Power (Up/Down)grade going from TDs to cutout?
Power (Up/Down)grade going from TDs to cutout? Alright fellas, ripping the exhaust out of my car for clearance reasons primarily, and room to grow reasons secondarily.
Currently has a fantastic set of LPP 1 3/4inch stainless headers on it. goes into a 3inch TSP true dual system that dumps at the axle.
Switching to a TSP 1 7/8 inch header running to a 3inch electric cutout and a magnaflow catback.
Am I going to be losing power, gaining power, or staying the same (on this stock cubed 6 liter).
Car made 398 rwhp, 395 rwtq in its current form. In the end, it's probably only going to be a marginal +/- difference in horsepower, but I'm curious as I will be riding around on this setup for a year or so until the build comes together.

Verdad Gallardo I don't really plan on dynoing the car. Probably a waste of money at that point. It's tuned as it is now, and it probably doesn't need a re-tune, and that would be the only time I would put it on the dyno. Just knowing that in theory, I should be making a few more ponies is good enough for me.
The catback is not the point of this, I'm running a cutout.
And in my first post, I said ground clearance was the largest issue.

your going from 3" duals with bullets to a 3" y pipe to ONE 3" cut out. the 3" bullets dont hold back anything. i understand the 1 7/8 headers give you room to grow but the y pipe is going to hold you back anything over 500hp even with the cutout open. At your current power level the 1 7/8 headers, y pipe, cutout i think you will lose a little hp.
what you need to do is a setup like mine. it costs but worth it. I have american racing 1 7/8 headers and there 3" y pipe that goes to a magnaflow catback with an extra mufler in the i-pipe to control sound when crusin. But what i did was put 2 low profile oval cutouts from DHM in my y-pipe right after the first bends. IMO this is the best street/strip setup.

Well, for what it's worth, I'm doing dual DMH electric cutouts, probably going to hack up the ORY a bit and put them just before the bend into the merge.
Thanks for letting me know guys.
