Stebro questions...

For those who have or know about the stebro exhaust system (complete from exhaust manifold to muffler)...will this system be a good match for a NA engine with upgraded camshafts/valvetrain, injectors and the hydra EMS? Meaning will it be more of a hindrance to overall performance or will it allow a more efficient flow as opposed to the stock system? Thanks, Chris

I dont think anybody has the front portion of the Stebro system yet as it is almost brand new?

The system is designed very well and the only flow hinderance I would guess at would be the rear muffler as it is similar to the stock muffler.

The piping connects to it at a straight-on 90* angle, which could easily be improved upon.



FYI: I have the cat-back portion of the Stebro.

Re: Stebro questions...

Why pay so much for it though? You could get one custom built by one of the Tom's with almost the same performance gains!!

The Stebro has such a buttery-smooth sound. I have yet to hear something custom that comes close. (as far as sound is concerned)

Re: Stebro questions...

Sound and performance are always mixed w/ the 3.3

the #1 thing if you want power from the exhaust is the headers a nice 30" equal length header will do more than any cat-back. In this case sound are performance are a compromise.

I sacrificed a little flow from my exhaust by using a flowmaster muffler for a little better sound.

Stebro is nice for sound.... but prob not the best solution for power

I fully agree.

To answer Freeman's question: I didn't purchase my Stebro seperately, it came with the car

YT: I agree, the Stebro deffinetly isn't the best thing for performance. But I wouldn't trade mine for the world (of course, its also not on my "performance oriented" car so everything is all good).

Based on what was said above, it would be a hinderance to overall performance however it would allow a more efficient flow as opposed to the stock system.

Re: Stebro questions...

I wouldn't doubt that for a second it would be more sufficient than stock. The stock system can be much improved with new technology and through many experiments from other people. My argument was, why pay so much for a system when you can get one for cheaper with almost identical, if not better performance gains. Guess I got my answer. There is no comparison in sound when it comes to a stebro system. I imagine the sound is so distinct, that another stebro owner can note when someone else has a similar system!

Now if you wanted sound as well as gains in performance, it does not, in fact, have to be a sacrifice sound for performance situation. In a recent post, someone stated that they had an electronic cut out on their exhaust. This, I think, is a wonderful idea. You can keep everything sealed and quiet with great performance but at the flip of a switch, have an exhaust that announces that you are around, lol. I recently had one of these systems put in front of me, and my jaw dropped. If you want a world where sound and performance are there without sacrifice, check into the electric cut out..

Quoted for 100% truth.

Infact, even though the sound quality in my Stebro video is of very low quality; the first time I played it I had people running into my room telling me someone was outside starting my car!

I'll try and get a good recording of it sometime soon.

I hope you do. I admit, I enjoyed listening to it. In fact, I really haven't heard anything like it before. I was sitting at the counter with the laptop at my girlfriends place and turned the volume up.. She hated it..

Re: Stebro questions...

I'm with Dustin on this one.

My SVX also came with a Stebro. It's probably my favorite part of the car. I wouldn't give up for the world, I don't care if someone offered me MORE than what they cost new! The sound just feels like what the SVX SHOULD sound like...

Re: Stebro questions...

Would clearance be any harder at 28 or 29 inches?

No I wouldn't see why they would. It is harder to make them longer than 32 but to make them shorter would be relatively simple

Re: Stebro questions...

Those ELHs cost about as much as a catback though, don't they? Or are you planning on offering those as bolt ons as well? That would be awesome.

Bolt-in to what?? There is not a single part of the stock exhaust system I would put behind a set of ELH. Thats why I have not offered them as such
