I decided to hold off on purchasing the M performance exhaust due to it not having valves, so i pulled the trigger on a remus midpipe (just a regular straightpipe center)

before i install this and regret it due to drone, does anyone have any clips of their straightpiped resonator with the valves closed/open

[jivom5]

update: i did the straightpipe and holy SH*T this sounds incredible. however its still pretty tame with the valves closed.

Awesome, maybe post a sound video if you get a chance. Just to clarify, the midpipe just replaces everything from CATs to the muffler correct? or are you CATless?

correct just replaced the center resonator/ stock cats/stock mufflers

Confused. Did you only replace the mid pipe or are you straight piped? Two very different things.

Sorry to hijack this thread a bit, does anyone know how to get rid of the rasp at part throttle between 1700-2000 rpms that came with removing the cats? I was thinking maybe doing something with the mid pipes but I know nothing about exhaust.

Thanks for the recommendation. I guess I'll have to try it out.

I have catless downpipes, Remus midpipes (so no resonators), and the back box is gutted out so nothing inside it. essentially a straight pipe

I have a little bit of rasp as well. I am OK with it. But there is also a slight vibration or rattle from the rear of the car that I hear at low rpm when I start accelerating hard. I think it is related to the exhaust valves but am not certain. I put the car on the lift and checked pretty carefully for clearance issues and did not find any. I would think the valves are open at that point but maybe open valves can rattle.
