About to do the install this weekend hopefully, and I was wondering if there will need to be any cutting of the I pipe to make room for the Y pipe?? I thought I heard that somewhere but wanted to make sure. Its just something I have been wondering about lately. Wanna have a good idea as to everything I can before going into it to limit the surprises along the way if ya know what I mean.

 

On my car and my buddies TA we had to cut about 4"-6" off of the I pipe.
