Our muffler was damaged by a shop tech (Not real bad, but the owner said we'll make it right.) His costs for a replacement muffler was credited towards what I purchased was an Aero 5050XL, which the shop did a great job of installing.
I went with the Aero because a friend with an ISL in SOB, said he saw a bit faster spooling of the turbo. I fell I do too, especially in 3rd and 4th gear merging situations. (Both ISL's, were CAPS era, without Variable Geometry Turbo. I mention this, because I believe the Common Rail with VGT era ISL's - Turbo would behave differently the our era. Could be even better, as the VGT is capable of higher PSI then our era Turbo.).
A bit louder, but not noticeable going down the highway, and if I just idle out of a park - not much different then OEM. MPG might be a tad better too, but sure was not a reason to have added the unit. I was hoping the advertised lower back pressure of the Aero - would yield a bit faster spooling as my friend saw - and I feel it does, so am happy with it. It's also stainless steel, and hoping it will last a long time...
I will share that the OEM on our 04 Allure, was a good good size muffler, so not near as restrictive as I've seen on some other manufactures:)!
Best to all,
