did anybody ever do a dyno to see how much power a 2.5 exhaust make over this one? cause i have this exhaust and love it, very quiet and nice note when you get on it, but everybody says this exhaust is choking my s4 cams.

Back in the B13 infancy, it was believed that all cars needed back pressure hence the chambered design of the HKS muffler. If was more free flowing then stock and sounded more aggressive so people were content for about a year until the Trust(now Greddy) exhaust came out and was angled but a straight through design. Soon after, Borla, Dynomax Ultraflow and a few others followed the straight through design.

Anyway, we tested the different exhausts and found the Trust exhaust had more 3-4 gear pull then the HKS. The HKS back then was 2.25" and the Trust was only 2". Seeing these results consistently at the track and in times, people felt the HKS lacked the top end the straight through designed mufflers had. The stigma of chambered exhausts being more for bottom end stayed ever since.

But just think of how much more you'll make if you were running a 3 inch...You'll probably gain about 10-15whp.

I wouldn't necessarily say it's choking it , but it's definitely not running to its full potential.

Is it a rear section or just a muffler? Does it have the hangers on it? And will it fit a se-r? either way how much you looking to get?

Definitely would like to see pics.
