Yes Colin, I do confirm having strong droning with my setup.
L.L., thank you for your last post.
I think I will soon move to the Lithfield system. I'll keep you inform here about my feeling when installed.
Once again thanks everybody for advises,
Thom

Adding a single Borla muffler to my midpipe on a completely cat-free system got rid of 100% of the raspy (i.e. crappy pickup truck) sounds and killed any cruising drone.  Still sounds great at WOT though.  I'm guessing you might have some difficulty finding a fabricator that is able to modify a Ti system, but if you can it could be cheaper/easier than completely replacing the whole system.

 

I did this on my previous GT-R and agree 100%. Made a huge difference!

I debated whether to start a new thread but since the dyno session was for the sole purpose of comparing the numbers of the Litchfield system vs the OEM catback, I'll just post here so others will know what to expect in the future.

 

Copy and pasted from the thread on the other forum:

 

 

 

The dyno session at ACG Automotive was yesterday afternoon and Chris Black was able to clean things up with three pulls. We confirmed what usually happens going to a larger exhaust without a revised tune during the initial baseline run. The car gained 32HP up top and lost some low end torque. Looking at our street logs from last week, we knew that was going to occur due to increased boost on the top end under heavier loads in 3rd to 4th gear. The HP gain might not be considered a direct result of the exhaust; more so the boost increase due to a freer flowing exhaust. Would be interested to hear thoughts on this.
 
Because the car is still running a stock transmission, we elected to keep things conservative as the clutch was starting to slip with the bump in power. Chris kept me at +10HP over my original tune numbers with a similar torque number (648/555 on a Mustang dyno). We also added the Cobb TCM add-on to adjust clutch capacity and added two more maps (low and medium in addition to kill).
 
I'm pretty happy with the numbers and the car runs great so, unless something unforeseen occurs (knock on wood), the car will remain in its current state for a little while until I'm ready for a Shep transmission. Thanks to James and Scott at ACG along with Chris Black for the continued support in getting the car running perfectly!
 
Here's the video and some photos from yesterday:

Thank you L.L., that's interesting.
The sound level during this dyno session seems really decent, and very nice at full throttle.

I received my exhaust but won't be able to put it into the car until next week...can't wait to do it but too much work!!!

My goal is 1200whp street car that's smooth and civilized. Not cheap to do, but its worth it to me, we just spent 3 weeks on redoing entire interior with sound deadener and alcantara. Titan street and rsonated ypipe should be very good.

I also did the sound deadening a few months ago. It was a ton of work but worth it in end. 3-4db reduction in road noise at highway speeds. Please share your thoughts on what you think of the car after the new midpipe and sound deadener. Would also be interested in hearing the exhaust with new ypipe.
