Poked around here and the civicxi Type-R forums and didn't see a comprehensive downpipe thread. Thought we could use one. Mostly selfish as I want the community to aid my research as I shop for one :p.

What I've rustled up so far is in the table below. All info and pricing is from the manufacturers' sites. Using immense willpower, I have kept my opinions out of the table. As y'all find more, post the links and I'll update the table.

An added bonus of the TSP DP is that they have a no CEL guarantee. I think all the others will throw codes if you don't have a tune. Something to keep in mind.

I want opinions! I've basically settled on the Two Step option, but it's not cheap and they say 8-12 weeks for delivery. Anyone have a good experience with other options? Maybe an intercooler down the road but basically all I'll have is intake, tune and downpipe for now.

Advice?

I was thinking 27won also, and somebody said no, get TSP. better quality and will stand up better on the track.
