GTI 337/20th Anniversary :: Exhaust Leak And Bad Gas Mileage
Some questions I have regarding he bad gas mileage my car is getting. Up until winter, my car (2005 mk4 gli) was getting 300-330 miles to the tank. I thought was reasonable, about 150 to a half tank. The setup is pretty normal, apr stage 1 tune (87,89,93,100 octane) with bolt ons (upgraded n75, DV, things like that), a cat back exhaust (unsure of brand), 90k miles was just passed last week. Timing will be done in the spring.
The car has no stutters upon acceleration and idle is staying pretty consistent about 900 rpms. I know there is an exhaust leak, at the flex pipe as I seafoamed the car this fall and discovered that. My question is, which down pipe to you suggest to be the best for the money? I've seen a bunch of different brands, weather it be 42dd, ecs, places of the such.
Would it be cheaper and more efficient to just get a turbo back or stick with the cat back and stay happy? Also, I'm assuming if the leak is in the flex pipe, that the down pipe needs replaced all together. The car DID have a check engine light, for the leak. Since winter the cel has gone away and the gas mileage dropped drastically. When I get a new down pipe or fix the exhaust leak, I also want to change the rear O2 sensor. I believe personally this maybe causing my gas mileage info.
Lastly I have a fuel filter to replace the oem one that's been in there. The same thing happened to me last winter and when summer came around, the gas mileage went up to normal 300-330. I drove to h2oi and was getting well over 30 mpg. Now I'm lucky to get 18mpg.
GTI 337/20th Anniversary :: Dead Ringer For A Throw Out Bearing Noise
20thae with a UR 7lb flywheel and spec stage 3 clutch. Got rid of the dual mass flywheel and installed a lightweight flywheel and spec clutch now i have a god awful noise that is dead ringer for a throw out bearing noise. talked to the spec guy at waterfest today and he told me that the dual mass acts as a dampener and this just doesn't make any sense in my head. touch the clutch pedal in any gear at any speed and the noise disappears.. uy at spec said it was in the trans and the only option was to change for a thicker gear oil. p.s. i took out the clutch and everything back apart and measured everything is oem thickness and the throw out bearing is in good shape.

The other day my transmission was driving fine, until I stopped to let someone out. When I tried to throw it back into gear, it wouldn't engage at all, just had a slight grind almost like the sound of a chain coming off a bike (so I pushed back in the clutch and parked it). I haven't been having any issues with it nor have I been driving it hard.

I have a code that just started popping up on my 2000 Yukon XL2500 with 93K. I know I have a spot on the side of the Muffler that was rotted out and patched by the previous owner. My question is would an exhaust leak that far back in the system throw off the O2 Sensor?

I recently just put a set of b&g rs's on the car and now it appears that my 3'' exhaust is hitting and rattling/striking the bend that goes over the rear axle, I know I can raise the car and keep it from doing such but that kinda defeats the purpose of lowering the car, Just trying to see if there is something out there, like polyurethane hangers or something along those line that might alleviate the problem.

I have a 42 DD tb exhaust. And so far I've used a 3" exhaust clamp over the last hanger (after the muffler) which raised the exhaust all the way up against the heatshield, eliminating the rattle over the rear axle beam. But the exhaust was rattling against the heatshield.
So I bought 15 ft of exhaust wrap and wrapped the section that comes in contact with the heatshield. It worked a bit but it still rattles a little! I hate this rattling! How to get rid of the rattling? Should I just use more exhaust wrap?
GTI 337/20th Anniversary :: White Smoke Coming Out Of Exhaust
Literally drove the car yesterday for three hours nothing was happening. Went to turn it on today when it idols a little constant white smoke comes out of the exhaust! Then when I'm driving and my turbo boost lets out a big cloud of smoke comes out. What could this be? Also just filled my car up with gas from empty today if that matters

So I recently swapped out my cabin air filter, no other major changes or issues... but ever since I noticed that when I'm in neutral or at a stop, I can start to smell the faint odor of exhaust fumes. No CELs and it's not coming from the gas tank area like I know some have experienced - only from the vents. It's noticeable to me, but nothing unbearable by any means. I definitely never had this before - and my old filter was really dirty so not sure why a new one would give me any issues of have anything but BETTER air quality. I notice that I can curb the smell by pushing the circulate air button, effectively shutting off any outside air from coming in.
