Am I delusional?
Am I delusional?
My goal: I am very interested in picking up 18 HP or approximately a 5% increase via an exhaust modification. My expectations 1) Keeping the db level no greater inside the cabin on longer freeway trips. My better half is less than thrilled with overall cabin noise on the freeway. On the twistys she is fine, so I don't care. 2) It bolts on. No problems. My stock exhaust produces no dash lights, O2 sensors etc. If the mod makes for a tinkerer's delight, then I won't be satisfied. 3) I live in California with a bi-annual registration smog law, so I must meet regulations, without on-off catalysts. This will cost HP but how much? Things cost what they cost, so let's not make this the issue. Many of my needs were addressed here in this well-written review. So Stillen would be first choice, but the above-stated requirements trump a brand name. http://www.the370z.com/intake-exhaus...-pictures.html Thank you. |
I have the Stillen CBE and I love the way it sounds. Not too loud, but a nice gutteral sound at start up and when you get on it. There is no drone when cruising on the highway either. Stillen claims 18 hp and I am sure that there was a noticable increase in power but since I haven't had it dyno'd I can't say that the 18 is correct. I think others here have seen the claimed 18 hp. Some say that the tips stick out too far but I think it is just right. The other good thing is that they have them in stock and can get them too you in just a few days. I hate waiting for a part after I decide to purchase it and I was very pleased with the shipping time. I had Stillen ship it to the shop that installed it as well. It's a great exhaust and it doesn't stick down any more than the stock unit, which was important to me. Go for it!

Sounds like the Stillen is your ticket. Or a Berk too. A FI with 18" Resonators and stock cats could also be a good option.
|
I just sold my 18" FI exhaust because it was a little to deep in the low rpms, you know, like just puttzing around town. I was in your shoes 10 month ago and while I enjoyed the FI exhaust, in the end it proved wrong for me. It seems like their is no exhaust that can bridge the volume gap between stock and stillen/18" FI. One day maybe.

The Stillen CBE is great. No drone at all, good power increase of 15+ whp, bolts right on, and is nearly as quiet as stock under about 3500rpm. Some people have complained about the tips protruding...but they are adjustable and if you don't push the rear section all the way in of course they will protrude. I have been VERY happy with it, I wanted a better sound and power but I didn't want it to be annoying when just driving around town. It looks cool too.

I really wish I could hear the stillen locally
|
stillen vs fast intentions is like night and day. All about personal opinion. I like fast intentions because it sounds good, good hp and looks amazing. Stillen almost sounds like stock and tips stick out way to much
|
You'll like the Stillen. I have trouble believing the published gains given the Y pipe and bend angles in the system, but it produces a very nice exhuast note that is relatively quiet until you get on it. Keep in mind you'll add weight vs. reducing it from stock.
I have to say that the FI (I have 12") resonators is very civilized at cruising speeds. When you get on it, it wails. My wife says she gets a "tingle". I think that is a good thing. |

The tips will stick out too much if you install it wrong, but the tips absolutely do not stick out otherwise. I installed it properly the first time and without ANY experience doing any kind of car maintenance/modding. |

go get some washers, 3/8". 2-6 per exhaust bolt as per desired volume. adds about 30rwhp when installed
|
How come no one is suggesting the HKS Hi Power?
|
Thank you all for your input. It does seem that the Stillen will fill my needs, including the need to ride high off the ground for clearance.
I hope that this statement is true. It seems dubious that another two thirds gain can be made by adding washers. And will this make the exhaust pipe tips stick out? Quote:

He's being sarcastic!

PowerHouse Amuse baby. The R1 with the Y Pipe will get you your 18HP. They say the R1 is the louder of than their Super Silent one, but it is not lound at all and produces the PERFECT sound; not to mention it weigh less than all the other exhaust you will find due to the titanium.
The only downside is the cost! |
Why do the exhaust. My Stillen intake gave me 20 RWHP.
With no other mod's It was the first one i did. Base line as 264. with inake 284. +20 rwhp. It sounds great and it works. It produces then most rwhp per dollar invested in the car. Do the Berk cats next. Great rwhp for the money spent. Save the exhaust for last as it cost the most. Z |
He is in Cali. Cats may pose an issue......
|
So i just ordered the HKS Hi Power.. Hopefully have some reviews this weekend.

Mt Tam I am - you really should look at this system. |
If you do.. i must say, dealing with Nick at THM was pretty awesome. Also, two other vendors i were talking to were very very supportive and quit to respond to my PM. They were Imported Performance and Nissangeneration
