It's pretty flat here. I live in Chicago so most of the time my brakes are used in panic stops avoiding potholes, pedestrians, and people who can't accelerate going into suicide merges. Previous owner lived in NYC and between the two of us the brakes only made it to 23k miles.

Hmm that's strange, I guess the wrap could absorb vibrations and alter the way the sound resonates but I'm no expert

My next purchase is going to be uel headers I'm just worried about 2 things, rasp at high revs and a cel, have you thrown any cels with yours ?

UELs won't throw a CEL, but a lot of catback setups will. UELs give rumble, not rasp. The only way it would be raspy is from your exhaust/cat/muffler setup

Right now I have a 3" invidia wrx cat back with no resonator, it's got a lot of lows so it kind of drowns out the rasp at High rpms

18k on the pads currently and going strong. Considering I push the car pretty hard out in the canyons it wouldn't make sense if mine out last yours lol. For the record its the Stoptech street pads.

My UEL's made me throw P0031. At this point, the only thing I think it could be is that the sensor got damaged because can't think of a reason fro this code coming up with UEL's because its for low voltage to the sensor heater (and even when the car warms up, the code stays on).

Lol? UELs wont throw a code? Tell that to my p0420 that goes off every other day. My catback never threw a cel with my stock headers, ever. My rasp is due to magnaflow high flow cat and no resonator in my catback. When I had the resonator in place the rasp was very minimal but still present when the car was not up to temp (low rpms/high rpms).

Before I got my headers and I just had my catback, the rasp was only present during when the car was cold as well. Once it heated up the the low end rasp would be gone but occasionally you could hear rasp on the high end. I did not have a resonator at that time.

Just my experience so far.

"UELs won't throw a CEL"

I think they can. It's one of the reasons I don't have one right now.

I guess all of you have different UELs then. My Borla UELs have never given me one (I've had them for 3-4 years now), but my magnaflow catback did. When I had my hi flow cat with my magnaflow catback, it was raspy a lot too, especially at high rpms. I switched to a normal cat and it made it way less raspy and deeper.

The last thing I need is to spend that much money and throw a code, especially since my inspection is due sometime this year

I've contemplated go muffler-less but instead putting a second resonator in its place. that'd keep a lot of the tone and volume but cut out the higher frequencies and rasp.

Unless you're running a 3" setup your catback shouldn't cause a cel, but headers definitely can cause it. It appears to be a combination of the lack of insulation and the often aftermarket HFC. With the HFC and the lack of insulation the system tends to identify the change in exhaust flow and cat heat up as a problem.

Headers definitely cause a CEL. The fact that there isn't a cat in aftermarket headers is why a p0420 would occur.

It's not so bad here, if I fail you just pay 200 bucks for a "pass" it's such a scam, they don't even start your car anymore..

Working on repainting these today, going with satin white and clearcoat. Sanding off the crappy blue paint job first. Next is my Cusco strut bar.

Any damage? Where I used to live some of our roads were the original brick that had just been paved over top of. Every season giant swaths of asphalt would breakdown and disappear leaving 8" deep holes for your car to fall into. Good times.

None that I've noticed, luckily! But it was brutal, had to be like 4 inch deep and like 8 inches wide. I normally avoid it but this time I forgot about it

Lol I can find these cases non stop all day. The point is UELs are pretty much guaranteed to toss a code. My rallisport's were code free for about 6mo. My friend has went through 2 borla rep uels and 1 borla uels his 2.5i all which threw p0420.

Side note my catback is 2.25in in diameter and to sum it up less heat retention due to the stock headers being thicker then 304ss.

Stock headers are not only thicker but also have the baffling clamped onto them. All of that contributes to heat retention most aftermarket setups don't have unless wrapped, coated, or both. I'm already coated and wrapped is next.
