Has anyone removed the mufflers and replaced with straight pipe in a Gen 4?

Just thinking that maybe someone has thought about trying this.
Just replacing the stock mufflers on a Gen 4 with Straight Pipe; has anyone tried this?
How did is sound? and what about drone sound?
Thanks

I did this with my old Gen 2 and was quite happy along with tons of other track mods but do not want it done on my Gen 4. It is a lot louder without the mufflers but you will get drone. The race cam and headers complimented the straight pipe sound but with stock cam Im not so sure. Its more of a preferred package deal.

Im actually thinking of doing the same with my exhaust setup plus belanger headers. For me, i want it real loud and i dont really mind the drone coz im used to it. Anyone did this or have videos on a gen 3/4?

I cranked my Gen III up with open headers just for the hell of it. It sounded great at idle, but WAY to loud at high RPM's (and I've had some straight pipe exhaust cars before).
It was fine on past cars, and would be fine with it on Gen II where the exhaust exits in the rear, but on a Gen III/IV, with the exhaust coming out right where you sit, it's just too much.

Did you get any cel light? Did it pass emmissions?

 

[TowDawg]

I never actually drove it, so I never tried to make it through emissions here, but it would have been fine here.
You're only going to get a CEL by deleting the cats (or certain brands of headers). I have M&M headers, no cats, and the Mopar Race Exhaust on mine. The CEL comes on initially, but all you do is get an SCT tuner that tricks the O2 sensors into thinking everything is fine, and no more CEL.
I wouldn't pass emissions in some states that use a "sniffer", but all they do here is check your gas cap and scan for any codes, so I'm good.

If I choose to try this I would be leaving the stock exhaust manifolds and cats on the car.
Gen IV can not get a SCT Tunner to program out the CEL.
Thanks for the info guys.

I replaced the mufflers on my 03 with straight pipe way back then. The inspiration came from this thread started by Viperfreak2 http://forums.viperclub.org/threads/556512-Easy-change!-and-it-sounds-GREAT! It did sound good and I ran that set up until I traded for my 06 FE. Roanoke sent the straight pipes back to me after the trade. I had saved the mufflers and they put it back to stock. I still have the straight pipes in the unopened box from Roanoke. They have been stored in a climate controlled area and probably still look fine. Free to anyone who wants them--just pay the freight. But I am not going to unpack, inspect, and re-pack them. Freight would probably be about $25 unless buyer is on the west coast. Sorry for the hijack, I know the OP is talking Gen4, not Gen3.

Is the exhaust pipes different size on the Gen III vs Gen IV ACR?
Thanks

No they are the same I put gen4 exhaust on my gen 3 bolted right up

Ok the 03-06 are not the same as the 08-10 there is 1" diference the 08-10 is longer than the 03-06 FYI. they can work with some work by cutting an 1" or adding, the muflers are the same but the cats are not.

 

[Green viper 1]

I put them on my car no problems no cutting

I have Belanger headers, high flow cats with Corsa exhaust on my GTS. I'm thinking about removing the resonators. Will this increase the sound without a lot of drone? Will it hurt performance or MPG?

Straight pipes went to FrgMstr and will ship tomorrow. Have fun!

This is my Gen III which has straight pipe after the primary cat. Still passes WI and CA emissions. I live in WI, car was sold in CA with "SMOG PASS" Stickers on it. Not sure the rules in CA, if they're just bs stickers or not. WI emissions is a simple OBD-II plug in. I'm not even in my thirties and its too loud for me
