i have hooker long tubes and i just bought a y pipe so i could put single exhaust back on my car. its made by .
stainless works. im having a hard time installing it, it doesent seem to line up right. does anyone use this y pipe did you have any probs with it

 

The pre-fabricated y-pipes for long tube headers usually don't fit that well, I'd just take it to an exhaust shop and have them make the necessary modifications to get it to fit.
