My New Custom Exhaust SUCKS ...suggestions
well I removed the pre cats, went into a Y-pipe into a single mangnaflow hi-flow cat. From there it goes into a new resonator and then just the stock muffler.
Sounds good, nice and quiet BUT at 3.5k and higher there's a tinny resonating sound coming from the Y section! WTF!!!!
Is it too restrictive? Also, it feels like the car has less power now which is NOT good. I think I just wasted money on these new exhaust parts and pipe bends/install.
I just don't get why the noise is coming from the Y section ...the piping is fairly big too. The inlets to the Y are = to stock (I think slightly bigger) and the outlet of the Y is = to the stock piping that goes back to the muffler. Should I ditch the Y pipe and get a 2-inlet, 1 out cat and use that as the Y? I'd just hate to buy another cat only to find out that was a waste too.
What did all you guys do?
