alright all new to this ,this is my first real post would a standard 1.5 civic (b pipe) be bad on a civic with a 1.8 sir engine with ITR cams, AEM intake ,and a SK2 intake Mani ,as would that exhaust make much of a difference to the performance of the motor if so I will change it as the pipe from the cat back to the back box is only a standard pipe of a 1.5 lsi so it prob only 1 and half inch in diameter maybe

cheers people
 
it would be very restrictive and causing alot of back pressure. get a good 2.5" system somewhere!
 
i'd be looking a 2.5" system from the manifold back. Not just the b pipe....
 
alrite true man would make more sense that way thanks for that man appreciate it cheers
 
ull notice a massive difference if you go 2.5 inch mate,urs is massively restrictive
 
cheers man ill get one for it just dont want it to be 2 loud just to be nice in vtec you no cheers
 
mugen twinloop on here forsale atm it would be perfect,not to loud but nice note off vtec
