Why fabricate new pipes when you can use your stock exhaust without any modifications? What I did was remove the gaskets and replace em with 3-4 washers. Your muffler will pretty much be detached. Ill post pics up whenever I can.

took me ~30 mins to do mine. i sprayed all the bolts and hangers/rubber mounts with WD-40 and everything came off flawless. since the initial vid i posted up in the 1st page i have gotten custom pipes/tips to finish it off. still waiting for an exhaust to make me want it.... big fan of Tanabe, waiting on them to see what route i will take.

heres my poor man's exhaust mod:


Sorry for the crappy pic. There is an internal flange so 3-4 washers should allow for the muffler to be fully detached, leaving about 3mm of space. The exhaust becomes loud at 2.5k-3k+ rpms and there is no drone except for when im cruisin at 70mph, but the drone goes away when im going faster than 70mph.

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)

How's that working out for you? Wouldn't it sound different from if you completely removed it?

Lol...I did this to the Range, would you call me a "ricer"? If it does sound good, what's wrong with wanting it without spending 10x as much?

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

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.

The stock muffler is huge and chambered so having no muffler will net some gains, how much, who knows, as the chambered muffler will cause ristriction. Even if you put a striaght thru muffler on you will net some gains. And if you just use resonators then you tame the volume some and dont mess with the flow, and in place of resonators you could just weld some larger diameter piping in to act like a res. Its all kinda rice for me but Im sure it would work for a cheap mod.

No, I'd call you a poser. But it's the same basic concept as a ricer. This mod is all show, no go, that's what's wrong with it. It's about making your car sound more powerful without actually being more powerful. I could be wrong, but nobody has done a before/after dyno to test for gains. But that's no surprise, because posers don't care about real gains, right? So why would a poser go through the trouble of doing dyno testing? Anyway, like I said, I'm just expressing my personal opinion. We can agree to disagree. If this "mod" floats your boat, more power to you. Maybe for your next mod, you can fake having a six-pack like this guy:

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.
