Ya know, I absolutely HATED the way magnaflows sounded on my crown Vic. I swapped them out for borla stingers and never looked back. Honestly though, after watching the video you posted, I really really wish I had bought the magnaflow. I love the tone you got with your magnaflow. I even used studio headphones and beats audio to listen to it lol

However, I work less hours, Have less stress, No customers, Free Medical and Dental, and Weekends off, With paid Holidays. And I am Building a YJ at the same time as the XJ so can you say Gonna go Bankrupt lol

The APN is made out of really heavy gauge steel, idk about banks. APN cost $10 more than an OEM replacement though so I'd go with that.
Spintech 9000s have a smooth tone too btw, and they're very compact.[/QUOTE]
The Banks Revolver is made of 409 mandrel bent stainless stell tubing

APN is a clone of the banks torquetube header which was repalced by the revolver

Ok, so I just put a Flowmaster 44 on my XJ. I like the sound it makes, but I am wondering if there was a better choice for relatively the same price, I got all the parts I needed at $110.

Looking to do my exhaust from headers back sometime soon, along with 4 new o2 sensors.
I have a 2001 cherokee so I have the two piece headers and pre cats.
Does anyone know any good routes to take?
Also I read somewhere that I should get the 02 sensors from the dealer because the xj's are picky with them? or are bosch fine?

Yesterday I had to take my cat off because it was rusted beyond belief and falling off...right now it is an open exhaust on my 99 jeep xj 4.0l....it sounds real nice but not practical unfortunately....Can anyone tell me if everything exhaust wise is 2.25 on the xj? If i were to get one of the performance curve hi flow cats would i be fine getting the 2.25 universal...i plan to run the cat back to a glass pack and then do a side dump or something like that...any help would be appreciated thanks.

Read my build thread and a few post up I have a YouTube clip of my Xj's exhaust ( 2.5" manifold back exhaust with a 2.5" high flow cat and magnaflow magnapack muffler with a 2.5" tailpipe ) I got everything from performance curve minus the custom down pipe. I had a local shop bend up when the welding everything up. On Tuesday I will be getting my header then getting it ceramic coated. Hopefully I will install in within the next couple of weeks and making a few more videos.
