Im not feeling the exhaust.
I would wait for Apexi worldsports type of exhaust.
I just dont want to be "wanna-be-HONDA", even i had a honda!! hahahahah

 

i dont see why people are ragging it saying it looks on the lines of "rice cannon" etc

 

um, that doesnt really work. you need to do them back to back or else the numbers really dont mean ****

it was also brought to my attentiont that the dyno for the exhaust was done 5 hours apart. that is really too big of a window. you should try to do dyno runs within, at the most, two hours apart
just fyi

 

But dont you have to drive it for a while to let the computer adjust?

 

Yes you do have to drive it to allow the computer to adjust. Any time you take a baseline and throw on a performance part such as to allow more air to get in and out of the engine quicker will almost always yield power due to the car running leaner. That is the trick most performance part manufactures use to get their marked up claims with regards to hp increases. It's an old trick and one I don't fall for, so the method I plan on doing to test is most accurate. Also when I dyno I use the SAE correction factor so that the effects of the ambient temperature and pressure are removed from the readings. By using the dyno correction factor, power and torque readings can be directly compared to the readings taken on some other day, or even taken at some other altitude.

 

Neither do I... I think LMS did a great job, they angle cut the tips, not too big, not too small. Now if it was a 5" pipe that stook out 2" pass the rear bumper without the angled cut to follow the curve of the bumper then sure there'd be justification to rag on it.

 

I had the 94 TWIN TURBO SUPRA 6 spd. Targa with many mods. STOCK IS 320 HP!!!NOT 300HP.

 

He was referring to power at the wheels not power at the flywheel.

 

how much did the exhaust and intake cost.?

 

the exhaust havent been released yet. the intake cost $255 but theres a group buy on it right now for $230+$5 for shipping https://www.clublexus.com/forums/sho...d.php?t=198973

 

OHH MAN!

That exhaust looks completely worthless. I can see the weld mark they painted over with silver spray paint. You could buy those same mufflers off ebay for $50 each.

I also love the crush bent piping. You were probably better off with the stock exhaust piping.

As far as the intake goes, it looks good.

Im sorry to rag, but cmon people... we have LUXURY end performance cars. All of us are spending a decent amount of money on these cars... why cheap out when you are buying something like exhaust.

Just my 2 cents.

 

and where were you able to see this crush bend piping i couldnt see anything from the OPs pics, did you look at the dynos, it gave something over stock

 

See image .. 'Nuff Said.

 

i don't think they're rice cannons. they are coffee cans . i had similar muffler on my civic back in 95. they were Sebring muffler. ever time i see these coffee can mufflers, it reminds me of generic APC. i still like original TRUST exhaust and mufflers. LMS wants to charge $1,000.00 something for this? living in socal, they better come with CARB exempt stickers/certificates.

 

so you would rather have this? if you like stock exhaust thats power to you, oh wait you get less power. If the LMS exhaust gains can be redone on a different car that proves the stock exhaust is junk and ultra restrictive. This car needs a true dual exhaust system, unlike the junk merge pipe the IS has stock.

and as stated in the first post, stop complaining about a prototype:
