EK4 exhaust on an EK1

[davechung]

Hey guys is it possible to directly bolt on a remus exhaust from cat-back which was off an ek4 on my ek1?
Cheers

There are a few things, what sort of ek1 do you have: hatch or sedan? Also I assume that when you say an ek4 you mean off a hatch?

I dont think it will be a direct bolt on as I am pretty sure that the ek4 used bigger exhaust piping. It really depends on if flanges were used and what size they are.

i recommend 2&1/4" b pipe with x force muffler with 4" opening
ahahaa

should bolt on but if the ek4 had a 12 fin cat then it wouldnt due to the different lengths of cats (ek1 6fin) might fit i havent tried tho

i have a 97 gli hatch
fins?
never heard that term before
hmmm thanks guys

the catback won't be straight fit. the cat sizes on the ek4 and ek1 are different. But if you can get your hands onto a ek4 cat with the catback, it'll be straight bolt on.

note. the fins his talking about is on the cat, i believe he was just using them as a reference to the length.

sorry guys i asked a similar question before but now its more specific
ur help would b greatly appreciated.

Is the stock ek1 b pipe the same as the stock ek4 b pipe?
ie can i use the stock ek1 b pipe on the stock ek4 cat and ek4 axle back?

is this confirmed?

is this confirmed?

I have never tried it, but from what I understand the ek4 uses bigger exhaust piping to accomodate the b16.

[type one]

EK4 stock piping 2inches... EK1 stock piping is 1.75inches or thereabouts.... which would necessarly mean the flanges on the two pipes differ as well.

You won't know until you hoise the car up... so hoist her up!

That being said, you could always put a transition flange into place and that would mate the two systems together.
