I have always like the way the GMPP sounds. A friend has one on his E85 M62 2.7 car with a vibrant header and dp and it sounds great.

So even on a 300+ TVS balt I could run the GMPP 2.25 and be no different than the 2.5 corsa I have on there now?

It is nice and quiet, which is what I wanted for my daily! I need to get some rotated mounts though, as the poly ones are not as DD friendly

If you have a 2.5" exhaust already I wouldn't downsize. Especially since the corsa is so nice. FWIW Kenny (zrated) ran the gmpp on his built TVS setup.

Primary reason I kept it. IMO the best sounding exhaust you can get for a blower car.

Yea that's why I went back to stock after having the ZZP Midlength. Sounds so much better.

After driving around with the zzp header and 2.5" catted dp with stock catback, it sounds so nice and quiet. Perfect for what I will use this car for. You can still hear it, but its just a deep quiet tone. Its odd because this downpipe and catback are from a friends car, and with the stock header his was so unbelievably raspy. I thought either the cat or the muffler was coming apart causing the rasp, but on my car there is no rasp. All I hear is the sweet serenades of the little M62 screaming in the cold air at 7600 rpms lol
