Cracking Header
1 Attachment(s)
Hello All,
This is my first time posting but I've tried going through all the trends for help but have not found what I'm looking for. I have a supercharged BRZ and keep getting cracks in my header. First header was a Borla UEL which cracked once, I welded it and then cracked in another spot. I then cracked the stock header and then an Invidia header. I'm trying to find a better header that has a thicker gage wall, 304 or better stainless steel, TIG welded and back purged but its hard to find info on these headers without just buying and seeing the parts. Does anyone have recommendations on better headers or a way to prevent cracking? Side Note - I have added panels to protect my header from water but there is just as much airflow so the header can cool properly. I also have not used exhaust wrap. Any help would be greatly appreciated especially that I'm spending way too much on headers. |
This is what people get with inexpensive parts.
I am not mocking you BTW just stating a fact. Yes they are sub $700 headers but you have already had to buy 2 instead of 1 at the same cost I would recommend Tomei, JDL, ACE, Nameless they are a quality part |
How are your EGTs?
|
celek - Ill definately take a look at the brands you suggested.
CSG Mike - I have not tried measuring the temps. |
Out of curiosity what are the engine mods?
Is it just a lot of track time because cracking three headers including OE is insane, even if you can blame the quality of the aftermarket headers, cracking the OE ones is rare but not unheard of if tracked and with FI. |
Spend better money on a tune, then work on fixing any header problems.
|
JDL are known for having thicker metal which incidentally makes it a tad quieter. Also what kind of supercharger are you using? I was Edelbrock supercharged and never had an issue for 6 months (before i took off the SC). my friend is JRSC boosted and he cracked his OEM header, but that was after a full year of track days

Hello All,
Sorry I have been busy today and haven't been very responsive. Engine Mods have just been adding a Edelbrock E Force supercharger with the standard pulley. The tune was custom and done by P Tuning without flashing and was not cheap. I saw all the setting and charts and no issues there. I decided to buy a Tomei and a JDL to see which has better welds and material thickness. Thank you all for the help. Let me know if you have other suggestions to prevent cracking. |
When you say was not cheap sounds you was ripped of
|
I have all the data from the tune so what should I see wrong that would cause header cracking? I'm asking so that if they screwed up I can go back and have it fixed.
|
Would LOVE to hear how you "tuned" the car without flashing.
|
Sorry should have said we didnt just flash a premade tune.
|
Surprised you have a heating issue with the Edelbrock. that kit is known for its incredible heat managment. Methinks the tune might be the issue. While you might have been tuned for best performance...that . might have come at a cost
|
What's the best way to adjust the tune for lower exhaust temp? Running rich, lower compression?
