I did a muffler delete on my is 350 AWD . They just removed the stock axle back and replace it with a straight pipe and two tips without cutting my stock axle back .it sounds really good and louder than most axle back exhausts

Any drone? I experienced deafening drone in the cabin with this mod.

 

It has a very little drone and I drive on highway most of the time and I am ok with it.
I didn't remove resonators or secondary cats .

 

If you remove the resonators that sit behind the stock mufflers, you'll get very bad drone. I just had mine welded back in, it was unbearable on the freeway. If you just remove the stock mufflers, it should be ok. The main problem with this is the raspiness around 4-5k which I personally am not a fan of. I'm running all stock exhaust now with HKS mufflers and it sounds great with just a very slight drone around 2k which I can easily live with. No raspiness whatsoever. I'll post detailed pics and video clips later in a separate thread.

 

I am ok with the raspiness which I don't feel though:-) It sounds great for 350 but not for 250. and cost only 300$ (without cutting orginal muffler)
Post a video of your exhaust

 

Do you have any videos of the car in motion? The exhaust sounds totally different under load. The raspiness may not be that pronounced.

 

drone ... THIS IS AN EXPENSIVE CAR THOUGH..just my thought.. would anybody want to cut and weld the exhaust of 40+k car ?

 

I will make a video under motion soon . But I really like when the exhaust do some pops when the car slow down :-)

 

Very little drone with a nice loud sound . They didn't cut or weld my OEM exhaust . They just build a new axle back (straight pipe without muffler with two tips )
