After reading the reviews, and by advice from many Borla owners, I decided that I'm going Borla. However, I want to know if anyone knows if I can get a rear dual out
(98 4x4 Off Road, 5.4 )
system cause I hate the dual out side look.

 

check borla.com It looks like there are maybe 3 different models with dual rear exits.

 

Yes, I too was looking for a Borla cat-back and I found one for ~500 stones, but I can't tell ya anymore because I really decided I want a Dynomax because of price and sound differences...I know that Borla is good quality, but I wasn't sure the sound would be aggressive enough for me...just my 2

Captain Windsor- just FYI, the Dynomax Ultra-flow is very throaty, and straight thru design also. Sounds great even with the 4 cats.

Yep! That's the one Max, I have made up my mind on the Ultra Flow system, now....just gotta fully convince the bride that this exhaust mod will all be to HER advantage (somehow???)....

 

My wife likes it, but she is a car nut too. It is most quiet at idle, medium at highway speed, and has a substantial growl under acceleration; varied by load and rpm. I've got many compliments and have no loss of low end.
