I got a 94 integra ls, and im looking at a good deal on a gsr header and cat. will that bolt up to a stock 94 integra cat-back? I searched and cant find much about that

 

There are two different part number from Acura, so I would guess that there is a length issue with the midpipe. Here is the GSR number: 18220-ST7-A63 and LS number: 18220-ST7-A43. If you have a sawzall, and/or exhaust pipe cutter, and welder I am sure you can make it work though. Good luck!

 

yea thats what i saw too. i dont have a welder sooo i might just have an exhaust shop do it. thanks

 

If it is the stock header and cat it won't do you any good anyway.

 

if your getting a good deal i would buy it and cut if i needed too

 

If the its the stock GSR header, than its going to be too short i think. I remember someone telling me that

 

only the 00-01 gsr header will bolt up to the ls exhaust due to the length. the 94-99 will not.

 

What he said ^

 

your right i had the same problem on my ls/vtec da, it was about 5 inches too short so what i did was i was building a strait pipe for it so i took the cat off ( no emmisions anymore on 95 and older here) and welded a flange i cut from the stock converter and welded it to some 2 1/2 piping and connected it to my exhaust. you can do the same exept you will need to cut the flange on the cat and make a 5'' piece and just buzz in a pipe between them

 

oh yeah if u dont have aftermarket motor mounts u need a flex pipe or the spring bolts from the cat moved to the back buy a third one, i know its ghetto but if u dont want to buy a flex pipe u gotta do what u gotta do

 

the cat lengths are different between itr, gsr and ls. Also the flanges are clocked to different positions.
