Hi!
I am searching for an aftermarket catback and since I want to balance the weight of the car (left-right), I want to install a catback that exits from the right side.
Does anyone know, which exhaust is the lightest and exits through the right side?
TIA

The APEXi N1 Single exhaust should exit from the right side of the car, but keep in mind that the turbo and downpipe all are on the right side of the car. So it'll be balanced only if it's simply you in the car.

 

The balance I am looking for is of course with me in the car. RXTASY1 has an Apexi exhaust but it exits from the left. Is it the Apexi GT Spec?

How about the Trust Power Extreme II catback?

-Fanis

 

yes RXTASY's exhaust is the GT Spec, the N1 exits on the passenger side with a slight angle.

 

The power extreme II is a dual exhaust, I believe.

 

No it isn't. Look.

That's interesting, I've never seen that exhaust before. If that's the exhaust that you like, then go for it. The APEXi N1 is also single and also exits at the passenger side.

 

How good is the N1 power wise? Sound wise. (don't mind if its loud)
The trust exhausts are from the new line of trust products. They are probably not in the U.S. yet. I got the pics from the official trust website and since I don't know Japanese, I can't tell where they exit from. Where should I post my question to get a reliable answer?
Also are the Racing Beat 2.5 downpipe and presilencer compatible with the N1 or the Trust catbacks?

-Fanis

 

That is correct.
Trust does not officially bring in the TR-series of exhaust systems in the US through GReddy.

I don't think its possible to have a true dual exhaust with a turbo setup, most of the time its a Y pipe, just like stock.

But thats what a 3" downpipe and system is for thats as good as it gets for a turbo, and im sure its good enoughe.

 

Ted do the Trust and Apexi N1 catbacks need a 3'' exhaust system?
Where should I post my question to get a reliable answer about the Trust systems?
The jap forum?

Exits to right.

Thanks for the info and the link. I got the pics from the same source.
Where can I find out if the Trust exhausts (Power Extreme II - Power Evolution II) exit from the right side? It does't say anything on that on their site.

-Fanis

 

Yeah, it mentioned nothing about which side it exits.
Else, I would've mentioned it.

I tried to poke around a bit with a web search...

This is a listed for the Trust TR EVO, not the EVOII for the FC.
The description says it exists on the left.


-Ted

 

I guess that the only way of knowing is to email the manufacturer.
Ted do you have any other suggestions on a passenger side exit catback?
I know that the HKS Silent muffler exits from the left also...

-Fanis

 

Sorry, no, not anything easily available in the US.
There's a lot of options if you look at the Japan manufacturers - check out Fujitsubo, Espelier, Kakimoto, R.E. Amemiya, FEED, Panspeed, etc.
There's gotta be a single, right exit exhaust that will fit your needs.

I don't bother looking at the pre-made stuff anymore.
We built custom welded exhaust systems with easily available mufflers for our cars.
This gives us the most flexibility to build the exhaust matched for the performance of the car.

Even with the A'PEXi options, even the GT-spec uses a "tiny" 65mm flange, designed to mate with the stock cat.
Our exhaust systems are minimum 3" of 76mm, and we've been messing with 4" or 100mm pipes.
Typical mufflers are priced around $100 to $200 each, so our exhausts which use two mufflers are typically made within $300 to $400 for a 3" system and $600 to $700 for a 4" system.
We have a plasma cutter to handle making custom flanges, and both MIG and TIG welders to handle the welding duties.
