Gentlemen of Club WRX (and ladies):
I have searched, and have a few remaining questions to answer.
I have recently decided to go the route of Equal length headers and protune after getting used to my TP stage 3 tune. I'm looking to get the stock turbo spooled-up a little earlier than stock and to get more tq on the left side of the graph, so keep that in mind with the suggestions. I also daily drive the car, in all types of weather, so have a few concerns about the SS headers in general, and wrapping in particular.
I have narrowed my search down to Perrin's ELH, and Tomei's ELH, both of which have been recommended by different tuners for different reasons. Both are in the same ball-park for cost. I'm trying to decide between the two, and have reached a small stumbling block.
The good thing about the perrin is that you don't have to change the uppipe, so installation is simpler, and to maintain the warranty you don't have to heat-wrap it. I have also had very good luck with perrin products on my car. The negatives are ... you don't heat wrap it if you want the warranty. Also, with no heat shields, I'm concerned of general heat soak/melting of bits.
The Tomei kit comes with everything, and has been highly recommended by a few people. However, you have to change the uppipe, which limits the ability to get an EWG (without chopping it up) in the future, and takes mildly longer to install. Also, you heat wrap it, which seems to be both a good thing (for heat) and a bad thing (for durability).
So my questions:
Can anyone comment on the durability (cracking issues? heat issues? install issues?) of either product that has owned if for more than 3 months? I plan on DDing the car for 3 more years (minimum), so I'd want the headers to at least last that long.
Can anyone who lives in a slightly salty environment comment on the headers ability to resist corrosion? Both are 304 SS, which is decent against rust, but is definitely not 'rust proof'. In other words, in 3 years will I have a pile of rust under my car, or will they last decently?
Thanks in advance, for any help you guys can offer.
