Celica Forums General Discussion Exterior TPR exhaust vs TRD dyno!

Ok just so everyone knows. This dyno was done a third party not a part of TPR. I lended this guy an exhaust and Intake to do dyno comparisons between the TPR and TRD exhausts. Both runs were done on the same GTS. Both had the TPR Intake as well. I took this picture of the dyno that he posted to post here. There is a thread in the Performance section of new celica.org from him. Anyway here it is. Blue is TPR, Red is TRD...

hmmm wonder why he never let me in on when he was going to do it ????

where can i buy a TPR exhaust ?

What are those gains over stock...or...what are the gains for the exhaust alone over stock. Are TPR Intakes and exhaust street legal for both emissions as well as the 95db limit on the exhaust?

mike, he told me that you were only available on the weekends??

Just so theres no confusion. The blue line is a dyno of TPR Intake and TPR exhaust, the red is a dyno of TPR Intake and TRD exhaust...

There is a group buy goin on over at New Celica.org ... if you would like to hop in on one, PM me.

TPR Intakes are street legal, just not carb legal. TPR exhausts are street legal and carry a 90 db test. 95 is the legal limit and TRD is 88, so you cant really hear a difference in loudness...

here is the thread with the dyno i did of TPR exhaust vs stock:
https://celicahobby.com/ubbthreads/thread.f_1870184300_0_collapsed_5__1.html

any other questions let me know

TPR exhausts are also CARB legal because they do not affect any emissions equipment. The exhaust dynoed a 10.5hp peak gain on a stock GTS, with even more power gained below peak.

can someone post a pic of the TPR exhaust? i wanna see what it looks like

there is a pic of the prototype in that thread that i linked. Please note the finished pieces are polished and the tip is different

yeah do you have the final product pic?

where's the pic?

i tried to order tpr and was told the price went up and he would contact me when i could buy an Intake...this was 3 months ago...

The very first production exhausts are almost finished being assembled for the first GB. Here are a couple pics of the unfinished prototype:

(ditch the space in new celica)

The actual production exhausts will be fully polished to a mirror shine like the muffler, will have a different tip, thicker mounting brackets, and a flange to make it a true bolt on exhaust. The only real things that will stay the same from the prototype are the muffler and the piping shape, assuring that the production exhausts will have same Performance as in the dyno.

i'll wait for the finished product pic before i think about ordering.

Yup, long story behind that. First off, about the long wait:

Basically, the original TPR machinist in MA screwed us over by working at slower than a snail's pace, then bent like 4 of our Intakes in a day (even trashed our designs for an underpanel ). So we promptly canned him and started a search for a better shop. We finally found a great one in CA with lots of connections in the industry. Next up was updating the design of the Intakes to fit and work better, since we had so many more resources at hand with the new shop.

The end result: strong stainless steel Intakes with adjustable mounting brackets for the best fit possible (both firsts for any Celica Intake! ), a custom made-for-TPR silicone coupler, and a custom made-for-TPR K&N filter with more filter area than the average K&N filter, and dual venturis to substantially improve airflow (also something not found on any other Celica Intake). The MAFS fins (yes, another first for the Celica! ) are also cast into the pipe instead of welded for superior durability.

The price increase:

There just wasn't enough of a profit being made at $150 to be able to start research on this exhaust (or the future TPR headers, midpipe, and internals). TPR didn't even have enough money for the initial stock vs TPR exhaust dyno (the above is an independent dyno done by Red01GTS from NCelica.org) at the time (all the Intake profits were used up making the TPR exhaust prototype), but we were lucky since EasyC had a hook up at a local dyno shop so he got a free run in. Still, the prices on TPR parts are lower than their competitors, and their Performance and reliability are tops in their respective categories.

The future:

Our shop is ready to send out the Intake prototype to EasyC this week, and as soon as he approves it, production will start. The pre-ordered polished Intakes will be made first (fastest to make), then the other colors. After production starts, there will be ZERO wait for the Intakes to be produced, since this new shop can handle high volume orders. Same goes for the TPR exhaust: they're already being made before payment comes in for GB1, so the only wait you'll ever have is for the GB to fill up. The first GB is already full, and the second one has started.

