I'm in the middle of a conversion (2.3-5.0) and I've purchased BBK longtubes and h-pipes. So after we finish I'm going to go straight to the muffler place and get them to finish it up. Each time I've been there they've always asked what brand and model I wanted. So what do you guys think? What is the best choice. I'm thinking the new flowmaster american thunder, although I'm not sure. So what does everyone think?

yep thunder flows are good

SLP makes a pretty mean catback not sure if you'd near there whole setup or not

u puttin cats on it? 2 or 4? u can get a really loud muffler shouldnt matter with cats cus either way its gunna be de-tuned a little

i got flows 40 series with 4 cats, stock headers (catback system) it sounds really mean in the 1500-2500 rpm range. its pretty quiet after that untill 3500 rpm's where the rumble kicks in

I have 0 cats, I have the BBK Long tube headers with the BBK highflow mid-pipes. What is the SLP you were talking about?
I got it, nevermind that question

source?

RacquetballRyan

i'd be interested in the source as well. Unless you were talking about the 5.0mustang magazine that you mentioned earlier, because then I'd already know.

SLP loudmouth sounds absolutely amazing on the 5.0
