exhaust
 

I am planning on getting dual exhaust on my car (95'). I want to get 2 chamber flowmasters but i dont know whether to get an H-Pipe or run straight pipes from the cats back to increase air flow. Which would have a deaper sound and add more hp. Also would it be worth it to have 2 cats removed?

I have done a ton of research on this. If you like the sound of an outboard boat motor go with stright pipes. If you like the sounds of the Cobra's go with the MAC off-road h-pipe. If you are going to duals get rid of all 4 cats. If you go any bigger than 2.5" pipes YOU WILL LOSE HORSEPOWER. If you stick with 2.5" 2-chamber flows it will sound darn good and gain alot of power. I put the MAC off-road h-pipe on with two 2-chamber flows and everyone thinks it is an eight it took me about 2 hrs to put it all on. Good luck and if you have anymore questions please ask.

If i get the MAC H-Pipe and get rid of all the cats does the h-pipe run all the way to the headers. Will i lose hp if i go with 2 1/2 pipes and 3' tips? Does the sound have a good low rumble?

MAC h-pipe does run all the way to the headers. You will not lose hp with 3.5 tips and most likly will not change the sould that much. It is more or less your choice in style. Also Check with your local laws and make sure you can get away with not having CATS. If you get emission checks than you may not be able to them on.