(remember to ditch the space between new celica )

i will order a TPR Intake for sure

Damn!! all the misgivings I had about the tpr Intake are gone now, with all that stuff you changed.

Sweet, just gotta get the bills outta the way and I'll be asking for one

so when i have my smog check done i wont have to worry about takn the TPR exhaust off?

These new TPR products are looking badass so far, great job!

GT dyno?

I can't see why it would cause any problems. It won't increase exhaust emissions, or decrease them for that matter. As long as the place you go to doesn't hate non-OEM parts, you'll be fine.

This is only the beginning.

Nope, sorry. Looks like Red01GTS only had a GTS to test. We were originally planning on dynoing one of EasyC's friend's GTs when he was on vacation a while back, but the dyno shop had to reschedule.

ahh its cool ive seen what i did for the GTS, so its probably just the same for the GT

very nice results...

damn, and i just put my TRD muffler on last week...

damn some one buy my Intake so i can start my project with tpr products

the question is, now that everyone knows injen losses so much power down low, who would buy it at a decent price of over 130 bucks.

So we've established the fact that TPR is one of the best street legal exhuast systems as far as gains are concerned.

How does the sound of the TPR compare with TSRM? You almost have me sold. If anyone could describe it or sound clip comparison, I would appreciate that very much.

Hell, people have known that about the Injen CAI for years, yet they still bought it. It's better because it makes 2-3 more hp than AEM for about 500 RPMs, and who drives below 7500 anyway? As long as you start the car at 6000 RPM every time you move from a start and stay in lift all the time, you'd never know the difference between Injen and AEM.

I'd say they sound pretty similar from the sound clips (never heard Tanabe or TPR in real life), but TPR is deeper, and quieter by 3dB. Here are sound clips from Turbo Magazine's Celica exhaust comparison:

wipe your mouth...you're dripping with sarcasm...lol

why not let lucky dyno them since we all trust him?

i don't know if that is possible. there was a a slap fight incident in new celica...lol

yea there was and i posted something to hopefully end everything...ill be speaking with mike (lucky) later tonight

LOL, some people just can't accept that there may be a product that performs better than the one they already have on thier cars. Especially if it doesn't have a name brand sticker on it like AEM, TRD, or Injen. There are TWO dynos now on TWO separate cars, and both show the same area of gains. Yet people think that they're both tampered with. Anyone on here care to dyno their cars with the TPR exhaust when they get it?

if you give me a cut j/p. i really like this exhaust. it's going to be really big

tell me about it... ...oh well it will just have to do for now...

I plan on getting every TPR Part!


Didn't someone say that you guys are planning for the N/A GTS people to hit 240whp?


I can't wait!

yes my goal is no longer 240, but 275 ...wit no nos

all your parts fit GT right?

^hope so...dumb question time but what's n/a?

naturally a(insert correct word) it just means you do all bolt ons

n/a means no Turbo naturally aspirated

ahh learn something new everyday

Naturally Aspirated...as opposed to F/I, Forced Induction (turbocharger or supercharger)

At that point, we'd need a TPR tranny to support that power.

Yup.:)

damnnnnn i cant wait to get the Intake, someone wants to buy my INJEN Intake, i hope i can sell it by next month, im so fucking exited about TPR (i love you guys) no im not fucking gay im just fucking happy that my dreams are finally coming true

nice work

WOW not bad at all.. I think I'll keep an Eye on the TPR.. thats incredible getting this reading over the TRD.. hum thats nice.. well lucky for me, I don't have an Exhaust yet.. better save up for this one.. but how much are they going to be??? and do you have a dyno test on the CAI?? Nice work, It looks to be very promising..

it's a good time to be just starting to mod...

I have started to mob my car.. but I'm doing reseach on the parts that I want to get.. I can't just put something in there just cause of the brand... every piece that you mod makes an effect... It all depends on the type of Race that you are going to run.. If the course is a full strech.. then by all means install parts that would give you high end power... but if you are going to play in a course that have a lot of twist, then your best weapon is acceleration.. so go ahead and install your AEM CAI, DC Sport 421 headers, and your TRD Exhaust.. hehe...

PS: I still want to see the Dyno Test on the TPR CAI...
