So I currently have the FRPP Sport Axle backs and I have started to get used to them. I am looking to make them louder, but I want to keep the deep rumble. Would Resonator deletes be the way to go? I've looked at LT headers but most of them seem to increase the pitch a lot and they're pricey.

 

Yes LT's are expensive but you gain a good amount of HP from them. They really wake up your exhaust system. You also need a tune to go along with them since you are no longer going to be running cats. I just put on the quad tip borla s types and love them. Loud deep rumble with some slight crackling/popping on decel. I still have my resonators in but may get them cut out this weekend...

 

Borla S type w/o resonators. Kinda crappy vid but should give you an idea.

 

Here was mine with sports and res delete ....I miss them
