sumfoo1 Posted May 25, 2011 Share Posted May 25, 2011 From what I've heard so far from my tuner, stay stock, or get full-race everything else cracks. I want to verify that on here if possible. Thank you, Foo1 Link to comment Share on other sites More sharing options...
BAC5.2 Posted May 25, 2011 Share Posted May 25, 2011 I've had good experiences with GT-Spec, but I'm probably going to use a set of TurboXS headers.

TRSCobra Posted May 25, 2011 Share Posted May 25, 2011 Besides slip joint leaks, I've heard good things about Perrins. I got them for their smaller primaries, been running them for 11k miles or so with no cracks. Just had the leaking slip joints welded, so who knows how long they'll last now. But I did start a thread on nasioc asking who had their welded perrins crack and got several responses of good experiences, no reports of cracks.

m sprank Posted May 25, 2011 Share Posted May 25, 2011 All headers will eventually crack. Physics. That being said, good brands last longer and have better warranties. Perrin-expensive and warranty void if wrapped or coated. Also poor workmanship. GTSpec/Tomei- great price. warranty good if wrapped or coated. extreme qualty control. comes with very nice uppipe. Borla-lets not go there AP- I feel like they are in the Perrin range. AVO- can you say overpriced? KillerB-very nice if you got $1500 FullRace- best out there. also $2000+ Link to comment Share on other sites More sharing options...
kb2spn Posted May 27, 2011 Share Posted May 27, 2011 20000 miles on an un-wrap gt-spec.....no cracks. Link to comment Share on other sites More sharing options...
Balrock Posted May 27, 2011 Share Posted May 27, 2011 I have had my GT Spec for 3 years and no problems. I had them thermal coated by Crucial and I also wrapped them. Same for the UP as well. No complaints at all. Link to comment Share on other sites More sharing options...
m sprank Posted May 27, 2011 Share Posted May 27, 2011 Good to know. I really like the GT-Spec. Knowing that members have them long term with no cracking (so far) is good info. When you see them up close, the welds are almost works of art. Obviously a lot of machine welding. They also port match the pipes and add a velocity stack to the up pipe. Very nice touches. The foam formed flanges are really nice, and I prefer the three bolt up pipe flange. Better seal. Did I mention that they come with about $60 worth of high quality gaskets too? Gaskets you can actually use. Link to comment Share on other sites More sharing options...

m sprank Posted May 29, 2011 Share Posted May 29, 2011 Which design? They have a few now. Overpriced is my opinion. Link to comment Share on other sites More sharing options...
sumfoo1 Posted May 29, 2011 Author Share Posted May 29, 2011 I've read that the large tube el ones delayed spool by 3-400 rpm on a 30r sized turbo. And the 2" primary Amr ones were even worse. Link to comment Share on other sites More sharing options...
m sprank Posted May 29, 2011 Share Posted May 29, 2011 Large tube means FullRace. Read between the lines. When you have a 500+whp car no one cares about spool. 4000rpm hit is normal. Motors are built and produce more low end grunt, so spool is not an issue. Entirely different monster. Hence the saying "power is a downshift away". If we are talking about street cars still, then earlier spool is better. So obviously you need to have enough back pressure to support your goal. But who the **** puts a set of FullRace headers/uppipe on a street car? Oh, the knuckleheads driving on public roads in what is really a race car.

MDKSDMF Posted May 30, 2011 Share Posted May 30, 2011 im getting the fast motorsports headers for their price. I will then bring them straight to a friend/welder and have all the welds reinforced and the headers looked at and touched up if need be. This was suggested to me from my tuner whom i trust very much. yes the extra welding will cost some money but it will also make the three hundred dollar headers last longer. i also agree with spranks previous post. for a street car, the full race headers are not necessary considering the price.

MDKSDMF Posted June 2, 2011 Share Posted June 2, 2011 I dont think any header is guranteed crackprooff for life :lo: Link to comment Share on other sites More sharing options...
m sprank Posted June 2, 2011 Share Posted June 2, 2011 Borla is. They also honor the warranty. But you will be swapping headers every 6 months or less. In my experience. My last customer who bought them had to warranty them twice in 3 months and finally sold them. Link to comment Share on other sites More sharing options...
