Here is my combo:
92' LX
331 w/ tfs heads (9:1)
TFS stage 1 cam (1.7 rr's)
gt-40 intake w/65mm tb
s-trim (6lbs)
SCT MAF
UPR Power Pipe
SCT custom tune
mac unequal length headers
bassani OR x-pipe
mac cat back
I want to swap my Bassani OR X pipe with a catt'd Mac H-pipe to try and quiet the car down a bit.
How much power do you think I will loose by doing this?
You know Long tubes will quiet the car down as well. In any case I would guess 10-20 rwhp.
You could always put a little more boost to it and make up for any power loss.
Also maybe try some magnaflow mufflers. Very smooth idle with cats.

Well, I put my mac h-pipe with cats back on and the car is definitely quieter. No more raspy scream. I haven't really gotten on the car yet as I installed a power pipe and need to go for a re-tune on Tuesday. I will post of before and after power numbers. Although It won't be an apples to apples compare as my 1st tune was done on a dynojet and this one will be a Mustang dyno.
I plan on changing my exhaust setup when I install my panhard bar. I think I will go with the dynomax setup as I still want to have tail pipes out the back. What do you think of the dynomax with the bassani x-pipe? Will it be quieter than the bassani/mac combo? I'm not looking to go too quiet. I just don't want inocent bystandards to stare in terror as I roll through their neighborhood :DQuote:
