Tempted by one or the other. Surprisingly, I want which ever one is quieter.

So which is it?

 

Much of a muchness i believe....it'll come down to which look you prefer. I have the Ninja and i love it!!!

 

am i right in thinking H & S make the ninja .....

 

Slight hijack.

Also thinking about a Ninja - is there any point in buying the centre-section for a new-age if it doesn't remove any of the cats? Is the back-box on its own enough to give a few extra HP? (Plus a filter, obv)

 

nope wrong there... just read about the ninja....

 

H&S make the vortex according to the scoobyworld website. It doesn't say who makes the Ninja.

I can get the H&S supplied and fitted locally, but the Ninja would need to be ordered in and then I'd have to find somewhere local to fit. Which wouldn't be that hard really, but I'd like to get it all done in the one go.

 

Another for the Ninja. Love it. Very quiet within the cabin..

 

Hayward and Scotts website says they can 'tune' the exhaust to sound pretty much how you want it so it might be worth giving them a call.
Have you considered a Prodrive backbox as they give a nice rumble without being overly loud?

 

Another vote for the Ninja here

Got it on my MY05 WRX looks the dogs danglies,but doesn't sound
loud in the cabin at all, but gives off a nice sound when you squeeze
the loud pedal

Oh and definatley give some extra horses !! had to put my standard one back on
for a while the other week, what a difference !!

A vote for the Ninja from me, recently DIY fitted to an MY04 STi. Came with bolts and a gasket and took around half an hour. The hardest part being the rubbers but some lube soon speeded things up.

Lets not enter the warranty debate but watch out for insurance issues - Direct Line count it as a mod. Honesty could pay when the need arises etc.

 

The Ninja is made in Japan, they don't say by whom, but by a manufacturer who make for many big brands....rest assured the build quality is great.

I have the afterburner centre section on mine purely to remove the resonator box so it's a bit louder....don't know what BHP claims they make but without removing any of the cats i can't see it could ever be more than 5 tops, just cos the flow is a little better.

Get a full decat, you know you want to

 

i had a ninja on my old wrx and loved it! just wish they had made them half inch smaller!

 

Liked my H&S handmade, great quality ; considered ninja. I had ~3.5-4 " (exit)- too much after a while ( nice tho). Id go for stainless 2.5 "(exit) or similar if i were to do it again ( the car actually makes all the rumble you could want without too much enhancement).

 

H & S or try TSL

 

Either option sounds like a winner. Now which one to go for!

Actually, I like the angled exit on the H+S, think I'll have one.

 

s'what i got....

 

Dunno which one one is quietest but have a Ninja on mine and it sound's the dogs danglies when you boot it !
