I took this video today after getting the vacuum leak fixed, rear o2s, n x pipe installed. Still have not finished both tailpipes
Once I get the exhaust all done I’ll get a better video n rev it up

Some before n after pics of the engine n exhaust. Still need to finish up the rest of the exhaust
Also got an x brace off an sn95 convertible from offerup for $20 it fit good just had to modify the front part of it to have it properly bolted on
Found a supercharger kit Im going save up for I doubt it’ll fit under the hood n strut brace with that though but it’d be badass in there

Got the exhaust all done today I got it tucked up tight so hopefully it won’t get dinged up anymore
I got the lightning style tips on I think they look pretty good they’re also dual walled so they don’t get too hot to touch
Need to finish the suspension/brakes then I can take it for a drive

The 2v elbow shouldn’t be much of a restriction the mustang throttle body is 70mm I believe the 5.4 3v throttle body is 75mm. I’ve ordered a 75mm throttle body should be here soon also had to find some 21lb/hr ev14 injectors since the only ones I had laying around are 24lb/hr n fuel trims are showing a bit rich. The correct size injectors should be here soon
I won’t be getting it on a dyno anytime soon I’m looking into supercharger kits first then after that will definitely get it tuned for now it’ll just run on the stock tune
I got started on the rear suspension today installed the bmr upper torque box reinforcement kit, spherical bushings on the diff, n doing poly bushings on the stock arms, stock shocks will stay for now the car only has 40k miles so I think they’re fine n it has steeda lowering springs already so I’ll just be painting those red. Still waiting on some parts for the front end n have to replace diff seals n finish brakes as well
Also got a better clip of the exhaust at idle

Comming along nicely . That 75mm tb will be a good bump in power

Got the suspension assembled, sealed up the diff, n replaced the drive shaft u joints. Also got a Honda power steering reservoir with bracket installed in place of the battery tray. Swapped out the front brakes but they fit a bit tight inside the 18s I’m looking at getting some 19s of a 2015 Gt. Installed the cobra front bumper still need to get a chin spoiler for it.

Got the correct size injectors on it, got the throttle body on it, installed new shocks n struts, bled the brakes, hooked up the amp power wire to a battery in the trunk for now n took it for a drive
Pulls great but fuel trims lean out in higher rpm’s definitely could benefit from a tune might look into that any suggestions would be great. But it pulls nice as is
So far no dtcs so if all is good after a few more miles I’ll take it through emissions testing then get it registered. Still need new tires not sure if I should keep the gt500 rims or not still looking for 18” roush wheels but not much luck
I’m not digging the cobra bumper might end up getting the cobra r bumper instead seems like that one hangs lower would match the side skirts a bit better
