I have a Prodrive backbox at the mo but wanted more volume and grunt.

After reading ppl's comments it was a toss up between Afterburner and Ninja but was offered a Ninja which I was happy to purchase.

To be honest there is hardly any difference which was disappointing.

Is there a noticeable difference in the Afterburner & Ninja? If not will I have to opt for an exhaust specialist to custom make what I want

Any help or suggestions will be appreciated

 

afterburner is a better burble imo.

decatted system would help greatly too

 

cobra race tube would be better rob

 

imo a backbox alone wont make that much difference

 

I have a ninja but it's the ninja 2 model. Much nicer sound than my stock pipe, highly recommend.

 

Get yourself a nur spec

 

Get a Ninja II cat back system - thats plenty loud enough. My mates can hear me turning my car on and they live the next street down!

 

Do you still have a resonated centre section, The bit before the backbox, If you put a non-resonated one on this will improve the sound without removing any cats

The afterburner is loud once de-catted but not sure how it sounds with cats on.

 

that's nothing, my mate can hear me fire up the nur spec 1.5 miles away!

 

Std ninja backbox does not sound the same as a ninja2.
The ninja 2 gives a nice bassy soundtrack on tickover and when fully decatted gives a nice growl without being ott when you get your boot down.
Afterburner vortex roars and is LOUD fully decatted + pops & bangs with no remap needed + occasional flames I have only recently taken mine off , just so I can start listening to my Sony system

Afterburner vortex:









My old ninja2 back-box



Both backboxes have the option of fitting a removable bung which you can buy to quiet the system down for early morning/late nights & it works. However I never used it on the ninja2,but it is a MUST on the afterburner lol

 

The problem isn't your back box but the standard centre Pipe I am guessing you still have fitted. You will need to get a dereasonated centre pipe fitted if you want to improve the sound, it won't be a problem come MOT time or need a remap either as you will retain the down pipe.

 

i agree with midnight,

i have had the Vortex fully decatted, an wow what a rumble & noise, very nice. I now have the Ninja 2 and it sounds exactly as he descrribed, nice burble, not intrusive but does roar when you put your foot down, again though thats with a decat pipe.

However i have always used a after market resonated centre. Vortex had a scoobyworld resonated centre & current scoob has a Cobra resonated centre.

p.s midnight - you selling your vortex b.box?

 

If you want it to be noisey you have to get the cats out of there.
I have a ninja 2 fully decatted inc. uppipe and its 97db+ @4500 revs. (not exactly quiet)

Having said that, the afterburner is a way louder exhaust (horribly loud if you have any motorway miles to do, IMO)

 

When I had a prodrive back box and changed it for a vortex with the std center section, it was so loud that I would try to free wheel down the parade in leamington because I was embarraced to touch the throttle as people were looking around 50yds away . After a while you get use to it, but fully decatted it's an animal . I am on my 3rd afterburner vortex and I love the sound.
Timmy not to sure about selling it at the momment , but I do like the sound of the fujitsubo system I recently fitted,as it 3' & Not loud at all and sounds more like a V8 when your giving it plenty + you can have a normal conversation at 120 mph

 

I believe I recomended the Afterburner even on a standard car it sounds great cats are fine but a de-res centre section is a good idea

 

decatting made a big difference for me. i have the ninja replica exhaust and yes it was quite before the decat.

 

When you say decat = more sound, are you talking

a) up-pipe
b) downpipe
c) midpipe
d) all of the above

 

on a classic, to me a 'de-cat' is the cat from turbo to centre pipe. put an open mouth 3" bore decat pipe in & have it to suit eith 2.5" or 3" to suit the rest of the system.

middle pipe, not sure what a std one is as ive never had a std on my scoobs, but i have used resonated ones just to stop the drone in the cabin when motorway cruising, does not make a massive difference but it helps.

can not comment on up pipe as i have never changed them. i believe changing these especially for Harvey ones, helps spool up from memory. Do not think they would make much if any difference to the sound on a classic by changing it.

but with you having a newer version, it could do

 

only newage wrx have cat in uppipe.
Removing that does make it a bit louder and made mine pop and bang a lot more.
Turbo back decat makes the biggest difference to the sound.

 

Even the Prodrive back box will change soundtrack, once the rest of the system is decatted.

 

had just a prodrive bk box on my classic was far better than standard. but then fitted a HKS hi power system.loud aint the word! i f!&$%ng loved it!

 

My Prodrive back box is fairly loud but then I’ve got a straight through centre section. I did have a TSL firestorm on the car but it was far too loud for me....so maybe a TSL Firestorm with a straight through centre section is what you are after??

 

I had a decatted prodrive system with sports cat on my bug, De-resonated centre section with afterburner back box and it was about 105 DB @ 5k rpm
