I used spacers until i had it welded one piece straight back. I would get it tightly fitted together but it would loosen and hit the cross brace.

 

thanks i will try that

 

If you're hitting the cross brace, why not get new exhaust rubber mounts?

 

The mounts im sure are ok, it is how the pipe is clamped/designed. If not tight enough it developes a "sag" to say and will droop then rattle on the cross brace.

 

Another quick fix: have it welded.

That is what I did because I do not intend on selling the exhaust any time soon. Haha.

 

Sounds great! Thanks for the clip.

 

I think I am going to take my brace off until I get the exhaust welded. It is not rattling off the brace it is banging and the rubber mounts are fine.

 

Idk about anyone else, but my rattling was caused by the inside of the muffler tips coming lose and banging around. A quick spot weld fixed the problem. None of my pipes are welded together either and I haven't heard a rattle since.

 

Hey guys, read a few pages of this and found the same issue I am having...I have maybe 1/4" clearance at the front crossmember. At high speed, well highway speed of maybe 75 and up I get a terrible vibration and can even feel it in my feet. I know that's where the issue is, but my exhaust is welded. Is there an easy fix to drop it a little lower at that point? Do they make lower rubber hangers? Take it off and get the tube bent there?

Thanks, it's driving me nuts!

 

I need to space my bracket a little more and cause it is still banging.

 

Just to clarify, I'm not talking about the cross brace in the middle of the exhaust, but the piece directly after where the pipe bolts on the downpipe. I don't know what that piece is called. I WISH mine would sage more in that area, it's up too high. Suspension compression is causing it to rub at high speeds.

 

I am just stating mine is bouncing of the brace. I had it tighten down with an impact wrench and it is now hitting the brace once in awhile.

 

User 1/2 inch spacer between the brace and the body kept me rattle free until i welded it.

 

Anyone had issues with getting the Q300 to fit into the Riss Racing DP? I can't seem to get it in without popping off the v band.

 

It should fit with no problem...

Only issue we had was that the Riss DP was slightly shorter than the stock DP...so I had to shove the Invidia as far forward as possible.

 

Yeah, I got it in, but I doubt its going to stay.. Sounds good only one leak from the front C-clamp but that should be fixed by adjusting the mid pipe

Soon as I started it up, I thought

 

So this morning on the way to work, I got a CEL. I was like are you kidding me. I thought it was referring to my recall on the Auxiliary Water Pump, but according to the manual, with the icon and the way it flashed up it says that it has adverse affects to the exhaust emissions. Obviously, I am in the Invidia thread, so I have the Invidia Exhaust System with Resonator Delete. Not sure what would cause a CEL, and it can't be my Exhaust system, since I only removed the after CAT that is not being monitored.

So I would say the Engine is not performing at where it needs to be so that is why it is giving off bad emissions, because obviously the Pre-Cat (before CAT) with sensors detected a bad emission. So would you guys say that the engine is not up at optimal performance? What is your guys take on this matter?

 

I'd say read the codes and see what the matter is ....

 

ScanGuage reads P0136, O2 Sensor Circuit (Bank 1 Sensor 2). So a bad sensor. If that's the case, then its a good thing that I am still under warranty by 600 miles.

 

Quick Question for you all that have the Q300
How many installed it without the resonator part and how do you like it ?
Does it make a huge difference with or without it ?
Did you buy a straight pipe to replace the resonator part or only put it on without it ?
Thanks

 

I got the resonator deleted and then flanged in a straight pipe. I like my setup a lot. Stock it was just too quit, Invidia system with res, was definitely more loud, but still wasn't cutting it. Once installing the straight in place of the res, it become a little more louder, but not that much. Tone change was more in regards to aggressive sounding and you get pops and burbles once it awhile under 3,000rpms. For now I am satisfied with my setup, but once I am out of warranty and the maintenance plan I will be messing with the fact of getting a down pipe and then a tune to get rid of the CEL that will appear because of the O2 Sensors.

Is it worth getting it replace with a straight, I think so. A little more sound, a definite growl/tone change that I like and enjoy, (people turning their heads), performance - nothing, and maybe .5 to 1 more mile of mpg.

 

how much $$ to do that though

 

Question to all that have installed the exhaust, what would you guess the weight difference between stock and the invidia to be? I'm not thinking it will be a drastic change, but I'd like to hear that in hand the invidia is noticeably lighter. Thanks!

 

Borrowed my buddies GoPro Hero2 cam and finally made 2 clips of my Invidia System with Res delete.
Here they are if you want to hear the difference. When you go to youtube you can just look at my clips with the res on and w/o and hear for yourself. Let me know what you guys think.

I would like to know what are the horsepower gains on the Invidia? Thank you.
