Has anybody just taken the muffler off and extended pipes out to the tips?

Looks to me like it's virtually a true dual system just as it stands except for the one muffler.
It has what amounts to a X-pipe for mixing, then goes separately into two resonators.

I dropped the pipes off the muffler just to see what it sounds like, and it doesn't sound bad at all at a standstill and revving it a few times.

Does anybody think or know if there might be adverse tuning effects?

Thanks-

 

I had done it. Still have the 2 extension pieces. It will open up the flow which is great. But when you get on it WOT it is LOUD. Sounds incredible though. But living in Cali the cops are d1cks about stuff like that, so I took it off. Sounded really good though just load.

 

G35 robby has this on his sedan paired with ingens. Sounded amazing but he changed it up to an invidia I think.

 

Thanks-

What about performance?
Were you able to notice any "seat of the pants" difference in performance or did you run some 0-60 times before and after?

Sound is one thing, but just to make it louder, and not have any gain is something I won't do.

 

wow your hacking up the G already, that sounds like ****.

 

Hacking?
I've done absolutely nothing, yet, and quite likely won't mess with the exhaust at all.

I'm asking questions.

Explain your comment-

 

This is a 40k plus car and your asking about taking the muffler out and running straight pipes, I think my comment is quite expanatory in itself if you ask me...

 

I was thinking about doing a resonator delete as well. I love the stock exhaust sound, but I'd like it louder.



EDIT: I just read that back in my head and it sounds soooo ricey. Forget that. LOL

 

Do a search on youtube, there is a guy that did it and it sounds like crap

 

After mixing coming from the manifolds, the coupe exhaust separates and runs through two bullet type resonators/mufflers before each separate pipe heads into a smaller single muffler at the back.
Straight pipes??

Dropping the bolted connections off where both pipes enter the muffler didn't sound any louder than my FX. Of course, that wasn't under load, and that was my question. Had anybody ever done it, and were there tuning issues.

I was complimented everywhere I went for my FX exhaust system and it picked me up about .3 of a second in a 0-60 time. (Of course, I did the Stillen air intake at the same time, so a combination of both resulted in that particular gain.) I shaved another .3-.4 off with further bolt ons after that making it one of the fastest NA FX35's to be found anywhere.

I may well do nothing to this vehicle, except add a strut bar as I intend to autocross it and get it to the track, too---just like my FX
The Coupe exhaust sounds pretty damn good just the way it is.

Once again, certainly not "hacking."

For your edification:
The definition of hacking is:
1. to cut, notch, slice, chop, or sever (something) with or as with heavy, irregular blows (often fol. by up or down): to hack meat; to hack down trees.

Come on now.......

 

To tell the truth as soon as I got home I took it off and put the stock muffler back on. The sound was TOO loud for me. It was like being at a stock car race. So for performance I have no idea. The sound was great, just not enough refinement for that type of car. That type of setup would be great with a bypass valve. Quiet when you need it, loud when you want it.
And really, unless you get at least an intake AND a tune your only going to really be changing the sound if you change your exhaust alone.
