I thought I would just start a thread to answer any and all questions about the straight pipes/muffler delete mod.

Muffler delete - to remove the 4 OEM mufflers and replace them with a section of pipe, then use exhaust tips to finish it off. Some people choose to remove the stock resonator and some choose to leave it intact.

REMOVING THE STOCK RESONATOR WILL CREATE A DRONE. Let me say this again, if you remove the stock resonator, the car will be VERY loud and will drone at lower RPM's.

LEAVING THE RESONATOR IN THE SYSTEM WILL KEEP THE SYSTEM TAME EVEN WITH THE MUFFLERS REMOVED. If you remove the mufflers, but leave the stock resonators in place will open up the exhaust to have a very throaty, V8 power sound without being annoying at cruising speeds.

Straight Pipes - a lot people use this term, even myself, when referring to the muffler delete mod. As Diny pointed out in another thread, a true "straight pipe" system, it would have straight pipes from the headers back removing the cats, resonators, and mufflers.


Here are a few pictures of some muffler deleted cars.

4.You can see in this picture the stock resonator box is still intact sitting IN FRONT of the differential.



5. A very good example of before and after.








6.Here you can see the stock set up with the stock resonator.









Here are a few videos of the car WITH THE RESONATORS STILL INSTALLED. (Thank you JCM55555)

Thanks Tim.

Nobody should have any reservations about doing this modification (muffler delete) because you will most certainly be pleased with the sound and; if you're not the process is easily reversed.

So the question is...do they drone?!??! Cause I don't want drone!!111one

Hahah just kidding. Thanks for the thread! Hope this question never gets asked again.

Interestingly enough, I've been having trouble finding shops in the DC area who will perform a muffler delete. A Midas tried to tell me that it's illegal under EPA rules(riiiight), another one flat out refused. Both referred me to various custom exhaust shops. Funny but I don't see this as a true custom exhaust job. But whatever. I need to source tips and then get this done. Can't wait!

It's about time this gets added with the influx of straight pipe questions as of late. Thanks Timmay!

Permission to link to this thread to every "straight pipe" thread going forward.

I thought Timmay wasn't making them anymore which is why I asked.
He quit for a bit due to some pressure at work. He's started back up again but cant make them as fast as he was. If you have patience he can get to you and make you a set as well.

If I didnt get such a screamin deal and love the sound of my Dinan's so much, I would have a set too.

Thanks guys. I just figure with all of the question threads lately and with the increased amount of emails and PM's I've been getting lately, I might as well get some information together so we can just link this thread if it ever arises again.

Does the muffler delete effect the tuning? Do you need a re-tuen?
No.

There isn't a muffler swap that DOES effect tuning. You get absolutely no gain from swapping out JUST the mufflers. Now, changing headers, cats, AND a new muffler system, then yes, you will need some tuning.

Here are a couple more sound clips. It sounds good over YouTube but to be completely honest, it's ten times better when you're really there. :)

Jshep....lets meet up soon and make some noise. Some tandem GoPro video tunnel blasts through the I-90 tunnels would be very educational and pertinent to this thread :grinyes:

p.s. I thought your beast was white?
