Which x-pipe to pair up with Vanguard Ti?

I am looking to add an x-pipe to my M and currently I am running on Vanguard Ti and love it very much. I wonder which x-pipe (without any modification; eg, cutting, welding) I should get if I hope not to get too much louder. ( i live in a townhome complex which 90% of the neighbours are retired(age-wise) and I don't want to put myself in the situation dealing w/ their complaints)

Any input would be appreciated. Thank you guys!!

I have the Fabspeed resonated xpipe and I am very happy with it. Check out my review here: http://www.m3post.com/forums/showthread.php?t=456387

I think I have a very quiet combination and probably one of the quietest you can get with a "full" system. Just keep in mind if you want a fully bolt on system without cutting/welding, you only have 2 choices:
1. Getting an xpipe (such as the Fabspeed) with the same company's high flow cat's. This is what I did. Unfortunately, this is usually quite a bit more expensive.
2. Getting an xpipe that has a cat-delete, which means the xpipe piping goes right from the header flange all the way to your Vanguard rear section exhaust. You willl cause a CEL light to come on because you do not have your primary cats. You will need some type of tune to remove it.

when i had my vanguard i did extensive research on xpipes.

i was wanting something that was performance oriented without crazy noise levels due to law enforcement.

I ended up deciding on the challenge x pipe..

but before I could pull the trigger i found a fantastic deal on a full akra system and got that instead

I don't think naming Xpipe manufacturers will help the OP. He's asking for specifics (not too loud and no cutting/welding). That cuts down on choices, plus even with the ones mentioned above there are downsides (CELs, aftermarket tune necessary, etc). You should provide feedback, reviews, etc. Why is Challenge great and Gintani FTW?

OP, to add to my post above...adding an xpipe to any exhaust significantly changes the sound. It will become significantly louder WHEN GOING SLOW, especially driving slowly through a neighborhood, and especially on a cold start. Unfortunately, that will pretty much be the only time you'll be in your development too. When actually moving/driving, the volume doesn't increase that much as the sound changes (throatier). The sound will depend on what cats you have (if any), what resonators you have (how many, and if you have any), etc. Your best bet is to try to meet up with another member who has a car with an Xpipe. Even the stock exhaust with an Xpipe is much louder.

I know challenge has a street version which will not cause CEL and doesn't require modification on OEM exhaust, but what about with Vanguard Ti?

Thank you Shamoo,

Nice review you have there! So the fabspeed with HFC will be one solution for me and probably be the best I am guessing?

You want power or just a bit more sound and slight more power?

If the latter then I would find one of the used x-pipes in the for sale section that have already been cut and welded onto an existing OEM x-pipe.

If you'd rather buy something brand new without cutting/welding then Gintani, Fabspeed, challenge are excellent choices.

If you go with any choice, make sure the x-pipe has at least 2 HFC's, and 2 resonators or 4 resonators

You have to see challenge x-pipes in person, they have awesome quality on their work and great sound with stock muffler not like empty can and not waste of $$$

I am satisfied with the noise and tone the Vanguard is making already. For the x-pipe, I am expecting to get some noticeable power gain; however, I doubt it can also be a quiet one as I wish for.

If I am not mistaken, the challenge street version will match with my Vanguard rear section without further modification. Correct me if I am wrong about this.

The challenge street, just like the fabspeed x pipe requires cutting the factory pipes after the primary cats.

I ran a fabspeed x pipe, with stock primary cats with my vanguard. I was really surprised, it made my almost inaudible Vanguard get pretty dang loud, and gave it a pretty strong drone at 2500 rpm. It was easy to drive around, since it was gone by 2250 rpm or 2750 rpm, but still a little annoying. Sounded absolutely fantastic, though.

The Akrapovic Evolution is significantly quieter.

Thanks for the clip! Did your customer mention having any drone compare to just the vanguard itself?

so the Gintani xpipe w/ HFC's can be bolted onto the Vangurad rear without cutting/welding?

Can you pm me the price shipped to 98281

Thank you

I wonder if level of loudness would have any change if it's with the HFC's?
