My Supra won't sound like a Cressida anymore

[Nick M]

I don't want a loud as fart pipe, or to look aftermarket. So that does not leave me with many choices. But HKS still sells their fairly quiet 75mm catback system. So now I have two mods done to my car. :love: This is a big jump for me you know.

A big thanks to the high quality service I got at Suprasport.com.

I will even do a before and after dyno, just so you can see how important a free flowing exhaust is on even nearly stock car.

 

[Mr.PFloyd]

you replace the turbo elbow?

 

[Nick M]

No. I won't be purchasing that. Well, not likely. I know it will be way better, but I may go the GT35R route. If I don't do it, I will get their elbow. I have the downpipe.

I have the HKS T-16 with HKS Turbo elbow - no cat - it spools a lot faster than stock!

This the same system as you're talking about?

 

[Nick M]

I have the off road down pipe from HKS. I don't know that they sell a downpipe with a cat. Yes, that mod alone made the car pick up much quicker, and the turbo came on much faster. Even with the stock cat back and turbo elbow in place. Boost went a little higher too. Before it pegged above that halfway mark at any point. Now, in 2nd, 3rd and 4th, the gauge is pegged with just the down pipe.

I will be putting on the catback when I get home in mid April. I don't know what the T-16 is.

T-16 is the HKS name for the whole system, from elbow back:

That one there - although the one i have has twin 75mm tails

wohhh what made you decide to mod your car? youve been stock since i-supra forums (does that place still exist?)

 

[Big Wang Bandit]

Congrats Nick!

Once I got a car I can actually mod rather than maintain, I started having tons of fun!

 

[Nick M]

Shaeff is still holding their hands on i-supra when they cross the street.

I know the original 3 inch system off road made 36 rwhp, on an otherwise bone stock 87. Having the cat in place cost it 6 rwhp. I can live with that. The old articles are all over the web.

I am even going to put a larger turbo on it. Why? Because.

So, old dogs do learn new tricks


Those pre-cats in the stock d/p are usually clogged something feirce.

 

[Nick M]

I saved the pipe for '08 when the IM-240 is enforced again. I should do a visual of the cats internals.

 

[Brewster]

Why would you want to but a larger turbo on it? You'll lose low end power.

 

[Nick M]

I don't think a LIPP/ITS or GT35R will cost me too much. Especially not with a higher stall speed. The GT35R needing a new manifold makes me question it. So I am not sure which one it will be yet.

The HKS 75mm Sport/Turbo exhaust is absolutely excellent. If my power goals were modest I would buy another one. My problem with it was that in Florida, the rain, sea-salted air and humidity just ate it apart. Mine rusted away.
It looks as close to stock as possible, even slightly more agressive, yet it sounds great.

If they made a stainless 95mm~ piping version of this, I'd be all over it. I don't know - living in Arizona now, I might even consider it again.

 

[Nick M]

The wifey tells me the system arrived at the house. So now I know I can put it on when I get home. I will even do a before and after dyno. These have been done, but new ones haven't been done in a long time.

 

[Nick M]

Check out the new pipes, with full coatings.

+1 for HKS for improving a product, and to SupraSport.com for supporting the community. I am not doing a before and after dyno. Those have been done in the past many times, it works.

 

[Kai]

Nick - thats exactly the same as mine - although mine obviously has no cat anywhere. They're a good system, quiet though, isnt it?

 

[Nick M]

No fart pipe sounds here.

 

[Kai]

Just that system and the HKS elbow makes building boost effortless...now if only the engine ran

You making fun of me

Looks great, almost stock but much better looking.
