So, I'll ask this question. I love the way the PSE sounds, but it's not loud enough. I would like something in between the PSE and muffler bypass pipes, any suggestions? I also want to avoid any drone, idiot lights, and fittment issues. Performance gain and sound is what I'm looking for! I used borla mufflers on both my E46 M3's and loved them. I wanted to go with them again, but there is alot to chose from and all have there own distinct sound. I plan on spending about $4500 in exhaust, and ? for an intake. So what do you think will suit me the best?

Getting the sport cats made a BIGGER difference in sound than the headers or exhaust. I added these components at different times so I have a good idea about their relative impact. Getting headers with sport cats along with the PSE will definitely be louder than the PSE by itself. Might be what you are looking for..

I guess it depends on the software and the dealer. My dealer encourages software upgrades, such as Revo and claims there is no warranty issue. I suppose there's a big difference between a minor value swap via an ECU flash and removing an ECU and soldering things to it, or physically changing it.

I agree. Brandywine Porsche does GIAC. I think they would have a hard time rejecting a claim and blaming the chip when they put it on in the first place. I don't know if any local dealers do revo. Brandywine isn't too far from you NYKID.

Thanks for the responses! This is not a budget build up, but there is couple hundred dollars difference between the X-51 headers, and the others. I dont believe in throwing money away, but spending it wisely. Thats why I asked about the evo and suncoats headers. There do look extremely similar, but which is better quality? Right now I have the muffler bypass pipes from fabspeed. At $300 I figured it was worth the try. I personally think it sounds amazing and so do my buddies, but the interior noise is alittle excessive. So thats why I'm looking into headers, cats, and mufflers. I want to do this once and be happy with my choices and not want to change out parts because I don't like the sound. Did it with my E46 M3, paid $1k for mufflers and the next week spent another $1k to replace the ones I just installed.
So, I'll ask this question. I love the way the PSE sounds, but it's not loud enough. I would like something in between the PSE and muffler bypass pipes, any suggestions? I also want to avoid any drone, idiot lights, and fittment issues. Performance gain and sound is what I'm looking for! I used borla mufflers on both my E46 M3's and loved them.

I'm looking into purchasing headers and an intake. Which headers would be best (fittment, quality of product, etc.), X-51, suncoast, or the evo headers. As far as the intake goes, does anyone have experience with the evo? Also, I was concerned with the airfilter, when I had my E46 M3, Some members on the forum had problems with the pre-oiled filter. The oil built up on the Mass Air Flow sensor and caused failure of the sensor. Thanks for any info provided.
Anyway, the Suncoast headers are very good. The fit and build quality are excellent. It does change the pitch of the exhaust quite a bit (much higher), but it still sounds good.
Regardless, butt dynos mean nothing
Here's my car. Stock cats, stock plenum, CG mufflers, and the SC. Before and after. Same day, same dyno. The runs were done within about two hours of each other with only about 2 miles of drive distance between the install shop and the dyno shop. Yes, I know, my car has a SC. However, I've seen the exact same results on NA cars with this product. Suncoast predicted these gains to a tee based on their previous testing. I didn't end up with any "bonus" hp because of the forced induction, even though I had hoped I would. Plain and simple, it works. With regards to the power loss on the bottom, that is the nature of exhaust tuning. Give some to get some. They all do it. You can't have it both ways.For those that are spending significant amounts of money on these very expensive mods, you really should be getting your cars dyno'd to make sure you're getting everything you're paying for. Trust no one

Boosted and NA engines respond differently with the above modes. BTW DOG, when are you going to eliminate the resonance valve on your car? It is not needed.

I don't even know what a resonance valve is. Can you explain? No one has brought that up before.
