Default cracking borlas?

so this might be a bit newbie-ish, but obviously a lot of borlas crack
I assume this is because the rapid changes in temperature a header goes through (especially if splashed going through a pulle or something) and the fact that borla may not use as high a quality of welding as the headers costing 2x as much.

One way to try and alleviate this as far as i can tell is wrapping the headers..
but this inevitably attracts rust and salt come winter...

do you think having a skidplate installed would help protect the header?

A skid plate would help prevent thermal shock to the hot pipes (driving through standing water). But the only problem is that currently there are no skid plates that will fit with the Borla headers installed. I think they hang down too low for the skidplate to fit properly.

crappy....
good thing i didn't buy the borlas quite yet....that rallyarmor plate is already installed...

how much clearance are we talking about? like way off, or is there some way to make it fit?

other headers fit though?

the 04 wrx sway bars fit the 04 rs... well thats what racecompengineering told me. i have the cusco 21mm in the front and when i floor it on first i hear the sway bar hitting the headers... i was thinking about swapping out my front sway bar for maybe whiteline or something and see if it helps...

the front sway bar actually made a noticable difference in turn in, the car has a very slight lean in during cornering.

I have a Primitive Enterprises skid plate on my '03 OBW I was planning on getting a set of Borlas! I will contact Paul Eklund about this issue of clearance he would know. Also from what I understand the new generation of Borlas don't crack!!! Most of the problems were with older headers(couple years ago).

I've got 40k miles on my Borla and it hasn't cracked or even shown signs of aging. This is on a MY00 with an A/T. The only negative thing that i've experienced is that it used to heat up my transmission because of how close it was to the tranny coolant line. I now have a tranny cooler and have since moved the line. So no problems.

I would pay extra money for Borla to make slight modifications to their current 4-2-1 header. I wish it had better fit and finish along with better pipe routing. I wish I could buy them (I love the sound they make), but I rather not worry about having them crack while I'm on a business trip somewhere.

I got mine not to long ago...Borla Header's that is from a blowout deal on one of these threads...can't remember the thread title...but it was Brad from Titan Motorsports I think...and I've only got about 3-6k miles on them....and they seem fine...also, I thought Borla has a millon mile warranty? Anywho...I was told this latest model of Borla header's are good against cracking, I guess we'll see after winter...how they hold up...I'm sure they'll be fine...if not, I have that warranty to fall back on....and for the price I got mine for....can't complain yet.....

Borlas wrap around the oil pan and droop low... the skid pan would be extremely low

Heres how they look like on a GC (I think they are similar on the GD)



In comparison to a stock set of headers....

The Rally Armor plate is angled just enough for the Cobb headers to clear, without being too low


(Here it is bolted)

I've had my Borla header for 10K. Sounds good and gives good low to mid range power, not much on top end. I've heard that turbos put exta weight on the end of any header due to the up and down pipes. That may be the source of cracked header complants. For NA I feel the gen VI Borla is a very good choice for street use.
