Looking to buy an catback for my 2010 lnf. And I was trying to figure out the best sounding / best performance 3in out there. it need to have an can on it , no straight pipe.

 

remove muffler

 

Zzp never fails.

 

I have the turboxs FL cat and love it

 

I have MPX's with a 3" Magnaflow. It sounds good but isn't ridiculously loud like when I had no muffler.

 

Stock till what 350 HP?

 

Can you guys post videos of your exhaust. I am in the same predicament

 

I am in the same boat, looking to go with an aftermarket exhaust finally. I was leaning towards a ZZP hi-flo catted DP (looking to avoid CEL and inspection problems in NY) and either ZZP catback or MPx Catback. Anyone have either of these combinations, any thoughts?

Thanks

 

Factory exhaust is pretty free flowing so I hope you don't think it's going to net you much hp. I have a full mpx cat back and love it.

 

I'm keeping the stock exhaust piping. Cutting off the muffler and dojng a Moroso spiral flow. .

 

you guys could easily google search this question and get many videos with sound.

 

You could easily provide links

 

my car, mods are in description

 

that zzp one sound sick, to bad the tip sticks to far out in the back which I hate.

 

it does, and you must find a longer rubber insulator for the muffler or it WILL touch the bumper and burn it. pretty easy fix though

 

Honestly, I just did a muffler delete and welded a pipe in. I've gotten a ton of comments on how good it sounds. Cost me $40. Is there a law that says you need to have a muffler or something?

 

that would depend on were you are, some places will have decibel level limits but they are always different shades of grey. look up the local laws in your county/state

 

Quiet exhaust, loud turbo/supercharger. Done. Tired of the days of 4cyl exhaust sounds. Attracts all the wrong attention as well. Change the header or DP of course, for the gains.

You will never get a proper impression over video's. Need to hear it in person.

 

That's why I am doing a spiral flow

 

I want to here the stock resonator replaced with this

 

I run a catless Hahn dp with the full Hahn exhaust and it sounds great not very loud until you get on it but easily livable for DDing and it can be heard when romped on

 

this is my Borla on my n/a 2.2 and I think it sounds good.

 

They don't send it with one?

 

ive had all 3 of these at one point. the gt exhaust i had first and then i had tried the other 2 out before they were even released. i love all 3 of these exhaust best ones for an lnf in my eyes

And they don't include this rubber isolator?
