The 3" Scorpion exhaust system has arrived and I have unboxed everything and it looks sweet! It looks beautiful and is above average quality (welds and all). I will post pictures tonight of the uninstalled system. It *appears* that the tips are going to be long enough, by my crude measuring tape fitting. If anything they might need to be lengthened 1 inch. I have an appointment with Cobb Plano at 11am tomorrow (Friday) for a base line dyno session and looking into the map differences between 91 and 93 octane tunes. I will then have the system installed and return later in the afternoon for another dyno test of the exhaust system. Looks like the FSWERKs intake will arrive on Monday and I will install it and then go back to Cobb again for yet another dyno session. The only bit of bad news is that I accidently ruined my COBB AP screen when I was taking measurements of the stock system. Chris @ Cobb Tuning is going to send it back to HQ for a refurbish. Turn around will be quick (I hope).

Any weight savings?

Essex Parts in North Carolina is their U.S. distributor, although they are looking for other vendors to carry their systems. Ummm, as far as I know, they have another system in stock... no waiting. ~grins~

It's 5.17 pounds lighter than the stock system

That sounds pretty sweet ! But I'm not sure I get a clear picture of how it sounds being driven.

I really like the low end tone, I am not too keen on the tone at higher rpm. Too much ZzzzZZZzz for my taste.

Guess i'm in the minority. I like (read--> prefer) a nice raspy rumble. I don't think a raspy rumble is the same as a Honda fart can.

You can have a cheap crackley Honda fart rasp... Or you can have a nice deep throaty raspy rumble. Something a lot more at home in a v8. Give me the sound of the old R32's ?

I don't like too much "buzzing" for the FiST's.... or any 4 cyl for that matter.. Starts to sound too much like a toy to me and funny but I personally view that as more ricey.... I guess it depends on where you live?

(Not saying that yours sounds like that at all pelotonracer !) I really enjoy the low tones. I am unsure how I feel about the higher RPM tones... I'll reserve judgement until you post more !

I think this ones a close 2nd fav so far.

But tbh, there isn't an exhaust that is quite what I'm hoping for currently.

Anyway , sweet setup you got there

That idle & low end... :wacky:

Ok, the exhaust sounds great... but I see this all over the place in the forums, why don't people like raspy exhaust? I came from BMWs and the rasp sounds amazing... is it just 4 cyl engines that sound bad with raspy exhaust?

Some people don't understand that there is a difference between sounding LOUD, and sounding GOOD.

Excellent

I need to know how the sound level is. My main concern is any droning at highway speeds or really any speed from 45-70.

Apparently I need to read the whole thread LOL. Thanks for the great info.

I only revved the engine to 5-5.5k. It sounds great at redline (to me at least). However, I was trying to not draw too much attention to myself so I didn't rev it as high as I could have. heh

I wonder what the Scorpion system sans resonator "can" would sound like... I bet it would sound a bit raspier (and louder). Or maybe the addition of a de-catted DP. There is a fine balance between "sound" quality, loudness, drone AND power production. If I removed the resonator, I bet it would be louder and have more rasp to it... but at the expense of drone. There will always be a design compromise between the four. This particular exhaust system has the best compromise between "tone" (nice sounding) & "drone" (there is none). I don't know about power... yet.

I like that I can be driving down the road in economy mode and hear nothing, but when I mash the pedal, it sounds really good. This one seems to be "tuned" REALLY well, but without harshness or drone (something that is very important to me). It's also important to note that other than the exhaust system and Cobb stage 1 tune, my car is bone stock (other than a Cobb panel filter). I have a feeling the exhaust note is going to change again (perhaps significantly) once I install the FSWERKs intake. I'll know soon.

Yeah, I gotta say, the sound is growing on me the more I listen to it.
I must be babying my car too much.. I don't think I've seen 5.5k rpm too often.

You have got me curious now about the sound w/o resonator. That could go in either direction I think! Either veryyy nice, or too much. Make sure you post up if you ever experiment.

Your car is turning out fantastic... If my lady was in the market for a car I'd have to find a way to convince her to put a silver ST in the garage. Rarely ever like Silver cars, but I don't mind saying it over and over.. the ST wears it so well.

Thanks bud. I really like the Green too actually. It is my 3rd favorite color behind white (my favorite) and silver. I've never seen a Green one anywhere. I've seen all the colors except the Green Envy. I've seen a lot of pictures though.

I'm hung up on funds atm too, so it looks like I will have to postpone a dyno test on the exhaust until next week. :meh: I REALLY wanted to put my FSWERKs intake on the car. It's been sitting here since Monday and it's getting in the way. lol :biglaugh:

Well, in 12 hours it will be the day of reckoning for the Scorpion system as I head back to the dyno and test it against my baseline. I will post dyno results when I get back. Hopefully I can bolt on the intake as well and test it too, but probably won't happen tomorrow.

Sure, post that you are GOING to post something in 12+ hours.....

Tease. :troll:

Yeah, we are trying to figure it out...

All the writers in the auto magazines seem to like the Alfa 4c exhaust note. Its a 1.75l turbo direct injection Dodge motor without a muffler. It might have a resonator and probably has a cat.

If our 1.6 is given similar hardware, we should be able to tune the Ti-VCT for similar exhaust sound.

The sound of performance is what excites. For Americans that's a deep rumbling V8 with a choppy idle. As direct injected and turbocharged I4 engines become the new performance paradigm, their sound is going to grow on people.
