3 inch single exhaust.

I have my setup planned and all the parts are ordered and on their way. I just wanted some last minute suggestions to try to make my exhaust sound good and not be TOO loud. I like loud but now Im having doubts about going to loud. It does annoy me sometimes and makes me not want to drive my car (along with the stiff suspension).

This is the muffler I picked (the bigger one):


Instead of going with a resonator I bought 2 vibrant race mufflers.


Both are 3" I/O and 5" in length.

Piping is all 3 inch stainless steel (frigging pricey!!!). I bought 6 feet in straight piping and 2 U-bends as per directed by my friend who will be welding my exhaust system together. The system wont be mandrel bent just all welded up with the pre bends. Each straight pipe is 2 feet in length. I also have a 6" long flex pipe. All this will be mated to a small megaphone that goes from 2.5" to 3". that will be welded on the 2-1 collector on the y-pipe. That will be the only stock part on the y-pipe.

where should I put the mufflers? From reading around I figured I should put one on the y-pipe where it begins to flare out at 3". Im pretty set on putting one there but where should I put the other 1? I read somewhere that 2 mufflers next to each other will make it sound nasty.

My last question is, should i put a little jdm tilt (kinda gay but im serious)?

Id rock the hello kitty.

I'm not touching the bumper. I really don't care for the cut out being empty. Aslong as the muffler looks good and I get power over stock ill be happy.

Interestingly, just on the way to work this morning I saw a 2.5S with the stock dual-tip but a 3.5 bumper. Did not look good, but that single tip looks decent.

subscribed for results, and to tell you to NOT put the tilt on it I personally hate the way tilted exhaust look on cars, but you are the one who has to look at it every day, so do what makes you happy. it would be +1 for uniqueness though.

what about cutting the rear bumper so that it is a straight line from hole to hole if that makes any sense

I like the tip though. good luck to you


would like to thank birdturd for the nice chop

Its going to be loud man, those 'mufflers' are just straight through so they aren't going to do much for sound reduction. Your guy should show you both options on how to mount the muffler, have him hold it while you stand back and look at it, whatever suits you is what's best. I think it may look okay tilted, but I'd have to see it to know for sure.

Get some vids up when its all done

Don't to the JDM tilt and suffer the same fate I did

What I do think is somewhat of a compromise, especially on a dual exit bumper, is if the muffler(s) is or are tilted horizontally each on opposite sides with NO tilt, but NOT upward at an angle AND tilted.

Like this, this is from a 350z, I think THAT looks appropriate AND sexy:

Yeah, its gonna be really loud still. I have 4 dynomax ultra-flo mufflers on mine. Two bullet-style in the 3in section instead of a resonator and the two rectangular mufflers at the back (I have 3in split into dual 2.5in). I only went with the dual outlet b/c I wanted it to look right with the bumper. If I could have found a 2.5 bumper for cheap at the time, I would've gone single outlet. It seemed like the drone actually got slightly worse when I added the two bullets, but they got rid of the rasp in normal driving, which is what I was goin for.

Heres my exhaust thread from a while back: http://www.nissanclub.com/forums/mem...-thread-2.html

It has pics of the placement of the bullets and clearance. If you can't see exactly where they are from the pics, I can take some measurements, let me know. My first bullet is nowhere near the y-pipe, though. Its well into the straight section. The second bullet is after the small chassis brace where the exhaust system slopes downward.

The bullets your using probably won't cut down on much. I went with a 16" AND a 12" and like I said, its still loud as hell.

Leathe- I see you let your super secret project slip out... Should be badass! one of a kind for sure. I like.

Whenever I redo my exhaust down the road I'm seriously considering giving a Greddy Ti-C a slight up and right tilt. Not too crazy or aggressive of an angle, because then it's just tacky. I would do it man, as long as you post some pics!

If I do tilt it its def not going to be like a civic. I'm thinkin of a slight tilt like on a supra or even that 350z posted up.

How can I lower the sound without restricting the flow?

I originaly ordered the Greddy Ti-c muffler but its on back order. The next muffler that looked the same and was similar in price was the HKS. Everything else is really expensive.

I just hope its not a lot louder then my last setup. Id hate to rock the silencer. Imo it looks gay.

90% of aftermarket performance mufflers are a straight through design. The problem I see with using those Vibrant race mufflers as resonators is that they don't have much packing around them. You can tell the sound absorbing material used is minimal so they won't be doing much for reducing sound. The other killer is if you are totally cat-less and I am going to assume you are Tuko. I would keep the HKS muffler because they can sound down right sexy and they have a decent amount of high quality packing around the casing that won't break down like an ebay muffler and sound bad over time. I would however ditch the Vibrant race mufflers and go with something like an Aeroturbine resonator. From what I have read they do a much better job than any magnaflow resonator even though they are shorter. Plus you can see they difference in the casing and the amount of sound absorbing material used.

Aeroturbine resonator 3" in/3" out 26" long

The reason I chose to go with the vibrant is because they were cheaper then all others, stainless steel and they are mufflers. From what I understand mufflers are less restrictive and lower the tone better then resonators.

Its important that everything is stainless steel. I know its pricey but I might aswell get the best that I can.

Would it be possible to use the stock water heater and replace the factory piping with 3"? That's pretty free flow and would cut down your noise. Unless I'm just fantasizing trying to sound like I know what I'm talking about. Probably the latter.
