hi

fitted a 2.5 inch sports exhaust to the ef fairmont and yet to fit the extractors.

and while it does sound nicer just want to know if fitting the extractors with the std cat converter will change the sound as well

unknown but in my opinion get the cat changed to a sports cat, you will notice the difference.

i fitted a 2.5" lukey exhaust an it gave a nice smooth note then i fitted pacemaker extractors 4499's and a gutted hiflo cat ( came with the extractors and didnt wana pay some one to mod the std cat to fit lol ) and that has made the exhaust MUCH louder and given it more of a harsh note to it, sounds kinda like a great big dirty V8 when under load....how ever i havnt put my extractors on right yet ( atm there just a test fit ) and they are leaking as i used all original gaskets...that might be why im getting the harsh note...but all you can do is fit and see :) but i did get a massive power increase in the higher rev's..:) beat an old ED V8 today and kept up with a VL turbo :) lol

the std cat has to be cut and welded to fit, and the cat sit about 25cm further back then the std one too.

if you got the short extractors that just has to have the cat converter pipe at the manifold end shortened how do you join a pipe with a flange already on it without welding
