Looking for either brand or part number for Lt headers and mid pipe that will fit 2004 Gt with an Automatic trans, Currently I have Magnaflow X pipe and cat back I know I will have to replace the x pipe but would like to keep the cat back any suggestions

 

SLP or Bassani.

 

what he said...either brand is extremely nice but theyre pricy...SLP offers longtubes and you can only use their x pipe cause its not a flange type connection.its a clamp that holds them together

bassani makes midlength headers..a mix between LT's and shorties...and you can only use their x-pipe cause theyre the only ones that make midpipes to fit mid length headers

 

There's not too many that fit auto's. I do not believe BBK does, and not sure about MAC. If Mac does, then they're going to be your cheapest LT's, but I'm not sure what midpipe would fit.

I have full SLP setup with SLP LT's, SLP Catted X-pipe, and SLP LMII on my auto. I personally love it if you can afford it. I paid $900 for my LT's and SLP Catted X-pipe brand new. I got a deal because I got a local performance shop to become an authorized dealer for SLP and he saved me about $200. Installation was $600 for the Lt's and Xpipe. They lifted the motor to be able to fit them, took them 2 days since it was his 1st modular motor install. Also I used the supplied gaskets and haven't ever had any leaking issues. It's been about 14 months since install. Total cost was about $1500. LT's isn't the greatest source of horsepower increase, but it is pretty good. I think LT's is more for an exhaust sounding personalization. There is a link to a short vid of my exhaust set up. I hope this helps you.

Mac WILL fit and so will Hooker. You can actually drop the auto tranny with the Hookers still on. With the Mac's, you have to remove the pass. side header.

I run Mac LT's.
