+ 370z Muffler Delete +

^Yup, youre exactly right. All I did was reattach the stock muffler without the gaskets. But in place of the gaskets are a few washers on each bolt (4 on each bolt = 16 washers total).

Vegitto-kun

just go all the way and get rid of everything.

including the headers.

I want to know how the car sounds then

jtown82

that will hurt performance. not a single 370z pushing enough power that you would gain performance by removing the headers :P

ntm these cars dont come with headers stock. they come with exhaust manifolds

spearfish25

Not sure you want to keep the car that way. You'll have hot exhaust gases swirling around under the car. They can melt wires, discolor the underbody components and potentially get exhaust fumes inside the vehicle. You can always get some fab'ed tips like I did before doing a formal exhaust. (search for muffler delete and you'll see my threads)

If you want to save money and do a muffler delete (which I feel will net some small gains as the stock muffler is chambered and slightly restrictive), I would do some pipes with resontaotrs on it to help the noise some but still be free flowing and allow the deep tone. A muffler shop will be able to weld the resonators on the pipes real cheap like.

I see this mod as nothing more than wanting a more pleasing sound without spending $1500. It doesn't mean the people doing want to make their car sound more powerful than it is. They just want a better sound.

Zsteve

thats why I would do some pipes with resonators for a couple hundred max.

Yeah, could be. Different strokes for different folks, I guess. I have to confess that I often forget how important aesthetics are to some people, and sound is indeed an important aesthetic element.

i think it sounded good from the outside but the drone inside was enough for me to put it back on within 24 hours of removing i just saved up a bit and bought a real exhaust

Yep, everyone wants something different. I tried this out just to see what it was like and it wasn't bad at all. Now that I've installed resonated test pipes I'm pretty sure my muffler needs to stay on.

CBRich

He seperated the muffler section and then gapped it out with washers. So it's pretty much disconnected but still hanging back there.

Zsteve

I would say most of the exhaust fumes are still going thru the exhuast and mufflers, the gap is just letting the sound out more than anything and I think that is the purpose of it.

oh ok ahaha i was really lost for a while. so just that little gap changed the sound?

ddahron

^Yup, its basically a toned down version of a full muffler delete

Zsteve

Yea Semtex, I looked up ricer in the rice ionary and it came up with Semtex, and Zsteve. I guess buying useful parts and not destroying good parts is rice. LOL. But hey Im really a firm beleiver, that you do what you want to your car but and not worry about what others think as long as you are doing it cuz you want to and not cuz its what others do, so to each their own.
