I know there's a lot of reviews for this exhaust but I just wanted to put in my 2 cents. I just installed the exhaust last night, it only took 3 hours and all I had was 2 jack stands to help me get under it. It's a really easy install taking off the rusty stock exhaust was the hard part. The exhaust sounds grrrr8 and the j pipes work real well. I took it on I-20 and let AFM kick in and it was still quiet inside even though a lot of review said it would not get rid of it, it did for me would definently recommend this exhaust.
