What brand cats are these?

Way more room with the kooks 1 7/8

Be prepared for how loud it will be! After one week off driving with the Kooks LTH's I bought the green cats to bring the noise down and get rid of smell. And this is with MMF street series exhaust, I think there lowest noise level exhaust.

I've failed 2 sets of factory cats in 5,000 miles. If these green cats live to the end of there 2 year warranty it's a win, so much easier to change out now. I have a new set of factory cats if anyone is interested.

It states on the the kooks website, kooks high flow cats are NOT meant for boost, only green cats which are furnace brazed.

So Roush will provide the tune but will no longer cover the install since out of warranty now, not a big deal but sucks since its been almost 4 years to get the tune kinda right!

Does anyone know the date of the latest tune revision for 2018 Gt with Roush stage 2? My last revision was on 4/26/21, P1318-P2-AA, which seems pretty good for about the 6th flash I think, lol

Did you have to adjust the tune to run a BAP? Or just Roush tune?

I remember my first time too, 1984 SVO around 1990, made 261hp at the tires , LMAO I've been kicking around having a "aftermarket tune" on my 18 since the Roush warranty is gone now, just not sure if it's worth $1200 for tune and devise. This last revision form Roush has been pretty good, but it...

2018 Gt auto, dealer installed Roush stage 2 blower kit, catback exhaust, whipple OS HE, that's it

Do you need a copy of the Roush tune? I'm probably on the 10th revision, lol

yes

Daryle, Would I need to flash back to stock if using your tune with a RTD tuner? 18 roush stage 2

Spoke to Gavin just now, new revision for phase 2 will not be available till mid October now, oh well!

This is MY pic from page 16. Get your facts right. Stage 2 Roush on left, whipple oversize on right.

Went to Barcelona, Sitges and Mallorca last year, looking back, we wished we had spent the whole trip on the island of Mallorca. And the beach, most of the women are topless, just a natural thing over there,lol

Here you go, pick your poison for 40K https://www.lebanonfordperformance.com/2019-ford-mustang-pick-your-power-for-39995-2/

Sorry if this is a little off topic but, I run 2 gal of E85 and the rest 93 octane every fill up and have had no issues, should be around 95 octane. Terry at Beefcake has mentioned same thing. E85 is everywhere by me though.

Damn, I'd be there for sure, but early flight to vegas in the morning. Drove the car to work today, just a damn animal in these cool temps, I absolutely have no regrets getting the Roush system, love it! AS good as it's running now, I doubt if I'll even get a after market tune when warranty is...

Not that hard, just time consuming taking off front fascia, would have been easier with 2 people putting it back on.
