that sucks man lol. got a friend with a borla exhaust i think and it does produce some rasp. dont remember if hes catless or catted. I haven't heard any rasp in mine which is why I love it but unfortunately I have to go catless

 

Do you have the GMPP performance? Twoozofjuice? Why is it you're wanting the one for sale on here?

 

Why do you have to go catless? No real reason for it.

 

Because his tuner said

 

He would see better gains by going with an actual header and a better flowing catback (nothing against the gmpp). But honestly with the mods he has listed theres ABSOLUTELY NO REASON TO GO CATLESS! If he has the zzp downpipe listed in his sig then he already has a high flow cat. Now having a 3 inch downpipe going into a 2.25 catback will cause some turbulence!

 

...I'm getting ready to order a catless 3" to swap out my catted 3"
--apparently 110 leaded and 14gph of meth is hard on the cat.

do you think my little 2.4 could see any gains rich?
I have a badass highflow intake, tune, meth, full 3"

 

In your case I think it could help some though mainly just due to the fuel your running. Also not all Hi flo cats are equal some hold up better. Some are ceramic some are spun metal. Some flow better etc etc.

Im uncertain to what flow rates the zzp hi flow convertors are rated at. But for twooz its fine. You knowing your goals and what your running Id probably ditch the cat. Your next bottleneck is probably the head as well as the badmab header. But would be awesome to see you hit your goal!

 

I'm on a 2.9 now but yeah I'm having a restriction in my airflow and its either my cat or my intake collapsing. But seeing as how zzp is out of stock on intakes might as well check if its the cat.

And yeah I have the performance one. I don't want the other one I was joking lol. I'm perfectly satisfied with how my exhaust sounds

And Iwanna get rid of that restriction asap cuz I'm trying to go e85

 

There's more restriction in your gmpp exhaust parts than your cat right now.

 

Prolly lol. Would replacing the piping with 2.5 help it?
