I would think you could get at it at an angle?

Nice! I can’t wait! I might have to try and put it on the frame machine at work to avoid dropping the whole exhaust

I picked up a little torque gain below the curve from about 2000 - 3800 rpm. Steeda H-pipe with active exhaust sounds amazing.

Interesting that the HP actually dipped down a smidge. Could it have just been the increase in DA that caused it?

That would be my guess. DA was higher on the afternoon pulls not to mention the fact that I'd just driven about an hour with the A/C running at 80-85 mph. Car was definitely a little more heat soaked as well.

Just installed my steeda h-pipe! Deeper rumble at idle and man when you get on it, it sounds bad ass! Has anyone installed a catback or longtubes with the h-pipe?

I have active exhaust with H pipe and just installed mak cat deletes Monday. Ive only driven it once since I installed them. Much louder. I do not mind the loudness since its not a DD and in quite and normal it is still pretty quite and tame cruising. I just dont know how much I like the sound

Yeah I'd like to make mine a little louder as well but the axle backs for these cars are expensive...

The mak cat deletes, are they the same company as mac performance? I loved my mac prochamber and flows on my 03 cobra, just new to the coyote motor and haven't heard enough of them in person to know what sounds good?

I had the shop chop mine down to fit the rest of the system.

$70 (+labor, so $300) solution (instead of 1000-1600) to the heat-soaking of the differential problem.
