Here's a clip of my exhaust system. It's custom 3in Magnaflow cat back
Stock cats, custom y pipe w dual flex pipes & midpipe.
It does sound good, but very quiet inside. What recommend
Too make it deeper & more throaty???

It depends on the exhaust setup.
There's no guarantee that TPs will make your exhaust deeper.
It will def be louder with TPs & most likely they will add more rasp.
Not to mention you will not pass CA smog with TPs.
HFCs on the other hand will pass CA smog and there's no gas smell with HFCs.
But HFCs can add rasp depending on the exhaust you have.

That being said the two exhausts I know of that got deeper with HFCs were ARK Grip & MotorDyne.
Not sure about TPs on those two exhausts.
Both are top of the line true dual xpipe exhausts.
If you want a deeper sound without rasp you'll need to change your exhaust setup.

 

Thanks guys! I will be getting high flow cats soon, ive got a new custom y pipe installed in rear till the tips. Which dramatically increased the sound so I'll be content till I can get my cats. I'll post a clip once it's complete.
Thanks again for ur advice!!!

 

Check it out!
I love my exhaust note.
