Installed True Dual Exhaust on my 01 XL

[06JET]

Had some fun this weekend installing dual exhaust with 24" Cherry Bombs. Not loud but has some sound when under load. Goes well with the big ride.

You gotta get us video!

No H or X pipe?

No X or H. I wanted them separate all the way out. I'll try to get a video later. I still need to fix an exhaust manifold leak from a broken bolt. I have the repair bolt/clamp part but it still leaks at the first start when it is cold then goes away when it warms up.

Do you feel like you lost some low end torque?

Why would you think he would lose low end torque?

i have a terrible memory so ill try to go with the basics so i dont provide poor information. exhaust flow can have an impact on the power curve so if op went dual exhaust as shown it can lower the power one spot but increase the power elsewhere. i cant remember the specifics but it definitely wouldn't be the first time i was asked why someones car feels like it got slower off the line after a diy custom exhaust. usually when someone went too big on pipe diameter for a dual exhaust system for an engine that doesn't have the velocity to do it. op doesn't look like they went overkill and kept with the original pipe size coming off the front so it wouldn't be the case here. so @Javie was probably just asking for reference purposes im assuming. im no exhaust guru so i generally just have an exhaust shop do a system for me or i buy a kit so i know it works with the vehicle fit and function.

It's been proven having a h or x pipe helps with scavenging, which results in more power.

Because of the infamous myth on loss of back pressure.

I used to have an 05 Tahoe with the LM7 5.3. I had true duals put on using 2.5" pipe, it didn't lose any low end torque at all.

Did it sound bad ass?
