stack question
 

gonna get a single stack. the stacks that are 6-8 inchs with the five inch I.D. does the stack just go into the five inch 90 degree elbow

I think its all going to depend if your 90 is flared to fit the 5" or if its strait then you need the 5id/5od connector. I'd try to fit your stack and the elbow off the truck just to be sure. :tu:
