I have a 2001, with a mac catback, and am thinking about getting a set of JBA shirty headers.
My question is do the headers just bolt onto my existing setup, or do I have to weld them on?

 

they bolt on, but shortyys are a waste of money get LT

 

I agree shorty headers are a waste and you already have some now that are good up to 300 hp. I wouldn't go with long tubes unless you plan on racing a lot. For one they won't pass smog and you'll lose a lot of low end power. Also with no other engine mods headers are a waste of money.

 

get lt's or go home

 

Unless you want a turbo, then LT's will be a waist.

 

the v6 has headers from the factory so shorty headers don't do anything. to answer your question they just bolt on.

 

wtf? you mean if you want a turbo lts will be a waist. if he gets a turbo lts wont fit on his car, if he doesnt want a turbo then lts might give him a few ponies

 

Well seeing as I actually have longtubes let me chime in, lt's are great for an overall power gain but, you WILL lose power down low, but it pays off I believe that the longtubes changed my entire powerband, I also feel like I have much more top end pull!

 

I just said the same thing, the only difference is that I added a comma and "then", you know, to like be all props wit muh grammah what shiz.

 

no he repeted u sayin wtf are u talkin about???
listen to flash who has him and +1 to what he said about them
