Ok guys did some more reading LOL. So check this out, this is what I am going to get done and I hope it sounds good if not oh well.
Keep in mind I have a E90. So I will replace my resonator delete with the magnaflow xpipe that was linked earlier in this thread. For the OEM mod I am going to remove 100% of the packing and wrap the perforated pipes in both mufflers with titanium heatwrap. JUST LIKE this guy did in his E90 M3. http://www.m3post.com/forums/showthread.php?t=869384 Thoughts? |

If I remember Tomz_M3 removed the packing (all of it) and replaced the pipes with non perforated pipes and his car sounded pretty nice.
Do you mean a honda civic tin sound? I am trying to avoid that sound at all costs, so 50% of the packing and wrap the pipes? Is wrapping the pipe and replacing with the straight pipe going to generate the same sound? Confused again. |

OEM stainless steel is also a lower grade than the 304 SS that is in high-end aftermarket stuff. That might make it easier to weld, but I'm not sure. Properly welding stainless requires TIG welding as far as I know. Quote:

Iphone? I just really want to hear what they sound like with catless downpipes and the e90 resonator still in. Even a phone video revving the car a bit at a stop, then maybe put the phone somewhere and do a quick 1-3 pull driving away would be perfect and i'd really appreciate it. I just want to make sure I 100% want to try this before I invest money in having it all welded with new tips and whatnot

I'm still a bit behind on my project, but I'm confident to duplicate the PE tone. I'll post up video once I got a hold of a reputable welder in town. |

I actually think you're in luck. I'm going to pick up a GoPro this week, so I can get some actual clips while moving. I'll take a cold-start video and some revs, too.

^ Majority of the people here are looking to increase the noise level, but your looking to reduce the noise level?
Guess the easiest way for you to do is, swap your Performance exhaust with someone who has the stock non-performance exhaust. |

So you have a Performance Exhaust. Do you have any cats on the car?
