Hey guys i made post a while back i have an ek9 swapped b18cR with 5zigen 4-2-1 header which is flattened a custom stainless steel testpipe and a custom 63mm stainless exhaust with a twister muffler engine is stock no ported head or cams or pistons or anything only bolt ons and tuned with power fc ecu i decided to get original toda ver.2 4-2-1 headers for b18c but im struggling to decide for an exhaust system what are your thoughts
 
What do you use the car for? Is it a daily driver?

Are you looking for max power or a refined tone?
 
Daily driver not many kmh though home work etc about 150 per week as i said ill get toda original header i pretty much use the car for back roads and corners touge style i thought of the js racing c304 system i mostly want mid range and high rpm range power
 
A 2.5" system for all out performance.
A smaller diameter if you want to keep sound levels sane.
The Mugen Twin Loop, Apexi World Sport II and RS-R Exmag cat-backs seem to have a really pleasant, refined sound if you want something more grown up / liveable...

:beer:
 
2.5" atleast if that's what the toda header's collector is. I'm not sure if a smaller diam exhaust like a 2 and a quarter would make much difference noise wise, if its too loud add a silencer in. Think their about £30 off ebay.
 
I've got a Toda replica header on mine and a custom made 2.5inch exhaust system with a decat fitted. Its not loud at all at cruising speeds, comparable to oem tbh. It only gets a bit loud when you floor it.

You should definitely go custom made exhaust system. You'll get what you want and it will be a perfect fitment. I asked my fabricator to get it as quiet as he could and he did a perfect job. I went to Solid Fabrications in London if your interested. Alan there is a top man and will cater to your needs; the work he produces is second to none.
 
I have a titanium j's racing 60rs catback, the noise and weight saving alone justify the price tag imo! Amazing system

It makes a significant difference in sound levels! Not such a huge loss in performance though...
 
I would suggest fujitsubo legalis r, spoon street or mugen twinloop which are all great systems and quiet enough.

I also have an rsr 4-2-1 manifold and very good quality along with the fujitsubo manifold too.
 
Mugen twin loop if you can get one, I've got one with a straight through centre section and it's not that loud! Going to get a silencer put in centre section though.
 
Tanabe make some quiet systems too, I've tanabe hyper medallion on my ek, it's reasonably tame when cruising around but sounds lovely when hooning.
 
I think ill go for a full js racing c304 60rs and the toda manifold although i found a manifold and back mugen exhaust system for a pretty cheap price but am afraid of losing power
