Back pressure situation.

So I have my rear set of cats deleted. Just replaced it with pipe. And also am about to replace the muffle with a y pipe and new tips. Question though I have read that you dont have backpressure from this? Or are people talking about cutting it off at the cab? Question is, if I have my rear cats deleted and muffler deleted but pipe is ran (sealed) all the way to the tips do I still loose backpressure?

 

you will loose some bottom end grunt in exchange for top end power.

Not exactly the best thing for a truck meant to haul things.

 

also the sound will be pretty terrible IMO. very raspy and buzzy.

 

So ill just loose some torque? and gain HP?

Kinda like that?

 

I wouldn't really say you gain any. It would be so negligable. You will notice the loss down low though. And like chris said, no back pressure. Its all about how well the exhaust system scavenges the gasses out and away from the engine. Opening up the exhaust is not always a good thing, especially when N/A. The stock exhaust system does a good job of this.

 

Im already modded sorta. I took my cats out already and put a flowmaster 80 series dual. But I need something louder if you guys know of anything.

 

louder would be to chop off the muffler and straight pipe it. But like I said you will loose a tiny bit of power for more sound.

 

Just as long as its not a significent lost. Thanks guys!

 

You want it louder? I would hate to be your neighbor.

Flowmaster 40 series is about the loudest, most annoying sounding exhaust I know of.

 

besides zoomies of course

 

So pretty much every exhaust mod you loose power of some sort?

 

You should run straight pipe all the way back and end them with FMF Power Core 4's as each tip. That'll be sure to piss off the locals.

 

I just got 4's Ill put pictures up tomorrow

 

Hahahahahaha

 

Ewww, hate those vehicles with the loud exhausts. Sounds like a old beater. But to each their own. You will lose quiet a bit of low end as said before. And is that kid like 12 in that video?

 

The FMF may be quieter than what he has.

It will bark, but with the less than aggressive cam and ignition timing, plus the long pipe from the heads, it may take on a lawnmower / snow-blower sort of sound.
