2015-2020 Mustang GT Cat Delete Pipes: First To Market and The Original Cat Deletes

[AdrianMAK]

I haven't even gotten my deletes yet, but have already ordered two resonators to go back in since already removed factory suitcase. Should knock down the extra loudness no prob. $100 for two stainless bullet resonators.

Yes that should effeminately bring the volume down.

Back In STOCK and ready to ship!

Installed my mak cat deletes, pmas cai, and tune revision for cai. Put it back on the dyno and only gained 14 rwhp peak and 1 rwtq peak from dyno last week.
Across the dyno at the top there are a few places where i gain approx 30 rwtq.
I know there is a debate about loss of back pressure causing you to lose low end torque, but in my opinion i just moved my power band up. Man let me tell you after 4000 rpm she pulls like a mule.
Will data log after i purchase a laptop to see if lund can adjust anything.
Even with the small increase still very happy with the tune and parts.
The Mak cat deletes, heartthrob h-pipe and pypes muffler deletes sound awesome

I wonder if it's the CAI, I gained a ton with the deletes through my whole power band. I do t have a CAI.

Dyno sheet.

1st run stock, 391rwhp baseline pull.
2nd run stock plus tune, +9rwhp over stock tune alone. :(
3rd run tune plus exhaust, +20rwhp over tune, but +29rwhp over stock!!!

Same day runs. :cheers:

I gained 16 hp from just the cat deletes.

That I don't know. The only thing i have noticed with the cai is that the ait temps get really high, but drop back down. Not really worried about that.

The car definitely feels stronger just gets stronger after 4000 rpm. Will try and post my dyno sheets later. I ran a data log last night and am getting -timing which is good through all gears

Peak?

There is a big section of dyno that gives me 20-35 rwtq throughout the power band after 4200 rpm'

 

[Soonertim4]

My logs from last week and yesterday interweave together until after 4200 rpms then it is a solid gain. I am pretty sure it is just a tune adjustment away from being fixed. Jus need to purchase a laptop

That CAI he has has independent dyno proven 14-17whp gains on its own.

That's crazy! I kind of understand that to mean he net zero hp from the deletes. I am really interested in that PMAS intake too. Looks ugly as crap but functional as whoa.

I mean, just look at my torque gains from 2900 - 3400. Freaking beast man. No idea why he wouldn't gain anything.

Mine on the same dyno ( different day but close to the same DA ) Picked up zero HP or TQ ..Infact I lost 4 HP at peak and 2 foot pounds of TQ ..I didn't change mine looking for more HP , I changed them because I was burning up my Cats ..

 

[Soonertim4]

Question. Is there a possiblity that when they uploaded the tune revision to my ngauge that they reloaded the first tune instead of the revision tune?
The tune revision was for cai only. I got in my car tonight and dove for aboot 10 mins and was jus sluggish on low end. Pulled over went through tunes and loaded revision and drove around.
Right now is half ass raining in north houston so i couldnt get on it, but it seemed a little snappier down low :shrug:
Also my spark advance was around 29 last night and tonight slower driving is was around 35-37
Just wonderin
Still gonna get laptop and send data log to John at Lund (btw sent him en email earlier after their hours and he replied within 5 min)

I did gain good torque throughout the curve just not peak or down low
