Im about to order a set of the stainless works headers with cats for my 2010 5.4. Just wanted to know which mufflers would sound good without being too loud. I will be running turndowns on the mufflers because of my lowering kit. I dont mind it being loud at highway speeds but around town it can get annoying. Also, leaning towards borla from good past experiences but I'm open to any suggestions. Thanks.

 

The largest size Borla ProXS. I believe there is a 24" length body. Or a 21", not very sure.

 

Longest ones listed on their site are 19".

 

Well thats correct, I can't find anything greater than he 19" body until stepping into the Turbo XL line of mufflers. The 19" body should keep things subtle enough inside but still present.

 

Sounds like a plan. I'll try the 19's. Thanks.
