Eisemann vs borla

Just wanted to know people option on Eisemann sport echaust vs Borla ATAK. Is it worth spending the extra money for Eisemann? My plans with the car are to only do exhaust, intake, tune and maybe a pulley.

The Eisenmann sport and ATAK arent in the same category as far as loudness goes. You mean the Eisenmann Race?

I mean as in performance. I was unaware that the ATAK was that much louder. Thanks for clearing that up.

Most people here will say you wont see much of an increase in performance unless you are eliminating the CATS. These are just mufflers so you wont see a noticeable increase in anything except sound.

Save your money on the intake and get test pipes, thats the cheapest way to get power and a tune will def enhance it.

I have to do emmisons so I'm trying to avoid that route. So you think intake is a waste? How about a filter?

Yea a drop in filter is a must. I have the green drop in one. Increased intake sound and a minimal increase in performance.

Interesting..... I guess it was too little to notice when I had my E. Race on.

Im guessing the Sport version doesnt give those kinds of gains though.

This is likely BS. Every other person on this post who has dynoed a cat back has shown zero to a few extra ponies.
