Hey guys i have an o/r mac H pipe on my car, and i was wondering if i could get longtubes or would i have to get shorties? I have an auto too

 

well your mid pipe will not work with long tubes but you should just get a shorty mid pipe and long tubes. don't get the shorty headers

 

I have an auto too and was told that you need to modify ( grind ) the long tubes somewhere to me'em fit properly, i think it was the passanger side. If you get em let me know how it goes as this is on my list to do

 

There's a mid pipe for shorties and one for LT's

 

Depending on what brand of longtubes their is no fitment issue with auto tranny. I know mac fits it.
You can not reuse the hpipe on longtubes and shorties arnt worth the money they cost.

 

MAC should fit with no modifications to them.

 

yea i am an auto to man and Mac LT's fit fine with no probs
