Xforce Twin Loop + lose power

[kelviN]

hi i just installed a 2nd hand s12 twin loop muffler onto my civic vtir and i have noticed low end to be losing power. Is this possible or is it just my imagination. Piping size im not too sure but its around 2 inch like standard. There is also a fuel smell problem like in one of the old threads here.

didnt no much of difference really.. its jus a muffler = noise

yep axle back. What size is your piping?

It's probably my pod that lose low end power.

[mrwillz]

fink its 2.25 or even jus 2
stock size is 1.75?
axel back wont affect to much... its the last straw of the exhaust.

imo the twinloop does seem to be a lil bit restrictive... but u should be losing topend power instead of low end.

i used to have a s10 and s12 and now i've just got a straight thru and it revs out a lot smoother.

top end dies in the arse.
low end was very slightly improved.
i focking hate it.
lol.

Axle back WILL affect a cars output significantly , if the muffler or piping is significantly restrictive or free flowing.
I think the X force "copy" muffler is restrictive :)

hmm....wat im feeling is probably the extreme hot weather + exposed pod. Will put entire stock intake system back in......and see how that will feel:thumbsup:

well, quiet is usually more restricitve

hmm...i have installed my entire stock intake system back in...and it seems it was the pod. Must have been driving much faster n more torque cars....makes my b16a feel very sluggish.
