back of hols

i have just brought a backbox but its got the bigger pipe and i still have the 2.5 system

can anyone just sell the system minus backbox for s2

 

i thought it woz 3" the next one up?

 

i have the 3" back box and 2.5 system

 

wot i mean is that mongoose do two different bore types for there systems.. 2 1/2" and 3"... then wotever size back box you want with that...
they never done a 3 1/2" bore system for RST...

 

sorry il explain


i had a 3" tailpipe with 2.5 system
now i have a 4" tailpipe which was on a 3" system
i still have the 2.5 system so its too small for backbox

 

can i but just the system minus backbox 3" one

 

oh now i get it.lol
yea you an, but the system comes to more then the backbox...
if you look at at a website you find that a brand new back box only costs bout £120.
i would sell that one to someone who could use it and buy a 4" version for the 2.5" system..

 

Can you not just get a fitting piece ?

4" --> 2.5" reducer ? Or is it you want to change the whole system too ?

 

will it restrict or fook up gasflow????

can find reducer if i tried

 

it will be 3" - 2.5" reducer

 

You have a 2.5" system at the mo if I read it correctly, fitting a piece in to increase it to 3" at the back box end shouldnt cause any problems.

Im sure I seen them in one of the bins when I was last in there workshop

 

what u may have one
