I run Valvoline European 5W-40. Good oil and fair price at Walmart. I ran Motorcraft synthetic 5W-50 for couple oil changes but read it shears to 5W-40 rather quickly and it more expensive.
it’s not.. info on their site is misleading… rear connection is 3” but the front is made to connect to factory size something like 2.25”… I cut off the 2.25” section and was left with a 2.5” stub that I had the 2.5”-3” adapters welded onto…internally it’s 2.5”
just an fyi the Borla resonator is quiet for about the first week. once it sees some wot runs it seems to loose its muffling ability...on cold start mine is still loud, better than the x pipe but only by a small margin
Driven both the MT and Nitto on the street and 1/4 mile.. both are good but most important to me is the Nittos balance better and run truer… much better ride over MT… had my best 60’ with the Nitto 1.57 stock converter A10.
I’m my opinion if the dyno isn’t happy and those power numbers are legit you are looking for trouble on 93 octane with additive and meth… who is tuning the car?
Sportsman S/R are ok on the street if you don’t drive like or are not an “idiot”. So speak for yourself ZXMustang. They have a very stiff sidewall and great load handling capability.
I wouldn’t drive and ET Front on the street.
You boys need to learn your limitations.
