Do all D-Series headers fit?

yep, all d-series parts will swap right on over. just make sure you get a new gasket and you’ll prolly need to do a lil custom work on your exhaust piping cuz the y7 has the cat coming right after the header.

Are D-series and B series headers the same?

in order for there to be any real comparison you need to pick which D to which B series header. All B’s are not the same. different DP length’s and different heights.

Are all D-Series starters the same?

d-series starters are all the same. the only difference is the auto and manual ones.

Are B series headers interchangeable?

All b series headers are NOT interchangable. If you have a B16 header it should only fit a b16. A b16 has a shorter deck height therefor having a shorter tube design.

Why are the headers in the D series not sequential?

The concept is to keep the exhaust gases flowing by not having two pulses enter the collector at the same time, which would cause excessive back pressure. This is called non-sequential pairing, and most of the D-series headers below apply this design concept.

Which is better rs-r or D-series headers?

What’s the difference between GReddy and 4-2-1 headers?

Similar in design to the other 4-2-1 headers discussed, the Greddy header will be a bit heavier given the two-piece design. Also note the relatively short primaries for a 4-2-1 header, meaning maximum power output is pushed up the rpm range. The merges to the secondary runners and the collector appear a bit abrupt.
