Here's two clips of my car. First video is in 3rd gear, and the second video is in 4th gear. Ignore the break squealing in the first video...

It sounds normal to me. These cars like to trumpet, I dont think theres really a way around it unless you have factory cats.

I'll probably try a new axle back down the road, but right now it's not hurting performance, so I'd rather throw money at go fast parts lol

Got the super 10s in and it sounds meaty. Super deep idle and 99% of the trumpeting is gone.

I went through a couple exhausts and returned them to amazon for a full refund. The gt500 axle backs went back in. The outlaws were too raspy and blatty sounding. The stingers were raspy too, and I could never get the tips to stay lined up.

View attachment 69372

I have the identical setup JBA's ( titanium ceramic coated ) JBA H pipe... and a pair of welded in M80's. At the time, the M80's from AM were $44.00 each. Flanges on each end of the M80's cut off in band saw.... then they were welded in.... just b4 the rear axle.

No need to burn the car. But they need to heat cycle several times .....so fully evaluate em after 2-3-4 weeks. After that, they won't change.

Also bought new oem Ford header gaskets. Came as a pair, also from AM...dirt cheap at the time. FRPP gaskets. Don't re-use the old crap. LT's are a tedious enough install. Check TQ on header bolts after a month..then 1-2 per year after.
