I have a 4 door integra. Anyone know what I have to do to get this cat back to fit?

4 Door LS is the same as Civic coupe/sedans that DID NOT have the cat in the manifold. GSR is a whole other animal.

No idea, You would have to get underneath, mock up the exhaust and measure what needs to be added.

If the EX/Si exhaust is the same like mentioned you can use one of those as reference.

I installed one of these for my buddy on his 94 rs and I was not very impressed with how the muffler sat. It looks kinda crooked. I measured the inner diameter of the piping and it was smaller than 2.5" I believe it was about 2.36. I can't speak to the sound because his exhaust had multiple leaks in header and cat.

+1.

i run 2.5" piping with an ITR muffler.

I own a Yonaka WS-II exhaust and i love it!!! I have modded mine and removed the tip which caused a annoying buzz. Went away with a smaller tip. Added a 24" resonator to get it even more quite. You cant even tell my car is running at idle.

i dont have a yonaka, but i do have a greddy mid pipe for 4 doors, and a ws2 bolted up to that on my 4dr gsr

i had to do some tweaking, but i got it to fit, the tip is tucked under the bumper though

I have a drive by clip when I had my integra. Skip to 1:43 for full throttle pass.

B-pipe was extented 4 1/2" to compensate for GSR header/cat. Stock airbox, OE spec cat, and stock exhaust manifold.

Forgot to mention, I have no test pipe or cat. My header goes straight into the midpipe.

With the resonator, that exhaust must be very quiet. I also have this system as well and thought it was a lot quieter compared to my older N1 style. Overall, satisfied with the quality and price.

For a 4-door, the midpipe would just have to be extended a bit...simple job @ muffler shops.

FYI All 92-00 civic and 94-01 integra use the SAME exact length midpipe (from behind the cat to front of the axelback.) the differences come in if you try to use a regular length cat on a 94-98 gsr(these have longer cat converters).

only other difference is in the different axelback tip lengths. All 92-00 civic coupe/sedan catback will bolt right up to the integra sedan. The DC2/4 however has a shorter rear overhang so civic coupe/sedan tip would stick out too much.

Personally I was very satisfied with my Yonaka Exhaust. I purchased it over a year ago and it still sounds as good as it did the day I installed it. I have a 1993 civic hatchback si - b18b1 swap - DC sports 4-2-1 header and Yonaka High flow catalytic converter.

I bolted it together, put it on my hangars and that was that. My cousin welded flanges to the cat and bolted the cat in place. Very satisfied with the exhaust, especially for the price. The only part I didn't like is how big the muffler/tip is but its slowly growing on me and i'll deal with it considering the great price/sound. I'm a strong believer in a cat helping reduce/eliminate rasp..

EDIT: I am lowered on Yonaka Coilovers as well, front are adjusted all the way down except in last picure they were not quite all the way down yet


Unboxed:
















I plan on buying muflaps for the car. It should help hide the muffler more from the side and tidy things up















Good shot of resonator and muffler clearance:

Bumping an old thread. Fast forward a couple of years.... how has this catback been holding up for everyone ?
