Evening all,

I'm currently running a full decat (2.5) with a Ninja 2 back box. I'm looking for a more track friendly back box, (for silenced days) if I can get away with just changing that. My current tail pipe is 4.5" if I remember rightly.

Any suggestions?

Cheers

 

Silenced days? Is there really such a thing?
Why on tracks does it matter? A jobsworth involved somewhere along the line I'm sure?

Typical Bullsh1t Britain.

 

H&S system is quiet but raspy and awesome on boost! I love mine it makes the Scooby sound motorsporty without being too loud and droney! Think I made up a few words there but hey it's Xmas lol

 

Hi pal, I have a back box that would be track friendly not sure on a make and it looks a little tatty but it works well if you're only using it on track. Give me a pm if you're interested

 

Thanks for the offer Blue and Gold but looking for a more day to day system with the added bonus of being track friendly.

 

No problem mate hope you find what you're looking for

 

Got a full 3inch revolution system on mine passes db checks

 

I like my prodrive back box, but i'm not into loud exhausts after my full decat miltek too much noise for an old man like me.

 

I believe japspeed or cobra did a 3 inch system with two boxes. It's still a performance system but more subtle sound & track day friendly. Failing that I have the H&S scoobyworld racebox exhaust & it's very quiet but still has the flat 4 rumble without being intrusive.

 

get a jetex silencer fitted to your current system? cost you a lot less

 

Cobra 'Trackday Friendly' 3" system mate. Great sound without being OTT. Had mine on a fortnight now and well chuffed. Nice burble over standard OE system.

 

Just stick equal length headers on. Job done

 

We like the Jetex system, it has a nice big back box, and we've run one over 680 bhp.



They do a full decat. We can supply with a discount if you fancy one.

Give over, millteks not too noisy, in fact the opposite until you floor it

 

i like that

looks well made too

how much is that for a newage ppp downpipe back ?

siv

 

Do you know what the DB rating is on these too? As well as a full decat price?

Cheers
Andy

 

I've got a custom back box that is super quiet but run the RCM resonated centre section; biggest resonator I could find on a 3" without having to go custom. Hth.

 

Jetex looks. A nice system. Is it 3"?

If you can afford it, go to Matt @ Simpson Race Exhausts and have a bespoke system built. I love how quiet mine is.

 

^^^^^What Frayz said
Matt made me a centre section which clips in and out in minutes
Knocks around 7db off mine

 

Thanks for all the tips lads, after just getting back from watching the trackday (circuit is local) I think I would have been alright given what some of the people were running!
