right then .
what do you all think about the estimated power increse with exhaust systems???? for example
exhaust manifold ..up to 30 bhp
turbo up pipe up to 15 bhp
de-cat down pipe up to 30bhp
de cat center section 10-15 bhp

i mean going by what these people are stating you can get up to 70,80 + bhp from a full system manifold back to back box...
what do u all think about this??
are any of these figures corect or are they just sales talk???

 

Recon someone is having you on.

 

 

thats why we see the 300+ bhp scoobies on ebay with only a aftermarket exhaust. Of course we all know is bullsh*t.

 

I reckon in reality, the increases on a standard car are less than half of the figures you've posted

 

Sales talk. You may get ~20-30bhp max increase from a full decat (without a remap).

 

lol just what i thought.
find these figures all the time even looking on ebay now there is loads of them lol

 

Only 15bhp increased on my mate P1 with all fitted (dyno proven)
exhaust manifold
turbo up pipe
de-cat down pipe
de cat center section

 

yea that sounds more like it to me..
i was thinking up to 30 bhp extra fot fitting manifold back to backbox
cheers for your help
