Just put a si/so magnaflow on my truck i didnt want anything loud just a little rumble. I love it it sounds great very mellow can hardly hear it in the cab with windows up. Just thought id share

 

Same thing here. I just put the SI/SO Magnaflow on my 04 with the 5.4. I had a similar SI/SO Flowmaster setup on my last truck, a Chevy 2500HD with the 6.0 but I didn't want this truck quite that loud this time. I went with my muffler guy's recommendation and did the magnaflow. Very happy with the results.

 

Excellent!

 

Magnaflow is always a good good choice

 

Also did the gotts mod today just finished it havent test drove but it went together well and looks good.

 

i swear my truck would fall on it's face every time i took off. 1st...bog 2nd...bog 3rd...bog
couse of the gearing. any way, i did the gotts mod and it seemed to "wake up" the responsivness and it don't bog any more. she runs good now
