I have an ek hatch 1.3 auto wit a broken sport muffler, the previous owner removed the testpipe/resonator i don know what u call it n i'm going to replace the thing. I managed to find a eg6 muffler for my ek.

question. will a straight Bpipe without the testpipe increse performance n save a bit of mileage or not.?


SORRY

 

performance maybe a little bit...save gas mileage; maybe not...you cant really have both

 

2000+ dollar ticket here in Cali for haveing a modified cat and yes you can tell if you have it or not. The smell is very noticable.

 

Just noticed your from Malaysia... you probably don't have catalytic's on your cars.

 

no. we all have it on our car except they change it to straight pipe. so everyone still agree to have the testpipe n stock muffler.?

 

unless you have a turbo you may loose power, depending on how big the test pipe, stay stock unless you can supply all the sufficient mods to make it work. non turbo cars rely on a certain amount of velocity without a cat theres too much.
