Sounds good with the 4.0. Not too loud but definitely more growly.

great sounding muffler on my 97 jeep zj 5.2. shipping was a day late (purolator mishap). may need to get an adapter for the tailpipe to fit correctly as I just loose fit it to the cat, I will update soon as I compete instal

Muy buen artículo

Es un producto de buena calidad, bien hecho. Aún no se ha instalado así que en cuanto a funcionamiento no lo puedo calificar todavía. El tamaño que viene anunciado en la publicación (51x25x11.2cm) no es el correcto, esas son las dimensiones del paquete, las dimensiones del mofle son 34 (tamaño total del silenciador)x25x11.2cm. Sumando a los 34 la longitud de la entrada y la salida dan 50. Sería mucho mas sencillo si se publicara un boceto con las dimensiones del producto.

I love this muffler put it on my 2001 jeep grand cherokee 4.0 and the sound is amazing I have also noticed a performance increase feels like the jeep has more power and the ride is smoother my muffler was preety rusted out before and was stock. I love the bubbly throaty sound this thing gives at idle its quiet but you can still notice its there. It is not as agressive and loud as i thought but its loud when you need it to be and more quiet at lower rpms. If you love sound but want a more smooth and quiet engine rev but yet it still roars when you need it to. This muffler is for you.
