Trust me, with NA power it WONT make much difference and you won't notice a weight difference between the two. I helped a friend install is J's a day after I installed my Berk. I owned the Berk and loved it, only reason I departed from it was that I got too much attention

I don't know about all that Justin, just speaking from experience. I have a friend that has a full bolt on ap1 and me and him would run all the time and he would always start pulling on me in 3rd and 4th gear and end up at east 2 cars out by the time we shut down.

At the time I only had intake, test pipe, and a 70mm tb. Vs his, intake, header, J's racing 70rs titanium, SOS tb, test pipe.

When I got my J's racing titanium 70RS and he went to a titanium 70RR the amount he would pull on me definitely decreased a whole car and then we would lock vs him constantly pulling away. And this wasn't just a one time race as we always are running when we cruise.

I wonder if that was because he was making more power than you because of his efficient mods. My point being I'd rather have an exhaust that makes significant more power than being significantly less in weight. For every 10lbs lost you get 1 hp, functioning exhausts make 1-25+whp(pending application). The real question is which can make the most power

 

It's no question that of course his car was running better with his mods, I'm saying that with the exhaust my car started running better as well.

Plus it just sounds badass. I wish I would have dyno'd before and after the exhaust to see what kind of difference it made. But going from a stock cat back to a titanium cat back made a noticeable difference in my opinion.

Supposedly the stock cat-back is close to 60lbs, give or take. So I don't think either of the two will make a significant difference over the other in the area of power/weight.

 

Ive had both exhausts. The berk is just a fraction of the costs of a 70RR and sounds much better ( the 70RR has ear bleeding drone )

Soundwise, i loved both but the berk was the meanest of the two.

id go berk if i had to choose again.
