Downpipe

[tg1]

i had an obx manifold for my yaris, was meant to be a good fit, judging that it used the oem heatshield and all the others even the trd manifold did not.

Dunno if it helps but they're pretty big over in the us, as is megan racing

Yeah but topher, does the downpipe you recommenced fit exactly without any modifications?

[topher]

well it's the same one r-tech used to fit to customers cars before they got their own made up, and i don't recall any fitting issues..

[Payne]

Would it be better for me to get the 2.5" or the 3" ?
Since I'm not doing a turbo upgrade
I'm getting it mapped though next month, don't know if that has anything
to do with the decision.

[tg1]

not sure but i'd assume the bigger the better? would it fit onto the standard centre section and manifold?

2.5" is fine...
