My setup I want to build is long tube headers, to high flow cats with me able to take them out and have no cats to H pipe then mufflers then to the side of the car in front of the rear tires. Does that sound like a good combo?? i need to find some good mufflers that will be somewhat like the cervinnis kit mufflers the long and skinny ones. Where can I get the h pipe i cant seem to find one for a v6??

 

I'm pretty sure the stock GT H-Pipe will bolt up.

 

If you have a 2005-2009 your 2 1/4 will fit inside the 2 1/2 h pipe and will have to use a horseshoe clamp, 2010+ regular clamps will join the two together.

 

I'm trying to get a deep sound more than worry about hp or tq I'm thinking slp loudmouth mufflers

 

Everyone I know who pulled the cats off a 4.0 has been unhappy with the sound -- just an FYI

 

Well I'm not to worried since my cats are hollow right now.
