I only have an idle video, never got around to making one under load.

I just found out from the noweeds website, that it doesn't work for the convertible.

Major disappointment. I thought this was really cool. Still do actually.

I have 3 inch no weeds and 1-7/8 AR headers going on my cammed ls3 with MBRP exhaust. I have to get some custom work done as they will not work as is, with this X pipe, but it is going to be nasty when it's done!!!

serviceguy · 02-13-2014, 08:16 PM

does anyone have a video of the no weeds system with OEM cats ?

Nickey31 · 02-13-2014, 08:32 PM

2" kooks headers with no weeds

thespymaster · 02-13-2014, 09:25 PM

I have American Racing Headers with QTP cutouts and Corsa exhaust and when QTP is open and I'm at WOT sounds pure nasty

SargeantSarcasm · 02-13-2014, 11:41 PM

I have the corsa catback on my zl1 right now...if I added the noweeds would it throw up a check engine light?

Cat988h · 02-14-2014, 03:46 AM

No it should not the Cutouts are just behind the o2 sensors so the car will not even know that they are there. I have read that it may change the air fuel mixture but I'm not sure on that. I am going to data log my car after I install mine to find out. No tune is needed is what I understand.

I guess I'm a little curious is to why. That seems strange to me.

Did someone post a little while back that cars wouldn't pass inspection in certain states if they had cutouts? Anyone remember something like that? Maybe I'm remembering wrong.

It's just a short clip of me at autocross but this is with the stock headers and Cats. I will be making a comparison video of completely stock vs stock headers with NoWeeds vs PFADT header/no cats with stock exhaust vs PFADT headers/nocats with NoWeeds.

I don't know why it wouldn't work, I decided i was interested enough to shoot them an email this morning to find out the answer.

I'm not sure, I would think if that was all you had and you switched it the NoWeeds to the stock exhaust position (closed) for the test they wouldn't even be the wiser.

Personally I think cut-outs sound like absolute garbage. Add in open headers and it's like a redneck truck imo, but exhaust is always a personal preference and not everyone will agree.

HDRDTD · 02-14-2014, 08:29 AM

I doubt the noweeds would work on a convertible because of the additional bracing on the bottom of the car. I'd expect the bracing to get in the way.
