Haha. my car backfires/whatever whenever I let of the gas. You should hear it with the cut-out open..sometimes it sounds like someone hit under my car with a hammer. (like you can feel it).

I know its normal for a no lift shift, one pop good more than one bad.
Also i believe its a function of a having a forced induction (turbo) vehicle, its related to pressure,combustion, and timing i dont remember all the technical crap on why, but thats the lamens version. as u retune and upgrade parts it will amplyfy the sound and oftenness.

Would an ss/tc sound good with catless dp, muffler delete and resonator delete? I love the way my friend's srt4 sounds and he just has straight pipes. I know catless and muffler delete sounds awesome, im just not sure if anyone's done resonator delete as well.

Most of my vids where private, so I fixed that. SC was a custom Magnaflow catback (full 2.5) with 2 mufflers and the Vibrant H/Dp.

the backfire is the result of unburnt gas in your exhaust system being ignited, hence the fireball. If you want loud, or lots of fire, try a race prepped rx-7 rotary. Loudest commercial engine ever with enough flames to illuminate the road behind you. If you want lots of fireballs, install a two step rev limiter, which intentionally halts the spark every other cycle and dumps the gas into your exhaust, creating the flames you saw in those videos.

Something with the injectors on SRT4's... they pulse or something and leave more fuel leftover to be burnt
