Alright guys I currently have stock headers, an offroad midpipe and a catback. Now I want to go with some longtube headers, do I have to replace the midpipe? I'm not sure but I think they make different midpipes for shorty and longtube headers. Let me know..

Yes. It also helps to stay with the same brand.

Yup you got to dude.

il 3rd those statements, you need a shorter one specificaly for long tubes

yup !!!:D

when I converted to long tubes, I bought the midpipe that was "supposed" to match it...

I ended up going back to my BBK X-pipe... I just had to... Adder-ize it...
