Is it true that JDM Type R header only come in 4-1?

I just had a JDM Type R motor swap done and a 4-2-1 header came w/ it. I was later told by another person that the header I received was a CTR header. Could this be true?

Also, is 4-1 made for high gains while 4-2-1 is made for low gains?

 

That's a pretty general question. It really depends on WHICH 4-2-1, honestly. The TODA 4-2-1 makes power EVERYWHERE, as do many others.

I don't know enough about the CTR header to tell you either way, but the JDM ITR is a 4-1 w/ a 2.5" collector.

 

Say we're comparing a DC JDM 4-2-1 to a DC JDM 4-1. Which will give me more low gains, high gains, etc?

 

4-2-1 low gains, 4-1 high gains.

 

um i dont think DC makes a JDM 4-2-1

 

so if i get the DC Sports JDM 4-1 header w/2.5in collector...do i really have to get a 2.5 cat and 2.5 piping all the way??if not...any other choose??

 

you'd have to at least get the 2.5 inlet on the cat to make it all fit. its up to you if you want 2.5 all the way through.

 

A 4-2-1 header will give more gains in the mid range and the 4-1 will give more gains in the top of the RPM range.

I am not sure if there was a JDM 4-2-1 ITR header or if the CTR header was 4-2-1. If the CTR header was 4-2-1 then I would make sure the engine you got wasa 1.8L and not the CTR 1.6L...and don't just look at the tranny stamp because they coulda swapped the tranny.

 

whats your engine code? and if you have a typ r motor i would go with 4-1 header because it makes like all its power in high rpms any way

 

At some point i'd like to get Spoon's header, but it's a lot of money. It's a great header. The design and make of it was thought out and tested very well. Plus it's Spoon, anything Spoon is good. heh.
