thanks drh

 

I've had my speedtech exhaust for 6 months and love it. Coming from the stock exhaust, it is much louder (i routinely set off car alarms) with only minimal drone. It has a deeper sound than most aftermarket exhausts i've heard. The shop that installed it didn't have any major problems, but they said it took a little adjusting to get the cans to hang evenly. This exhaust also dyno'ed at peak of 41 hp over stock, which is the most increase i've seen objectively for an aftermarket exhaust.
The only thing you should know is that the exhaust tips do stick out farther than the stock exhaust. I actually like the way that looks. Quality of the product is excellent as well as the customer service. I highly recommend it.

everyone has different opinions & expectations... but overall I think the speedtech exhaust is 2 thumbs up.

 

I like mine, not that I couldn't find a nit or two to pick but that's all just nits, nothing really worth complaining about.
Although, it would have been much nicer if I could have just put the box under the car and had it attach itself while I was sleeping. Now that would make it just about perfect.

 

Any "moron" that can read would have noted that I only confirmed the exhaust is on the quiet side and without drone which is what I was looking for. There were a few raves on how great the exhaust sounded, but how something sounds can't be heard by reading. The videos of aftermarket exhaust all sound alike to me.

Any "moron" that can read would have noted that this purchase was made after reading the good reviews on this board. My review just stated the facts that I encountered, just because I don't think the "System ROCKS" and I am not "tickled" with it doesn't mean it's a not a good buy. I stated that this exhaust is the best bang for your buck and much better than stock but it's just not for me.

I also read that this exhaust might have loss of power, but that's not something to be quantified by reading a forumn. I didn't think I would lose .1 to .2 bars of boost.

All my other "experience" are valid and even confirm by some great writers of technical info books, new muffer band would have been easier, tips has the ability to fit more flush with the body, etc.

Now this isn't all that big of a deal, but I just stated my experience. I made payment on a sat, having modded cars and dealt with countless vendors before I expected the product to ship by mon/tues. On thursday when nothing arrived and being friday was july 4th, I asked for a tracking number and was told that the exhaust would ship next week. It seemed excessive to me as upon receipt of payment a simple email letting me know it was going to take a week to ship would have been nice. I guess that's hard for some nitwit (I can use adjectives too!) to understand.

Just because one doesn't find what you liked to "rock" doesn't mean you have to get all excited and start with the sly comments just to feel secure with your purchase (I know how to sly comments too!).

Again, the Speedtech exhaust is the best bang for your buck. Better than stock and only way to know if you will love it is to try it out yourself.

Sincerely,

T

 

It's common knowledge that it takes a week for a Chinese boy in shackles to weld together an exhaust like this. Thanks for the believeable review.

In saying this, you're pretty much telling those of us who are very happy with the performance, quality, and sound of our Speedtechs and who have reported those posts here, that we aren't "believable?"

Anytime you find yourself near Washington DC or Richmond Va. let me know and we can schedule a little time for you to sample my exhaust in person...Then you can give an "honest" review first hand.

Imola, Good luck on your search for the best system for you. No hard feelings, just didn't care for the tone of the thread... But as others posted, you're in titled to your opinion

I'm done with this thread.

 

no hard feelings ever.

Cheers

 

We are all entitled to our own opinions. For the record, i love my DGI. coming from a loud *** fabspeed, the dgi is quieter. its exactly in the middle between the abnormally quiet stock system and the ridiculously ricey fabspeed loud. I would easily value this system at 3k. the fact that its under 2k makes it such a great deal.

Im sure just by changing from the fabspeed loud, to DGI, (theoretically for sure by design differences) i lost a couple horsepower. i can confirm that it wasnt anything substantial at all. probably 5 hp... just a guess....

i actually duplicated my last year 11.4, 11.5, 11.6 at 128ish... last year were done with a fabspeed, this year with a dgi exhaust.. very similar results...

actually in favor of the dgi, this year, the 1/4 mile runs were done at 80 deg.. last year with fabspeed at 50 deg. my setup has been very similar as well.

this year better launches, stickier pavement, last year colder weather. it all cancels out and i conclude that in terms of results i did not loose any time in the 1/4 mile by changing exhausts...

