08 IS250 Straight Pipe?
hey all, new to the forum 
, so I have a 2008 is250, and i was wondering if anyone on here has straight piped their 250? and if so, how much was deleted? like res and muffler? im planning to do that soon because its insanely quiet with the oem exhaust. thanks in advance!

Res and muffler delete on my 07 350. Cabin noise is pretty annoying at 2-3000rpm. Really quiet at idle. Paid around 2-250 for pipes tips and labor altogether. If I could, I wouldn't have done the deletes; instead I should have saved for aftermarket setup instead.

Do you think if I just delete muffler and replace with pipes and keep the res on, would it reduce the drone?

I have a 07 250 AWD with a muffler delete. Bought 2 4" muffler tips with 2.5" inlet off eBay and went to a shop to get the muffler delete done. At first it sounded really nice and loud but then it started to become more quiet as time passed by. So now it sounds loudish at 2-3k rpm and then after that its not as loud. Sucks that invidia didnt make a midpipe for the awd models now that I see people mentioning that they would buy one if one was available. My 3 options at this point well more like 1.5 are to either get M2 mufflers and delete the resonator, get a glasspack and have a shop weld it in place of the resonator, or just simply delete the resonator and call it a day. But then again I feel it would be a waste to spend almost 300 bucks when i couldve just bought the mufflers awhile back and done it differently. So now its either delete the resonator or get a glass pack in place. So i have to do some research if a glasspack will be worth it or not. Buddy of mine had the invidia midpipe modified to fit at a shop for his awd and he told me he regrets it after spending over 200 bucks to be installed and what not.
