Looking for everyones input that have HFC installed. I am looking for one that does not give off any gas smell inside the car. I have kids that ride in the car so I dont want any gas smells inside the car. Which ones are you guys running that will accomplish this if any, i eventually want to go to the GST basemap+tbe. Right now Im on stock tune with evo x intercooler, licp, and depo uicp.

 

i have invidias tbe on my X no smell or smog or anything very quiet on idle but sounds awesome when you let it rip

 

With a hfc* lol

 

Gonna keep stock exhaust just replace cat with hfc, everything i have been reading says thats the choke point. You used the same brand for the HFC?

 

Yes that is the restriction point and its the same brand i know a girl with a ralliart that gutted out her cat and exhaust instead sounds sick too and runs fine with a road tune though

 

Depo Racing has a good one. I use it, and had the same requirement you did. I have a 3 week old son in the car, so not taking any chances.

$200

- 3" Stainless Steel Hi-flow Cat, why go test pipe, this will give you all the flow but not the gas smell...great for the street and weekend track days, why go test pipe.
- 200 cell metal substrate Catalytic converter. 100 cell is to close to a test pipe, no bebefit. 300 cell is more restrictive. 200 is just right...
- Efficient for 500+ whp
- Extended bung prevents Cels, Even pass inspection in some states
- Bolts up to stock or aftermarket exhaust

Thats actually the one I have been looking at, pretty good price. I have the depo uicp already. Good to know there is no gas smell from that one.

 

By the way did your RA throw a cel with the depo HFC?

 

Yeah. You can use an extender or disable it in the tune.

 

i have the CP-E tbe with hfc car sounds amazing and is awesome

 

I have been running the Ultimate Racing HFC for about 1 year/20k+ miles with no problems.

I have ran the Cobb Stage 2 the majority of time and also reflashed the OEM tune driving that way as well with no CEL's.

I have the interior fuel smell that seems to plague Evolutions and Ralliarts, but from my research/experience it is not exhaust related unless there is a leak.

Mitsubishi has other fuel emission vent issues they are not admitting...yet.
