We've all come to agreement that taking the rear section off of a stock exhaust sounds pretty darm good.
Just don't try it with a Stillen exhaust. It sounds like CRAAAAAAP! http://i84.photobucket.com/albums/k3...nutt/003-1.jpg http://i84.photobucket.com/albums/k3...nutt/001-1.jpg http://i84.photobucket.com/albums/k3...nutt/002-1.jpg The Stillen rear exhaust section weighs 36.2 lbs! With the rear section removed, the sound is very raspy, similar to how a trombone amplifies the simple vibration of your lips..... the straight pipes (with resonators, headers and cats) amplify each exhaust pulse to make a cacaphony high pitch exhaust harmonics accentuated by a base line of BLAT, BLAT, BLAT! It does pull a nice 3rd gear scratch though. -Phim |

Dude I think that onboard sounds awesome... like a f'ing race car man. Not that I'd ever run that on the street but dude, sounds VERY MAD.

Phimosis, I think you need to take into account that you're running HFCs. Point being, I don't think it'd have sounded as raspy if you had the Stillen cat-back hooked up to stock cats, and then removed the rear section. That being said, I don't think it sounded all that bad. :tup: Giving you some rep for doing this little experiment, btw.

I had an 84 Mustang with no cats. when I installed the headers I ran it around the neighborhood with open exhaust. Sounded like a dragster. Pretty cool. I had a '98 4V Mustang Cobra with Kenne Belle supercharger. Ran it with HFC's and open exhaust. Sounded really mean. Way too loud, but awesome sound. With Borla exhaust on it, it was sweet street ride. Point being, I've had experience with other cars with low backpressure exhaust and have it sound great. I like the Stillen exhaust when it's all attached.... just a little quieter than what I like. I like a more racey sound. With that rear section off though, the sound is god awful. The camera microphone just doesnt quite catch how raspy and harsh the sound is. It's literally like someone is blowing a trombone right into you ears. It has so much BLAT, BLAT, BLAT that it reminds me of these guys that have 40's and 50's pickups with flat head V8's and 1.5" straight pipe coming from the headers with no Y pipe or H pipe to equal the pulses. I think a much racier sound can be found without the harsh acoustic qualities. One last thing is that there is no "cackle" on decel with the Stillen exhaust, but it does do it with the stock exhaust with rear section removed. It makes the stock exhaust with rear section removed very sexy sounding. |

I decided to remove the rear section of the muffler as well to see how the car sounded, stopped over at my buddies shop after work and I welded up a set of these to help direct the exhaust. Surprisingly the car sounds really great, zero rasp, very deep at idle and nice taper to a pretty tame upper rpm range. I am ordering up an exhaust tomorrow from a set of HFC and back. These will be available in private classified for anyone who wants to try them out.

I'm surprised no one has mentioned this but the 1st vid makes the 370z sound alot like a stock 350z. Slightly different but very similar, much more deep in tone.
|
I just did this muffler delete except i welded a pipe where the muffler goes. Sounds pretty good but i want to get rid of some of the drone or else ill put the stocker back on. Would resonators tame it out any????
|
def impressed by the sound from the muffler delete...sounds better than alot of full blown CB exhausts I have heard on this forum lol. Probably not much power to be had here but the weight savings + sound + $$$ makes for a decent DIY mod.
anyone thought of making turndowns bolted up right after the OEM cats? def pros and cons here |
im using custom turndowns right where the muffler bolted on until i can afford real exhaust. right after cats would probably be crazy loud?
