Well, the title sums it up. Give me all your knowledge on the subject taking into consideration performance and sound and how it'll work with my MAC cat back.....
I look forward to all your opinions!!

 

I say X/H with cats but thats just me.

 

X with cats if it were me.

 

why the X not the H? just curious

 

i say either one but not the prochamber heard their not good

 

the X is just a matter of opininon for me, that's what i'm usin now. i had a 3in pro chamber on a 91 gt with 1 3/4 LT's and a 3in cat back with tfs stage 3 heads. that thing was loud as hell.

 

Cats or no cats? depends on where you live. Emissions or not? Here in FL no emissions = no cats.

X or H? That is personal preference. I originally had an H pipe with dynomax mufflers. Changed to an X pipe because I was told more HP and TQ. However the sound changed. My car was a little quieter and less of a growl. Changed back to an H pipe (no reason other than sound).

Also I want to get a Flowmaster cat back exhaust because of their distinct mustang sound. When I do I'm thinking 2 chambers with and X pipe or 3 chambers with an H pipe. But most likely I'll go 2 chambers and the H to be as loud as I can!

I haven't heard to much about MAC prochambers recently. Heard it was supposed to give more HP and TQ than standard H pipe, but I think more people are buying H and X's because of the price.

 

Yep..a friend in trying to convince me to buy a pro chamber but the price is really steep..especially with cats!! My big desicion is to cat or not..can i be bothered swapping and changing all the time?? They are a bit more expensive but don't really rob power and are legal.

 

in my opinion you're better off running cats, that way you're legal and don't have to swap.

 

I was told that if you wanted bottom end torque that you would want to go with the h pipe and if you wanted to go with top end power you would go with the x pipe. I have equal length headers, 2.5 inch h pipe with cats flowmaster 1 chambers and 2.5 inch tail pipes, and sounds very aggressive and have been complemented by many people on the streets.
