Greddy evolution catback

[shouldbeasy]

That section wont move as long as you lossen the bolts. It can always be re centered 😉

Having the exhaust tip that close to the bumper scares me - I actually burned my leg (two half circles!) on my Borla tip so I know it gets silly hot - not something I want in contact with plastic!

Yours seems set up nicely - good finger plus width in between tip and bumper.

Thank my GF. She made sure it was nice and center while i was under it adjusting.

I wouldn't want it any closer to the bumper...

I was talking about the mid pipe,and I hear you on the tip but it has enough gap to not touch the bumper.

 

[PunkST]

^ lol my tip was hot. Bumper was cold to touch. If i think its gonna be an issue ill use some of my gold foil tape and cover the area to keep it from melting.

Put rubbers on the back end for the muffler. Itll get a lot quieter. The poly sends a frequency through the trunk floor and turns the hatch into a speakerbox of sorts.

I am thinking of just swapping all the hangers back to stock.

 

[PunkST]

I only habe the one poly in the middle. I need a stocker to replace it later. But its soooo much nicer

 

[Negi]

Yeah Dude I am feeling the vibration lol

 

[PunkST]

Hahaha. Maybe im getting to old. But my car shouldnt feel like im re entring the atmosphere 😂😂

 

[Negi]

Long ish story short. I wasnt happy with my CPE nexus i picked up used. So i managed to sell it and promised myself to get a different setup. Ill get better pics tomorrow as i still have to put my midbrace back on.

Things i learned
1. Bad gaskets by the downpipe can make really big and loud bangs. So far the new setup hasnt.
2. If your stock DP get rons adapter to upsize or go to oreillys and try to find a gasket that will work. I lucked out after selling the adapter with the catback and then kicking myself. Lol. ( i have a catless DP waiting for an install day at a shop soon)
3. 2 bolt flange is much better than slip fit for being able to assemble and adjust. Esp, when its 18 degrees under the car.
4. 700 degree copper gasket maker is your friend. Use liberally on the gaskets and let it fully cure (24 hours of car on stands looking like a ghetto wrc pit area)
5. Polyurethane exhaust hangers are the DEVIL. Never again. Id rather break rubber ones constantly and easily replace them than have to literally cut them apart to get the old exhaust off the car.


Impressions of the catback.....
Amazing welding. Easy to fit together, love that they include enough bolts to even replace the studs on the downpipe if needed.
The fit is perfect. Minor adjustment at the joints to get things centered. But nothing hit the tunnel ( unlike the resonator on the CPE that hit the tunnel constantly) it is 304 stainless and the flanges have greddy cast into them which i thought was super cool.

Driving.
So far havent driven it much. But i love the sound at idle, which is super deep and mellow. Getting on it i can hear lots more of the turbo and engine which is a huge plus. Im sure my neighbors prefer the car being a fair bit quieter. Hoping to see my gas milage go back up. Im curious to see how it sounds with the catless DP. But im extremely happy with the exhaust despite my frustrations with weather and old parts not wanting to come off. Made a 4 hour install take over 8 hours with a lunch and parts break.

How is the drone? I can't find much information on this exhaust system.

This is my fav exhaust. I’m just waiting to hear it in person. Unless the upcoming whoosh catback is flanged I’ll be going Greddy.

Its mellow. Not buzzy like the MBRP or anything like that. It still exists, but its just not as bad. I don't mind long highway trips.

 

[PunkST]

Its very mellow. If you use rubber hangers. Its perfect.

 

[Negi]

I agree with PunkST,I had poly mounts when i first installed it and it was bad lol,Took it out in less then a month and put the Oem ones back and its so much better plus it hangs a little lower now and i am not worried about melting my Bumper lol

I got the whoosh extended ones and its perfect.

 

[Negi]

i had whoosh too,but the xtra vibration was too much for my Old ass lol,i mean the gap was close but was not touching the bumper

Its unfortunate you don't like the poly hangers. I love my poly hangers, I don't like my exhaust flopping around like a dildo.

You can tell this is a top quality GReddy product by those welds

One thing is for sure - you need a stiffer dildo.

I installed the Greddy exhaust over the weekend and so far I'm not liking how it sounds, especially on decel.

I get a crazy amount of bass from the exhaust inside the car to the point where that's all I hear. I've gone threw a few overpasses and tunnels and I can't make out how it sounds outside of the car because the sound inside is so deep.

I installed it with the stock downpipe and Ron's 2.5 to 3" adapter with the stock hangers. Everything is tucked up and centered in the exhaust tunnel with no contact to the body.

I really want to like this exhaust because it's beautiful and the build quality is excellent but it really wears you down when you drive an hour to work.

I'm kind of at a loss with this. Is is possible I installed something incorrectly? Would an exhaust leak cause that sound?
