hi there mustang community ,

i have a mustang 2005 GT Coupe in Torch Red.

im just gonna get to the point , instead of going with axle-backs i would like to keep my stock mufflers and get an X-Pipe , Bassani maybe.

What do you think of that in terms of performance and most importantly SOUND , i want to keep my mufflers looking stock but i want a more deeper sound. Do you think an X-Pipe will do that? and what's the difference between a X , H-pipe ?

i wanna hear your thought about this ,

thanks y'all.

The H-Pipe will get your deeper tone!!! I changed to the bassani x-pipe and comp cats and it made it much higher pitched!!! I hear the prochamber from MAC will give you the deepest, I been debating to change to that but haven't heard any stories on it... anybody????

I had the UPR off-road X-pipe on for about 6 days,(until my CEL came on:sosad: ) it was loud with the stock mufflers. It was nice and deep. I liked it very much. The additional torque was nice too. I got alot of vibration/harshness from the front, where the actual pipe was. This pipe was aluminized steel, and not stainless steel. Could the pipe material control noise? Thanx

2k5stang , was that before the MAC Mufflers ?

hogpower , i really don't know about the vibration , i hope that doesn't happen with me, or maybe there was something wrong with the installation, you should get it checked out.

guys do you know where i could find a sound clip of a mustang running a x-pipe with stock mufflers ? hogpower could you record yours ?(maybe im asking too much) :D

thank you all for your replies

I just got Kooks headers on with a catted X, sound is awesome! Unfortionately it is a higher pitch due to the X... But it sounds TRUE POWER! High quick revs, you feel the exhaust moving under your car at start up. No drone! Awesome power gain, TQ is even better! http://www.modulardepot.com/product_info.php?products_id=229 That's a special and AFM members get some more off...

If that's too pricy I'd go with the MAC chamber... if you're out for tone and some power (TQ). Danielle at MD has it, it sounds MEAN! She has pretty open muffs too though... but I think she's kinda keen on my Kooks system...

X have some power as well but a bit quicker pitch... more power, less 70's straigh pipe V8...

H for tone.

H-pipes, in general, aren't as free-flowing as x-pipes. But I do have a question for you stang... Why do you want to add an x-pipe, but eep your mufflers stock? Your HP and TQ gains will be virtually none with just a pipe. If you want a more tuned, aggressive sound, change your muffs. You'll just be creating a bottleneck in your exhaust if you change your pipe w/o changing your muffs. But to answer your question, I would go w/ an x-pipe. I have the off-road Bassani. Check that out...it's pretty good.

At near stock levels, the OEM mufflers are hard to beat. The performance gain from an X pipe is in the tuning of the exhuast pulses. The X Vs H pipe is rather muddied and the placement of the H is more critical than the X pipe. All the shops I've dealt with agree that the X pipe has a slight edge in performance and can actually remove some resonant vibrations in the exhuast pipe.

When I change my exhaust system I will probably keep the stock muffs, unless I'm gonna spend the extra dough on a different "look". From what I have read the only real opportunity for the exhaust lies in the stock shorties. What are replacing the stock muffs worth; 1 RWHP?

Yea, there is not much power in the 2nd half of the exhaust system... My RWHP gain guestimates are:

LT Off-road Headers with X ~24 (H ~22)
LT catted Headers with X ~18 (H ~15)
Other headers less than above gains...
Off-Road x-pipe ~9
Catted x-pipe ~5
Mufflers up to 3 HP in combo with one of the above, 0 with the rest stock...

I'd love to see/hear LT headers X to stock muffs, why not? Don't think there is much loss, sleeper look but more sound, at revs! Allmost as much power as a tuned CAI!

Here is my new 'first mods list':
Tuner (SCT)
CAI (Tunable Inductions)
LT Headers (Kooks)

All can be had for less than $2K!!! And will take you to and break the 300 RWHP level!!! It will run, drive and sound awesome!

KJ - Don't forget about the Charge Motion Delete plates for ~$250 that will give you an extra 10HP. Best bang for the buck after CAI/Tune and gives even more power with the headers. This would get you over the 300HP mark BEFORE plopping down $1400+ for a header set-up.

That would be next with UD Pulleys for the same amount... Those two can be a pain for the do-it-at-home-guy though... So might the headers... I changed my mind regarding moving the headers up on the list after feeling and hearing them, oh whatta nice mod!

I honestly don't believe CMDP's give 10 or more, nor the Pulleys, mind you I have both and think it was not at all what I expected, was hoping for, while the headers was way more!!

More guestimates:

CAI+CMDPs+Pulleys+Tune $1,100 (install ~500) hight 30's gain
CAI+Headers+Tune $1,800 (install ~400) high 40's gain + THE SOUND!!!

well i wanna keep the stock mufflers because im going for the sleeper look + im propably gonna put a body kit real soon so my mufflers will not be showing anyway.

so you all agree that the X-pipe is better , it's not too loud is it ? i don't want to get in trouble :D if it's too loud .

and whats the difference between the offroad and the regular one , is it the cats ?

i think im gonna go with the bassani's ..

I would do the same if I did it over... keep the stock muffs that is...

The X pipe is better for power, it is a bit louder at high RPM but not much, idling and low RPM it's the same but a bit quicker more race inspired....

You got it right, off-road is missing the cats, making for more power, quite a bit louder, and a federal offence... :rolleyes:

I had the Bassani X and liked the sound and the little power it gave... but as you see above I re-thought the whole thing and am very happy I did... It sounds like you wanna do some stuff to your car and I would in a heart beat recommend spending those first 2K as mentioned above, CAI, LT Headers with an X pipe, and a tuner! Cats is up to you... It is all avail from MD and you'll get one of the best tuners in the world doing your tune (all set up, plug and play for these parts!) for free by buying it there!

I had the MAC Mufflers for a while then I got the x-pipe with comp cats from bassani... Honestly it doesn't sound good in the car but not to bad outside the car. It's a high pitched in the high revs but low rumble at idle. Lots of muffler drone too...

My experience is that the cats muffle more than the mufflers do.

WARNING!!! WARNING!!! I don't know what your plans are, but I can say this: Do NOT install an off-road X-pipe (Bassani) with SLP Loudmouths. After reading a recent MM&FF article about the supposed effects of installing an X-pipe (December issue), I ordered an off-road pipe and put it in with my SLP's to increase flow and eliminate that 1/2 tone BLAT (read the article). But I had no idea just how much catylitic converters muffle the sound of an engine, and when I fired up the engine for the first time after installing the pipes, I nearly sh*t myself. Not only was it embarrasingly loud, but it sounded like a roid-raged Sumo wrestler slamming two gongs together at the speed of light. Friggin terrible. I took it out the next day and put the stock H-pipe back in. I would suggest some research before deciding what to buy. And I would definitely not recomend a non-cat-SLP combination.

I went with JBA LT to offroad H, and the JBA axleback, after listening to their example on the website. It has a nice deep tone. As stated earlier, the X will give you more power, and a higher note out back, while the H will be slightly less power at a much lower tone. It's all a matter of opinion, unfortunately it's difficult to decide without seeing/hearing in person. I'll see if I can't get a video/sound clip later this afternoon for ya...

thanks guys , as i stated in my original post , im thinking of getting the X-Pipe only with stock mufflers , i just want it a bit louder.

ChestyP79 , actually i heared that clip of that combination it was awful, but the guy put on the Bassani axleback later on and it sounds awesome.
cccole, that would be great ... im waiting for your clip.

thank you all for your comments ,
