount.

Yup and you can get gaskets for the entire exhaust for like $20 more than the three u get when you purchase the gaskets that are sold with the OFH. The gaskets they sell with the header are a bit pricy in my opinion but I can't fault them on that price when they are selling this amazing header for nothing.

The oem gaskets really do cost that much though.

If your only replacing the header then yes just those two. Make sure the gasket in the top image comes as a pair. I am sure it does.

Damn its 30 bucks to ship to Canada plus 38 for the gaskets. What a rip! Wonder if scion stocks the OEM ones? I mean if it works for stock it should work for this right? These are just "higher quality" or thinker right?

Thats what i like to hear, and the more i started looking around the more i think ill be ok. I already ordered the header and running a tune from the OFT now! Just waiting for the header to come, pretty excited about hearing and feeling the difference. Thanks for the post!

[fenton]

@shiv@vishnu do we phantom sc guys need a new tune when running the header with the ESC for better gains?

This is the rear gasket that I purchased per GrimSpeed:
