Yeah, they do at least, so that's the good part. Another reason why I went with the JDL. I run into a problem with it, it gets replaced.

I only got a gasket for the collector/front pipe. Do I re-use the gaskets for the heads?

Either reuse the gaskets or buy new OEM. I bought the installation kit from JDL, but I'd have just reused the old gaskets because they're MLS.

That's what I figured. The gaskets were in perfect condition so I used the same. I successfully installed the headers today, but I'm getting a loud flappy/clicking sound when I step on the gas. Anybody else get this? I'm going to assume a leak

Sure sounds like a leak. Make sure it's seated nicely on the overpipe.

I called up JDL and they said that every header they've installed with the stock overpipe had produced the same sound i described earlier. Can anyone else confirm/elaborate? Many thanks

I have just received my EL header and I DO NOT have any flex joints on it. My order was placed during Black Friday of last year. After receiving it, I called JDL Auto and they just informed me that they no longer use flex joints on their EL header design. There are flex joints on all the pictures on JDL web site and the forum; and I did not find any information on the web about the update of the design nor was I informed regarding to the change of design during my order. Did JDL also change the flex joints design on the UEL header? Can anyone else on the forum who had received their header recently verify with me on this information?

The first couple headers we built roughly ~2 ½ years ago didn’t use any type of flex joint. When we decided to make the headers a production part I decided to utilize a flex as OEM does and frankly at the time didn’t have enough usage on the prototype headers to deem it unnecessary . This backfired on us big time as Vibrant performance flex joints we were using all failed resulting in us warranting the first~30 headers. At that time I built a few more headers without flex joints to put a few local buddies’ cars so that I could monitor them as the prototypes had all been sold. We continued using the flex joints just switched to a different brand and style. Fast forward 2 years to now and there has not been 1 single issue with the non-flex headers on cars. I feel comfortable going forward without the flex joints. This will help the headers become more of a production part and should cut lead/wait times down in the near future. If anyone has any concerns, etc PLEASE feel free to call. As always the headers are backed by our lifetime warranty that we stand behind 100%.

Thank you for the clarification. I just wanted to verify if any other members of the forum had received their header without the flex joints. I did call and speak to Debra on the phone. She was very kind and she tried her best to help. The welding and the quality of the header is definitely top notch.

I've hear now a few other ELs like Buddy Club etc and the rasp alone would drive me nuts I think. :-/

Yeah, cold starts aren't too bad. It's not as bad as when I ran the N1, lol. The thing I love about the Perrin catback is its loud when you want it to be loud. Otherwise, it's a nice, civil UEL rumble while you drive and shift normally. That was my issue with the Q300. When I did drive normal, I couldn't even tell I had a UEL header inside the cabin it was that quiet. I think Perrin nailed it by using a large resonator and a not so large muffler to get that tone perfect. The Q300 is great for people who want the power but don't care for sound. I would have to go catless to increase the volume on the Q300 and I didn't want to do that in case I need to pass the sniffer inspection if it comes to my area.

Did you have problems with your Catted Front pipe fitting the Perrin 2.5 catback? I saw that someone mentioned that the way the flanges were made it would not fit. Did you make any special request for it to work or did you order the one just like the pictures on their site?

I told JDL to make a flat flange so I had 0 fitment issues. You will need to do the same if you get one. Give them a call or email them if it's early so they can note that and make it a flat flange to pair with it.

For peace of mind i never reuse the gaskets, i used the grimmspeed thick header gasket. Now do keep in mind most if not ALL headers RASP!! sounds like shit when you get on the gas, not sure if you're running catless EL, or UEL but they rasp. It could also be a leak as it sounds the same. Does it do it when you give it gas only, what about lightly applying throttle. Its not only with stock overpipe at least not in my case. I uploaded a couple of videos when i installed my ptuning header, look up "yomny" on youtube, can't link them here as im at work.

PS- if it does it at idle and after being fully warmed up, then its most likely a leak.
