I would like to get some Borlas, but I went on their website and can't find them for a 370. Which ones seem to have the deepest sound? I don't want the whiney ricer tone.

play around in here for a bit.

I have. It's hard to tell from videos. To bad there aren't more Z's in my area with after- market exhausts.

I think I've decided on CAI and HFC's. I think I'm gonna go with the stillen cai. Which hfc's do you like the best?

i went with Berk HFC because of the extended O2 censor (your less likely to throw a CEL) but i went with the stillen CAI and then after that i got the agency power exhaust and that is very deep sounds kind of like an STI but more refined

Without the CBE your car is still gonna sound :shakes head:

I wouldnt say that, with HFC's my exhaust sounded way better than stock.

:iagree:

The HFC will sound better than stock but the CBE will give it the best sound out of all mods but it is also the most expensive one. Also IMO HFC will degrade somewhat quickly and start to sound raspy and you will have to replace them again or put up with the sound where the CBE wont do that. Right now the ERZ are the least expensive HFC but we are kinda waiting for a certain amount of miles on all HFCs to see how they fare over time, as if they wear out.

Now that I have finally got my ERZ HFCs on, I am actually thinking about putting the stock cats back on as I am kinda on the line about the volume and some raspyness. The FI CBE by itself sounded awesome.

all that hell to put them on and you wanna take them off? insanity!

I know huh! They do have a bit of rasp to them at time, then at other times they sound ok. But I can feel the difference they make so they wont come off till and only maybe, when I do the final drive upgrade. Need that Army money they owe me for the stop loss so I can do the final drive and lsd at once. Im off to NJ tomorrow for 3 weeks. You gonna be gone when I get back? Have to give me a call if so, to thank you for helping me here.
