I want to buy an exhaust and have narrowed it down to stillen, borla or injen. I have a 5AT so I would really like the HP and torque to kick in in the lower RPMs. Does anyone know which one would be the best in regards to this?

 

So far from all the post of low end gain from exhaust. Stillen is NO.1 in the catagory.

- Auto/Nav/Premium/Sports/Aero
- 6 wire grounding kit

 

They all lose at low end. Stillen just loses the least. Here's the rundown on all of them. They were paraphrased from an actual comparison a mag did.

instaed of buying an exhaust get a JIC Y-pipe/High Flow Cats/ Crawford Plenum you will gain more power than any exhaust out and will cost right around the same

 

yeah but cats are illegal and I live in Cali.

 

Pot is illegal and you live in California...but it works wonders for Glaucoma.