 

That wasn't my intention. I was simply glad to hear a few non-positives about the exhaust like the straps, tips, and the silencer rings to balance out your holy of the holy reviews. I've read all your posts on this exhaust (multiple threads) as well and enjoyed reading them. I'll definitely take you up on your offer next time I'm in the DC area!

Cheers,

First of all, I would like to state that exhausts are personal and not everyone is going to be happy with every exhaust. We have developed an exhaust in an attempt to appeal to the vast majority of users and based on our feedback, I think we have suceeded with our goal. We have many very satisfied customers. My personal experience is that I have heard and/or purchased several 996TT exhausts, some costing 3 times as much as the SpeedTech and I have yet to hear one that I prefer over the SpeedTech, regardless of cost. Most are either too loud or have too much drone. We have tried to address these issues, as best we could in developing our product. When you produce a performance exhaust with the goal of higher horsepower, quicker spool, etc. - you are going to get more noise. If you want it to sound like stock, then you should keep the stock exhaust because any aftermarket performance exhaust is going to be louder and make more noise. That's just how it is.

We learn from comments about our product, both positive and negative and strive to improve it as best we can. Our goal is to provide a fantastic product at a great price and overall, I am happy with what I have seen so far. Although this is a second business for me, I do not treat it as a part time thing and take it very seriously. We have some exciting things planned for the near future that will will show our determination to succeed and grow.

I would also like to correct some some mis-information contained within this thread. The SpeedTech exhaust is a full 70mm flow through system - not chambered. If you were to put a ball in the tail pipe, it will roll to the cat with a clunk and roll back - full 70mm, flow through design, thus the power we dyno...

When Stephen at IA did the 996TT exhaust shootout a few years ago, the older Fabspeed was the highest dynoing exhaust and it made approx 40 HP at it's peak. Nothing else was at that level and the SpeedTech was not available then. If you look at the dyno sheet of the SpeedTech below, it is almost identical to the fabspeed winning shootout dyno of yesteryear. I do not know of any other exhaust producing these numbers. What I do know is that a competitive exhaust was dynoed on the same dyno as the SpeedTech and compared to stock only produced approx. an additional 13HP. That said, the SpeedTech has proven to make power and because it's quiter, perhaps it feels slower by comparison to some former Fabspeed users. I think this could be similar to a drag strip run where you really light them up and hear all kinds of squealing and you think "that was fast" and the time slip shows one of your slowest runs -it sounded fast, though.

Imolas54, I really wish your experience could have been everything you hoped for. I have done my best to bring a great performing, superior sounding exhaust to market at a great price. Yes, the tips do stick out a little more than stock (maybe an inch). Frankly, I did not even realize it until someone mentioned it. Like JB, I happen to like it, but IMO it's barely noticable. I also would like to thank you for your positive comments and yes, it was our goal to be "best bang for the buck" and quieter than most and it appears we have unanimously achieved that goal. If I can be of any further assistance, you have my email - feel free to contact me. Our goal is happy customers and I will do my best...

Here is a copy of the SpeedTech dyno. It is for all intents and purposes equal to the highest HP increase over a stock exhaust dyno I have ever seen for a 996TT and shows more gain than most systems.

 

Thanks for the Info John.

Anyone have any idea why I would be running less boost now thou? what I can do to get it back?

Thanks

 

Imolas,

You're welcome. In reference to the boost issue, we have had some extremely hot, humid weather in the NE the past week or so. My car cuts back on the boost in warmer weather, but since I have a Greddy boost controller, I can turn it up and keep the boost I desire. When it cools back down, I then have to turn the Greddy down a bit, as I will see higher boost than when it is hot and humid. It could be the weather.

Installation of a boost controller would give you the ability to specify boost regardless of weather conditions.

 

Doesn't free flowing exhaust make less boost due to less backpressure? I bet the turbo is still pushing out the same amount of volume of air but since you have a free flowing exhaust, its spits it out faster causing less backpressure. But im not sure where the boost is actually measured or even how, which makes a difference.
