I am considering getting a high flow cat with new exhaust. Are there any options with little drone? Everything I am reading is saying test and downpipes are the biggest factor to cabin noise. My goal is something as close to stock as possible while improving flow. Ets v2 quiet will be my exhaust.

 

Loving my ams HFC just can't seem to get rid of this damn cel even with a spacer bummer

 

Does your CEL stay on or turns off at times?

 

just disable it via open ecu

 

My setup is ETS V2 Quiet with AMS HFC. Minimal drone around 65-75 MPH. This is on a GSR in 5th gear.

@Beetle Orange I had mine turned off with my tuner after my tune. I bought the spacer but never had it installed.

 

It's really only bad when you completely let off the gas and coast. I have to go over a mountain on my way to work and going down I coast around 70-80mph and it gets old really fast

 

T1R Sparrow Exhaust System is nice and quiet almost like stock, a HFC should make it a bit louder.

 

If you're getting the ETS catback you may as well just get the ETS HFC too so it's a matched system. They should all be compatible with one another, but this way if you have a problem you'll have only one place to go for the solution.

 

when it was still a bit warmer, it was on and off but now it hasnt gone away. my thinking is, the 02 is not getting "hot" enough.

my question to those that turn them off via whatever tool, will you still pass emissions?

 

Yup I noticed mine was rattling a bit by it hitting the drive shaft. Took it back to RRE where it was installed and they moved it over a bit and no problems since then. I should have went all ETS but bought the AMS for really cheap.
