I have an 01 V6 and am looking to upgrade to a true dual exhaust. I plan on a mid-pipe and cat back, but cant decide what to get. Which pipe( X or H) is better for a V6? I have heard that this combo is good for power and sound, but I have also heard that these pipes and a cat-back will sound like a 4 on steroids or your average ricer, which is no good. What is the best combo for power and sound?

 

I don't think 6'ers need an X because the pistons fire evenly or something like that...so get an H pipe for a 6'er....and I'm still trying to figure the rest out myself.

 

oh okay, thanks. I was probly gonna go with the MAC catted H, then on to some kind of Cat-back...so many choices....whats the deal with the intake silencer? What does removing it do for performance?

 

You dont need a x or h. you can run straight pipes and recieve the same hp gains. It is debatable that the x and h even change sound.
Also are cars never sound anything like a 4 bang because of the displacement and the extra cylinders. The even firing order will give it a some what higher pitched sound, but it is more comparable to a ferrari.

 

hmm. So are you talking like the V6 dual adaptor or a straight bolt-on to my stock Y-pipe?

 

Cut the y and have them run straight pipes from your cats to your mufflers( no crossover) or you can get a crossover some say it changes the high pitched sound. Do what you want be different in any way possible.

 

So you're saying crossovers make it deeper, or higher pitched?


6er, if you do a straight bolt on to the Y pipe, you won't be gaining and performance, or much of a better sound, that's mostly for looks I guess you could say. Just cut the Y pipe out, and weld in 2 pipes going straight to the dual catbacks, which will give it more flow and better sound. Or if you want to spend extra money, go for an H pipe.

The intake silencer is a rubber-funnel shaped object that connects to the only opening to your intake system, and the funnel's smallest point is where it brings the air in, it sits in the area behind your right headlight and the opening faces the rear of the car. Imagine breathing with your mouth open, and notice how easy it is...then put a straw in your mouth, and try breathing through that. That's basically what the air silencer is doing - making your car breathe through a straw. Once you take it out, alot more air will getting to the intake alot faster and will give you a slight boost in rpm's and a better sound to your car when accelerating (It varies for people, some don't notice a change, some do. I did, but it's something you should do regardless.

It is very easy to take out, there is a guide for it somewhere...let me find it.

edit: here's the link http://www.mustangworld.com/ourpics/fcar/intke.htm Takes about 5 minutes to do

 

you need that crossover....thats what i have been told many a time...it equals out the back pressure i believe...

PCola: h pipes make the car sound deeper...x pipes make the sound high pitched

 

Ok, thanks for the info

 

I should really creat a v6 exhaust sticky here...

YOU DO NOT NEED A CROSS OVER ON A 3.8 V6!!!!!!!!!!!!!!!!!!!!!!

We have even firing engines unlike our v8 brothers. Therefore a crossover is not necessary if you get it all it will do is change the sound it will do nothing positive for your back pressure...

 

But it does make it sound deeper, right? (h pipe)

 

I wouldn't say deeper...Um less raspy I guess is a good way to put it. I have straight pipes and it sounds good to me. Stock GT mufflers right now so it's quiet at part throttle and at wot it starts to wake up I kinda like it like that. But I've heard straight pipes with like macs and it's raspy.

 

So H pipe with MACs would be less raspy then straight pipes /w MACs, true?

 

yes not deeper just less raspy lol.

 

Oh okay, I guess it's worth the 180$ to make it sound less like a rice burner,heh

 

the H-pipe gives you more of that "blub blub" drag car sound, as opposed to the X pipe thats more that F1/racecar sound (aka raspy)

 

On my old '02 v6 I did a custom 2 1/2" o/r X-pipe with 2 1/2" pipe all the way back through 2 40-series deltaflows and it sounded great. I got plenty of complement on it everywhere and 90% of the people who asked about the exhaust thaught mine was a v8. We dynoed a '04 v6 with the "Y" cut out to make straights and MAC mufflers....also had an intake...he made 13hp less than mine with a stock intake and just the exhaust. Well the kid went and baught the same X-pipe from the guy who did mine...his HP was even with mine the next go on the dyno.

 

there is an exhaust sticky its all there for those to read.

 

soooo. tentatively, I am thinking a MAC Catted H......i dont know about custom straight pipes really. So unless it really is worth it, such an H pipe and a nice catback would be a good set up for power and a deeper sound(for a V6)? Also thanks for all the talk so far guys.

 

i think mac h and GT take off catback is a great combo not to loud and flows alot better.

 

Thanks for the info. I may just do that.

 

yea...just get the mac h pipe...catted or uncatted...and get a catback of your choice

 

VA ehh? wait so r u saying you mid pipe got you 13 hp? if thats true point me in the dirrection of your exhaust guy cuz I might wana drive down there...how much was the custom fab?

 

How does anyone feel about catbacks from a MAC H-pipe? Thinking magnaflow magnapack catback or the MAC one....

 

Once I get some more un-needed cash I'm going to go with the V6 MAC H pipe and GT MAC catback..so if you don't get yours before me I'll tell you how I feel.

 

try the magnapacks...lol i have them and want to know what they sound like with an o/r h

 

sounds good. It'll be a LONG time before I get some cash too, so good luck with your set-up. Are you changing to a GT fascia too?

 

I'm probably just going to lower the tips at first, GT rear bumper isn't very high on the list....gonna be near 500 somethin with paint. =|

 

I would go with a chambered muffler to help the v6 keep a deep muscle sound. But thats just me.

And for the love of god dont get flowmasters. Or you can sound like every other truck and airboat out there.

 

how about slp loudmouth I???
