FLlegacy Posted October 24, 2018 Share Posted October 24, 2018 I have a spare as well, Without wideband O2 bung, though. Link to comment Share on other sites More sharing options...
FLlegacy Posted October 24, 2018 Share Posted October 24, 2018 Is that core wastegate still going around? i thought there was another thread for it but I cant find it and someone is interested in getting the wastegate to port for their 5th gen. I have the housing core, unfortunately is has a wastegate crack and noone wants to touch it now. I haven't done anything with it because I don't have any issues with mine and I am not looking at any more mods until maybe late next year.

A_A_ron Posted October 24, 2018 Share Posted October 24, 2018 Who wants to sell me one? These work with stock turbo right? Is it a high flow cat? Can I put in a second upstream AFR O2 sensor bung hole? Build Thread Link to comment Share on other sites More sharing options...
ChrisCrash Posted October 24, 2018 Share Posted October 24, 2018 I'd sell mine for 500. Link to comment Share on other sites More sharing options...

Can I put in a second upstream AFR O2 sensor bung hole?They do work with the stock turbo, and have a 200 cell high flow cat, but you'll need to port your wastegate to use it effectively and avoid the boost creep. I'd sell the brand new one for $500. Comes with intermediate pipe.

FLlegacy Posted October 24, 2018 Share Posted October 24, 2018 Who wants to sell me one? These work with stock turbo right? Is it a high flow cat? Can I put in a second upstream AFR O2 sensor bung hole? I'd sell the one I have, Jpipe only, for considerably less than $500. The boost creep seems to be an issue with hi-flow cat-back systems. I have the stock exhaust with no creep or overboost issues since installation. That seems to be the only difference between my car and the other installs. Porting the turbo, I would recommend either way to have more headroom in case you do want to go with a noisier exhaust or already have on. If you have the turbo off anyway and the time/ability might as well do it. Link to comment Share on other sites More sharing options...
spb Posted October 24, 2018 Share Posted October 24, 2018 How well do these work with a stock exhaust? Do they still make car louder? Link to comment Share on other sites More sharing options...
Sarang Posted October 24, 2018 Share Posted October 24, 2018 Yeah slightly louder, and slightly more raw sounding. Not much of an increase in noise though. Link to comment Share on other sites More sharing options...
Shadow_419 Posted October 24, 2018 Share Posted October 24, 2018 How well do these work with a stock exhaust? Do they still make car louder? I don't know how much louder the Nameless is over the AVO j pipe, but I can definitely hear it when I get on the throttle. It's definitely not "l have an exhaust" loud but it's noticeable inside the car so I imagine outside as well. Link to comment Share on other sites More sharing options...
FLlegacy Posted October 24, 2018 Share Posted October 24, 2018 Slightly louder, but if you didnt know any different you would think it was stock for a turbo ej25. Sent from my SM-G965U using Tapatalk Link to comment Share on other sites More sharing options...

11boostedgt Posted October 25, 2018 Share Posted October 25, 2018 Sooo I have spent some time reading all through here about boost creep with the nameless high flow cat j pipe. Was just wondering if ppl have the same issues with a catless one? Let’s say like a invidia jpipe? Really don’t want to deal with all the boost creep issues if I don’t have too. And have no problem going catless if they still work good Link to comment Share on other sites More sharing options...

And have no problem going catless if they still work good If you read through enough posts you will notice, there is no real trend, except inconsistency in this regard. Some people have boost creep, others do not. The best thing you can do is port your waste-gate or leave the stock Y-pipe and mufflers on IMO. It may really be down to casting irregularities in the turbine housing itself, which is very likely. Local weather, tuning, and driving habits will also play a part. Either way, the issue with boost creep seems to be too little back pressure, and/or not enough waste-gate flow. There are ways to combat either issue, a catted Jpipe and stock cat-back are just one way. Link to comment Share on other sites More sharing options...

GTEASER Posted October 25, 2018 Share Posted October 25, 2018 Most everyone with a 5th Gen GT who went with the Invidia catless has had boost creep issues on the stock turbo. Going to an 18g or 20g with a larger turbine seems to mitigate most of that issue both with and without a cat.

Headache Posted June 6, 2019 Share Posted June 6, 2019 Hey guys, has anybody installed the Invida catless j-pipe on their legacy? I just installed mine yesterday. I have a nameless midpipe (straight-pipe) followed by their y-pipe ending with dual nameless muffler deletes. I am having the most annoying rattling sound during downshifts from the J-pipe contacting the car's unibody. I thought the bracket that bolts to the turbo manifold was the cause of this and after installing the bracket, I realized the rubbing has gotten MUCH worse. During idle I can feel the exhaust rattling. Took the bracket off and the rattling has gotten slightly better yet, is still pretty bad. I've checked my engine mounts and they appear to be in good condition. I am having trouble reaching Invidia at the moment for possibly a return on a defective pipe. I am very close to swapping out for the stock dp because I am worried the added stress and minimal clearance of the new pipes is going to cause my turbo to come loose and eventually results in another engine rebuild. Would really appreciate some feedback here. Link to comment Share on other sites More sharing options...
Sarang Posted June 6, 2019 Share Posted June 6, 2019 Can you post a picture of where it's contacting? My Nameless DP isn't close to the body, so I'm having trouble picturing what you mean. Link to comment Share on other sites More sharing options...
