How could I overlook this thread???
Anyway I'll clarify my experiences and my customers experiences with my products as well as the waiting questions and what not.
1) The exhaust doesn't "move" the power band. Its a totally different band than TRD
or Stock. The design is significantly different than TRD
. Most people would lead you to believe that just having a free flowing exhaust will make the most power. While thats a big part of the equation, controlling gas velocity and direction can have a substantial effect on an exhaust's performance.
I'll start with bends, since its the most obvious. TRD
has 4 (approx) 90 degree bends in the piping as well as a 180 degree U bend in the muffler itself. This means the exhaust gas has to travel a total of 540 degrees of bends before exiting the tip. While TPR has 1 more bend, the total degrees of bends are less than that of TRD
coming in at approx. 450 degrees.
Next is exhaust gas direction. Obviously it requires more force for exhaust gas to change direction in a bend rather than continue in the same direction of a previous bend (pending the pipe length between them is short enough, otherwise it would be linear flow for both cases going into the bend). TRD
's bends are in this order, RIGHT, LEFT, RIGHT, LEFT, RIGHT (in the order of flange to tip). TPR's bends are RIGHT, RIGHT, RIGHT, RIGHT, LEFT (in the order of flange to tip, respectively)
Another crucial part of an exhausts performance is the muffler. I don't really know the compositional differences between my muffler and TRD
's so I can't really comment on that. I just know my muffler sounds great and dynos great.
With that all being said, I've had quite a large percent of the initial 10 customers who claimed a nice gain thru out the entire RPM band (low, mid, high). To say that I "sacrificed" one part of the band for the other is false. The exhaust did make 10.5 whp peak and 32whp at 6300 RPM ON MY CAR. Will everyone get that much, most likely not. My car seems to be somewhat of a beast when modded.
2) The Intake
pretty much speaks for itself. There are numerous customers out there with the Intakes
. If you do a search you will find nothing but good reviews on this site, teamcelica, and new celica.
Yes the Intake
did dyno with AEM
's low end and Injen
's high end. Yes those are confirmed as there was another celica member present during the runs.
3) The wait time. Well, I'm just an average guy who knows a few things about physics and cars. I love my car and saw that the aftermarket was somewhat lagging. So I decided to design something better, and consequently market it. I am NOT a millionare, hell, I'm not even well off. I didn't have the money up front to get 6 million things made for selling. The ultimate chain of events with shops screwing me over and taking my money didn't help either. Luckily I finally have a reliable shop that does quality work in a decent time frame. The exhausts are already shipping, however the amount that I did buy (which was more than needed initially) may have all the spots taken up (I'm gonna double check availability tonight). I'll be forced to do another group buy because of the financial mishaps with my previous shop (who turned out to be a fraud). There will be a post by me regarding TPR and its products sometime in the next couple days to alert everyone as to shipping status and production status and where I'll be taking it from there. But of course, as always, any orders will greatly help speed everything up. I'm open to questions.
