looking for a full system and downpipe for an S2 with a small amount of head work and probably running a T34.

what system, bore size and backbox gives the best performance?

 

Mongoose 2.5 inch bore m8 is the best for a few added ponies for an rst with a choice of 3, 3.5 or 4 inch outward rolled tailpipes, personally i have a 4 inch tail as found the 3 to small, magnex are no longer running so i hear and scorpions are restrictive

 

Depends on power, but I'd say a 3" bore Mongoose for a T34.

 

what power you going for kev
this your track car your building?
you still no finished that

 

ive got a full momgoose with 2.5" bore and 4" outward rolled back box and its very good and burbles very nice

 

any one got the mongoose evolution system was thinkin of gettin it

 

you know it

it's for my S2, still have the XR3i shell that i'll track one day, would rather get the S2 sorted first.

looking for anything over 200bhp atw, using a 1900 on a T34 with Cossie Management. I'd rather keep it driveable and try to make the engine as strong as possible so its built to last. Not a good start using a tall block

i fancy the 4" outward rolled but wasn't sure on how big/small to have the bore, was thinking 3" but i've been offered a 2.5" for cheap cheap

 

that's what i'll go for mate, advice noted

EDIT: that wink smiley is a bit gay, sorry!

 

for 200atw id put on a stg 3 t3 mate,the t34 will be too late coming in and will not be nice on the road.youll see over 200atw still with a stg3 t3 and have good power low down,a 2.5" bore will be ample at that power mate.
