my MBRP exhaust sounds like garbage

ok so i just recently replaced my stock straight pipe (cat and muffler cut out) with a 5 inch turbo back MBRP straight pipe. The stock straight pipe sounded good. The truck had that 6.0 crackle we all love. As soon as i put the MBRP on it sounds like crap. it doesnt have that deep throaty sound i expected and all 6.0s have. mine just sounds muffled and it doesnt rumble its just this ricer like sound that sprays out of the pipe. Even at 3500RPM it doesnt sound like my buddys 6.0 with a 4inch MBRP. His sounds WAY better I figured someone on here may have an idea, the guy who sold/installed the exhaust doesnt really know what to say. Its an MBRP aluminized 5inch turbo back with 6inch tip. I would have saved the $500 and left the stock straight pipe had i known it was going to sound like this.

If i was in your situation i'd take off the tip and see if it's any better.

If you don't like it then your next recourse is to return it.

I really don't think taking the tip off will make that much of a difference.

I was going to say the same thing as him
but since he already said it I actually have a question: does the 5" actually make a power difference over stock straight pipe? with the amount of mods you have on your truck?

I like pickup trucks, I like Fords, I like Ford pickup trucks, I like Broncos, Diesel Noises and Hydraulics.

Speaking from experience here I have had Stock 4in AFE 4in straight piped and muffled. 4in bully dog duals. 5in MBRP with and with out muffler and most recently 4in to 6in stack. For some reason the 5in MBRP straight pipe doesnt sound all that good. I put a muffler in and it got better but quieter. The stack sounded the best but is hard on long road trips. I just got my MBRP 4in duals straight pipe kit toady and will putting in tomorow. I have to say out of all of them the straight piped duals add a whole nother level to the 6.0 sound. You could try putting a muffler in it and see but it will get quieter.

Edit: Wow I think I just relized I have a problem^^^

The 4" doesn't suck and i don't think there is any performance gains from going to the 5"

I'd try anything that didn't cost me regardless of making sense or not. Remove the Tip 4 Million Chinese may just be wrong. Ricer Reference.

Hopefully this set of duals is my last exhaust. It doesnt make it any better but some of those kits were used on CL. I just picked them up to try somthing diffrent.
