Another successful exhaust mod...

youdefinetly need X pipe sound will be much better and no popping.
but if you replace muflers too it will be little bit toooooo loud. either muflers or x pipe?! Muflers are louder option than x-pipe

[IMOLA 4.6is]

the popping I can deal with I guess

its the little loss of torque and raspy sound i feel is my biggest concern I want a deep v8 sound you know?

I guess you can say, I want the b&b or eisanmann exhaust sound without spending 1200-2500... Is this possible?

[dok47]

on my 3,0i engine I did get much better and deeper sound with X pipe than before and I was satisfied but I wanted to try make it even better and ordered muflers too. If i knew it will be too loud I would stick to X pipe. I am not sure about V8 but it should be deeper sound and I did not feel any loss of torque. Just give it try is not expensive and you can always take it off.
Let us know how it worked out for you

OK, I'll bite. So... an x pipe will sound deeper, offer a more efficient exhaust... maybe slightly better torque and is inexpensive to accomplish? Sounds like a no brainer! ...but I have also noticed that no one has mentioned the effect on fuel consumption...

I put a flowmaster on my GMC Yukon and absolutely loved the improvement to the sound of the vehicle, but the fuel economy went into the toilet. Before I was getting 17-19mpg... after the flowmaster and K&N install it went to 12-15mpg.... no noticable power or torque increases, but sounded mean and not too obnoxious.... I'm wondering if the x-pipe conversion on my 4.6is would have the same effect?


...what's the real impact on fuel consumption (before vs. after an x-pipe)?

Replace resonator with Magnaflow X-pipe. Leave the mufflers alone. I feel no loss of power or torque. I can post a before and after video if you want, but mine is 4.8is.

This is my next step.. I ordered the Magnaflow X-pipe today! thought I must say I LOVE the sound of the 4.8 with just the X pipe but from what I hear the 4.6 with just the X pipe does not sound anything like that due to the Valvetronic engine

4.6 is not valvetronic. 4.8 is.

4.6 M62
4.8 N62

[IMOLA 4.6is]

Correct, sorry, so vis versa from what I said... I talk to one guy one the forum who saw a video of a 4.8 on YouTube with magnaflow x-pipe put it on his 4.6is come to find out it is is didn't have anywhere close to the sound as the 4.8 bcos it was none valvetronic. Again this is from what I'm hearing

Magnaflow x-pipe will be at the shop tomorrow I hope it will solve the problem or else the stock resonator is going back on for now. Until I can afford a b&b or easinmann exhaust

Hey Imola 4.6... I also have a 4.6 and would like a fatter, deeper exhaust note, but not at the expense of torque or poor fuel economy... All posts seem to point to the x-pipe. I can hardly wait to hear some good news from you.
