Honestly I couldnt tell you for sure. I picked a header up and a stock set up and there was very little difference. Felt a tiny bit lighter if any.Do you by any chance know if aftermarket headers are lighter than the stock headers?
Thanks. They are actually just universal magnaflow mufflers welded to the stock piping. I'm planning on buying a complete catback setup soon I don't like how raspy this setup is during normal driving. Sounds really good at wot though. I think I'm gonna go with mbrp setup next.That sounds really nice.
What MF mufflers?

Well I don't know how it works everywhere else but my car is definetly not considered legal here in California I'm just taking advantage of the new car 5year smog time frame lol.as someone who just got into the exhaust research..does this make your car technically street illegal because catless?
Yes I believe you will be very happy! I know with slicks and axles my car would run 11s I have a video of the pass on Facebook but can't get it into YouTube. My car was all over the track 1st-2nd and 2nd-3rdVery nice , I just ordered a set myself from Beefcake ..I hope I pick up as much as you did , I would be very happy with that gain .. 3 tenths and 3 MPH is very good![]()
