2019 GT - SP Longtubes, Lund E85R tune (on tested E85), stock intake/manifold, catback exhaust, 6spd

It has a catback exhaust, forget which, but its loud as hell. Basically the longtubes and a loud exhaust, no OEM pipes. Most of the power is coming from the E85, the longtubes added about 17whp and 20wtq.

Are these LTHs 1 7/8s or 13/4s? I’ve read somewhere to go 1 3/4s if staying NA. Is this right?

The fastest NA cars are running 1 7/8. 500+ whp & 8000 RPM. I would. JMO

There’s a guy in the fastest list running 10s with tune and intake.

Op has the best setup for the money imo. Everything else adds a couple hp here and there. Porting a intake manifold isn’t worth 5hp to me. Shit cat deletes dyno the same as ltbs
