i think i might have an issue i have a 97 ek hatch and my exhaust just came in and its the apexi ws2...i was looking at the exhaust and my test pipe has a triangle flange but the piece closest to the cat has an oval shape flange on the ws2 piping...anybody else have this issue?

 

uh oh, prob gonna have to go to an exhaust shop and get them to weld a diff flange on to make it fit

 

yeah i was thinking that i might have to do that...im wondering if maybe they sent me the wrong pipe..my ws2 for my integra had a triangle shaped flange on it..any feedback people?

 

is the stock cat different than the test pipe in terms of the flanges?

and what are you gonna do about the CEL?

 

x2 i think thats what your goin have to go do.......

 

you wont need a test pipe as the cx dx lx 96-up civics have the cat on the header and the pipng bolts up straight to the header. so when you get aftermarket header it will delete cat

 

well i got the hytech style header so its about 4 inches longer then most headers..but the flange on my apexi piping isnt big enough to bolt on to my header because its 2.5 outlet....i was wondering if the 99-00 civic ws2 piping will bolt right up to my car or is it longer cause its a coupe.

 

you can't use coupe piping to bring it closer to the header because after the S bend it is longer and it'll stick out too far.

 

coupe piping is shorter so it has room for the cat and the si piping is the same size your gonna have to go to a exhaust shop and have them weld on a bigger flange

 

i guess im gonna have a shop weld on a triangle flange on my piping and shorten it a bit so i can bolt on my test pipe

 

yea thats the easiest way
