Supersprint exhaust

SS have dynoed an M3 with their full system and claim about 30Hp and 30+NM of gain! Now I have had exhausts installed on many of my cars (including a triple cat delete+ 3" piping in my WRX) and yes sometimes I have felt a hike in power and freer breathing of the engine but nothing close to this. Do you guys reckon this is actual data or just a marketing trick? Data and graphs are available at www.supersprint.com I think their original graph shows 300hp at the wheels which doesn't sound right.

marketing. There's no way it adds 30 hp.

Its insulting that they even put those numbers out there.

might as well be marketing a glass pack for Pep Boys.

i think the exhaust actually might be able to add 30hp and even if it doesn't it'll still sound nice

I had a straight exhaust(no-mufflers) for racing on my Cooper S and without an upgraded exhaust manifold it produced 19hp. That was on a 1.6L supercharged 200whp car, when I went to a rotrex charger, upgraded cylinder head, and custom exhaust manifold, it had a 20hp increase over my Magnaflow exhaust, which over stock has a 12hp increase. So a muffled FULL exhaust system on a 420hp V8, producing 30hp should be cake.

Sounds a bit too aggressive! Anything I think is possible but donīt see why no one else was able to and these guys yes. In fact, no one claims over 10hp really.

I think because everyone else is just has a cat-back system, while the SuperSprint is a FULL exhaust system (includes new catalytic converter). It's very surprising how restrictive factory systems and cats are. The more I look at it though, 27hp is a bit lofty. I'm sure more info will be out in the future.

on the optimism, but:

exhaust mods produce more significant gains on forced induction vehicles than on naturally aspirated cars.

Also, i would imagine that the mini's stock exhaust setup would be more conservative than the M3's stock setup. Therefore, an aftermarket setup could produce a more significant gain.

I hope that the +30hp info is correct. That would be awesome. However, I doubt it will produce 30 hp....just my2 cents.

True. Especially on turbo setups, and yeah hahaha the stock Cooper S exhaust was a restrictive so and so. I went from 1.25in inside diameter piping to 2.5in, and don't even get me started on the muffler setup haha, I bought the car for the soul purpose of modding and Autocross, and it's done it's job and then some.

I do also hope it creates that much power, but like I also stated a couple hours ago, it seems pretty lofty.

Yes, that sounds off for a steady state test. I don't see how there could be that much loss unless this is an acceleration test, but my German is too poor to figure that out. Here is a link to a steady-state test which rates it 378hp at the hubs.
