As title guys my hawkeye has a 3" H&S down pipe, with a cobra 3" system, i love the angled exit on my old classic scooby, managed to get hold of a kakimoto from a 2005 Spec C. and it appears i would need to remove at least 4" from the centre section, so would i need a different downpipe or would i be better getting a new centre section made up ( that's assuming i can find some one who can make me one up locally)

The 2005 SpecC has a "similar" turbo back exhaust setup to the UK Hawkeye, so in theory should fit without modification.

MY05 SpecC




MY06 UK Hawk



It was only when you start mixing the 3 part JDM and 4 part UK exhausts you end up needing to use a different centre section

Checking the part numbers, both use the same centre section 44201FE040 (item 30/44102BB)

Get what your saying mate (BTW thanks for the reply) however as i'm changing the full cobra system for the full kakimoto system, i assumed that it would be a straight swap, i'm not trying to mix and match, my thoughts were that perhaps the 2.5 UK uses a different down pipe to the JDM one, checked H&S website and they don't show different downpipe for 2.0 as opposed to 2.5, so i assumed they were identical, but when i line hangers up it looks like i need to remove either about 100mm from either the downpipe or the centre section

I have just been to Haywood and Scott in Basildon to modify my downpipe and cut out a resonator from my invidia centre section very good service maybe worth a trip down bud 👍

wish i was close enough to take advantage mate, but as i'm top end of lancashire were the M6 is cobbled essex is a tad too far

H&S downpipe (including 2nd cat pipe) for 2.0l and 2.5 L will be the same length.
Assuming your UK vehicle has the correct model year downpipe and cat back exhaust, it suggests that if you need to shorten the centre pipe by about 100mm, the Kakimoto full cat back is actually from a MY04 SpecC which had the 3 piece (classic style) JDM exhaust system where the donut joint is nearer the front of the car and has a longer centre pipe.

Easiest and probably cheapest job would be to shorten the centre pipe to suit rather than replacing the downpipe.

dan but your good don, its almost like walking with Yoda, id assumed that the spec C was a 55 as that was the plate it was on, seems your right, only problem i now have is finding someone who will chop and weld the centre pipe, i have a local exhaust "specialist" who wont even look at it, anyone got any recommends, even if i have to travel a bit to get the work done ? again Don your help is much appreciated mate thankyou
