I had a theory a few months ago about v6 exhaust. If you've read the exhaust sticky at the top of this forum then you know that the v6 is an even firing motor which prevents it from be able to obtain the uneven rumble effect of a v8. Well, what if you offset your mufflers,glasspack or whatever you have, meaning that the mufflers aren't lined up evenly so that the exhaust gases enter and exit the mufflers at different intervals creating the rumbling effect of a v8. I know for the most part the space in front of the rear axle of the 94-04 models where the mufflers fit wouldn't allow for enough space for an offset alignment but glasspacks are small enough that you don't have to fit them in that space for fear of a lower ground clearance.
I've had 4 different exhaust setups on my 04 v6 to include, dual magnaflows w/3 1/2 in. tips, dual flowmaster 40s w/ 3 in. tips and 12 in. glasspacks w/3 in tips then with no tips at all. I wasn't satisfied with any of those setups, my favorite being the magnaflows. But I put my theory to test by cutting everything off and started fresh with dual pipes 2 1/2 in. in diameter and cut one side 3 inches shorter(anything less than a 3 in. alignment offset probably wouldn't make a difference) than the other side, both sides being cut short of the rear axles to be hidden. I found that this created a noticable rumble, not to be compared to a v8 mind you, but it was definitly present. While excelerating it sounds very similar to an old school v8 car or truck that's used for weekend drag racing and its not so loud that you would get a ticket
but I guess that depends on where you live. I personally like it myself. I know it may not be an attractive sound to many of you but to each his own right.
But the next time you have new mufflers welded on keep
this offset theory in mind, if you're willing to try it, and let us know if you can tell a difference. It may not work for all v6's and I'm sure it won't be practical for all dual exhaust setups but if you like to experiment with different sounds like me then give it shot and see what you think. If you're about to install
a new exhaust setup then you can cut the pipes like I did, one shorter than the other without mufflers, then take it for a spin and see what you think.
Then of course if you don't like it then you can go on
with your
original plans without cutting off an already existing exhaust system like I did. Pretty dumb, I know, but in the interest of experimenting I think it was worth it to see if my theory made sense and I personally liked the outcome. If you think this is B/S then don't try it but please don't waste your time telling me your negative opinions. Just ignore this and go on about your day. But If you do try it out of curiousity then share your thoughts with everybody because I can't afford to go through any more exhaust setups trying to justify this theory.

 

this is interesting to me. it does make sense... I have a v6, all i did was put a flow 40 on it and left everything else alone.. i have a CAI.. I think its the best sound ever! did u ever try a single before u went double? If so do u like duals sound alot better? basically whats the difference in the sound? I like how mine sounds, i wish it could be a tad louder tho..

 

Cool idea, but its not going to make it have the v8 sound.

 

Don't get me wrong here. The idea behind this theory is not that it will make a V6 sound like a V8. The point is to give a v6 that uneven loping rumble effect of a v8. We all know by now a 6 can't be an 8 so don't think this is a v6 owners desperate attempt to match the sound of the GTs. Again, because the v6 is an even firing motor, by offsetting the alignment of your mufflers then the exhaust gases would enter and exit at uneven intervals allowing the rumbling uneven effect to take place. Remember this is only a theory and it hasn't been tested enough for anyone to know if it is does actually work or not but I personally tested it on my v6 and found it to be true. But that was with no mufflers,only straight pipes cut in unequal lengths between the cats and the rear axle. I haven't ever tested this with X or H pipes or with any brand of mufflers. The 4 exhaust setups I previously mentioned were all done without an X or H pipe and were not offset like they would've been if they were part of the testing. I only recently thought of this and wanted to get people thoughts on it if anyone were willing to try it.

 

Your v6 will never sound like a v8, but if you want your v6 to sound a bit like a v8, try getting MAC Long Tubes, a MAC H-pipe, and a MAC Catback, it will be as close to sounding like a v8 as you can get, oh and btw i know this because i had three setups on my v6. Having a nasty cam will help too. Sadly i dont have any sound clips for you to checkout.

 

i found some setups like that. and jeez they do sound close, but only thing is when u get in high rpms it dont, but at idle its identical,, i want to do that setup soo bad. theres soundclips on youtube. i typed loud mustang v6 exhaust long tubes in the thingy and it was a silver mustang, if u all cant find it i will. it sounds good, but hes not going for the loudness n stuff, hes trying to get a loping sound they make becuz v6's are even firing, and by having one side shorter then its gonna come out earlier and kinda blend, its hard to explain.

 

I like this idea. I've never heard of this being done before but I would really like to try it.
