Is that 3" pipe?
Will it mate up to shorty el headers too?
(Cause if not gonna have to reconsider long tubes)

As of now the system will not mate to a standard flange system but that can be done fairly easily with 2 Norma connection extensions.

This is a 2-1-2 dumping into a single cat at 3.5" Like I said though still a bit of tuning and further fabrication. Currently we are using the previous axle back that we fabricated out of 3" to dual 2.5" and we will be stepping up the diameter and doing some acoustic tuning in the midpipe, then converting to several different materials, currently steel for proto.

Seriously swapping .
Thx!

Spring restriction that limits loudness at low flow low power and opens up full diameter at high flow high power with no noise restriction.
90 or 115mm tip inserts.(kind of a poor mans dual mode)

Dropped my car off with Paul @ PPE this morning for the header/exhaust install. They're going to be doing some dynos in-between installations then i'll have it back Friday. I'll post up some exhaust sounds this weekend for that combination.

^^^Awesome! Can't wait to see the before and after dyno runs with these equal length shorties!
#55
Also very interested in how this sounds! I have a PPE dual and having been looking to add headers but with these new developments very curious to see how the EL changes the sound.

Update on dyno numbers and exhaust sounds por favor
#57
Paul was sick two days last week so they haven't finished. I'll get it back this week then post them up. The baselines were done in 4th and 5th, but the next will be 5th (for comparison) and 6th. Suspense is killing me too.

Thanks for the update

Got the car back yesterday and i'll post up some videos later today or tomorrow. I tried taking some videos yesterday, but it was pretty windy and you can hear it so i'll have to take new ones.
Dynos are extremely confusing to me and i've got an email out to Paul to see if he can provide some information. I have the base line dynos then dynos for after headers/exhaust. It only gained 34-37whp from both headers and exhaust so i'm not sure how that could be. Temperature was the same in both dynos at a cool 103 degrees. Looking at Lou's prior dynos it looks like he gained about 18whp from the exhaust alone. Equal length headers appear to be gaining about same as unequal length at peak from his unequal/equal length dynos.
I'll post up the dynos later as well with the sound clips.
EDIT: I just noticed the temperatures when Lou ran his Dynos which were 70-80 degrees.

Awesome! Looking forward to them, sounds like other than the sound difference between the Unequal & Equal length headers that the power gained is about the same.....
