Just purchased a Cobra back box online - anyone know if they sound ok????
 
Its a cobra sports exhuast 4'' tail pipe got it brand new off some guy on ebay? any one know if they sound any good?

Very loud (esp with centre and decat). I had a full 3" Cobra system with the 4" rolled-in tail (+ decat) and it's loud like a Nur Spec or Firestorm is....

harrisonl84 21 July 2010 10:24 PM

well ill still have the cat in and not 3'' all the way through so im assuming it wont be to bad?

joz8968 21 July 2010 11:50 PM

It'll be muted-loud LOL

harrisonl84 22 July 2010 01:24 PM

oh well as long as I get a buble il be happy my exhaust I have on now is very quiet.

joz8968 22 July 2010 01:29 PM

Oh it defo magnifies the burble alright! ;)

It will be significantly louder than a very quiet exhaust (really?! lol), but it's not as if it's stupidly deafening or anything like that.........

haha I can live with that ;)

Ive got a 2.5 straight thro including decat and a 5inch cobra back box = very very loud, sets off car alarms :lol1:

harrisonl84 23 July 2010 11:40 AM

Oh dear lol, surely it wont be that loud with just a back box?

It is v. loud for just a back box. But not as loud as if you also had the straight through centre and/or decat d/p, obviously.

Has your b.b. got the 2.5" inlet pipe option, or the 3" one? (I'm guessing the 2.5" one, as I don't think the 3" mates up to the OEM centre section?).

If so, then Cobra state that their 2.5" b.b., - and systems - are appreciably "quieter" ;) than than their 3" ones...
