I installed a 3" X-Pipe, deleted the 2nds, and ran a straight pipe through the resonators. The tone down low is much deeper and small blips produces a noticeable V8 sound. Not subtle at all. WOT, it is difficult to tell with all of the other noise the car makes. Neighbor says it sounds much better as I drive down the street away from his house.

^^^^ haha your neighbor knows not to mess with the beast!!!

So, do you recommend taking out the cats and putting in the x-pipe or do you think just removing the resonator produces the majority of the extra sound?

I heard another members car on here a while back which had 2nd cat delete and straight pipes vs resonators, no x-pipe. Sounded almost stock, no deep V8 tone at all.

I also have shorties installed which made it a little louder, the combination of everything really came together. I'm happy with it, not loud, not too quiet, just deep.

Neighbor has a 350Z, went for a few 0-130 runs in my car, came back, he has been very quiet since. Other neighbor has a C6 and another a SRT8. Neither wave to me anymore.

mikey33

cool. I think I will just go with the x-pipe in place of the 2nd cats and straight pipess at the resonators.

Do you think this is a good x-pipe? It is cheap and I do not see how it can be much different from the more expensive magnaflow.

That's the one I have, everyone I know that has used it is impressed. Exhaust shop thought it set me buck much more and said it was as good as anything he had or seen and they work on custom HotRods. I would pay double that easy, really built unit.

mikey33

cool. I will buy it than because I do not think the shop I am going to have my stuff done at will have one for that cheap. Last freakin question, sorry, the 3" diameters are correct?

pearlpower

Yes, 3" all the way. May want to show them pics in case they try to remove the cross brace instead of tucking the pipes above it.

mikey33

Okay!!! I just ordered the x-pipe and will wait till I get it to have it installed, but tomorrow I will do the resonators

Big time weight savings also, those cats and resonators add up. I think I saved around 27lbs weighing in everything.

mikey33

Sweet! My whole goal though is to gain loudness because I am thoroughly unimpressed by the meisterschaft exhaust thus far.

mikey33

Never thought about the weight savings, but I am sure it can only help! Thx for all the help. The only question I have now is if the shop I am going to will want to take the secondary cats out or if I should even ask in case they might get mad at me saying it is illegal.

Very nice set up. Can we get some sound clips please?

X2Board

I have a custom X pipe, with secondary cats deleted. Quiet at idle, no drone and sounds perfect at WOT.

Don't forget to keep in mind what mods certain guys have...i.e. don't expect to get the same sound results as somone with headers, etc., if you're stock.

mikey33

true that ^^^. Never thought of that aspect. Got the resonator removed with 3" straight pipes and the loudness did not change at all at idle. I will mention though that when driving the car it is louder, maybe 25% - 35%, and I can hear the exhaust at all times unlike before where it was only at around 1800-2000 RPM's or at WOT. So, I do have sound now throughout the RPM range which is an improvement. Was it anything dramatic, no way, but was it worth a shot and $85? Yes. At least I can sleep well at night

Next, X-Pipe on Friday to finish off the exhaust.

sounds like you're going thru the exact same process i did...here are my steps and impressions along the way:

1) replace reso with 3" straights -- honestly, very little diff IMO

2) replace sec cats with 3" straights -- def got a noticeable sound diff, however, butt dyno showed loss of low end torque and got some drone on freeway

3) put in x-pipe where reso used to be -- perfect set-up for my taste. the x-pipe really refined the sound. still the perfect increase in sound IMO but no more drone on freeway and got my low end torque back (based on butt dyno only).

hope this helps

mikey33

Yeah that helps a lot!!! I am going to do the opposite though and put the x-pipe where the 2nd cats are. I think either way we will probably have the same result with me gaining back my low end torque and having the sound refined and louder. It feels like I am going insane when trying to figure out what was the difference with the before and after, but after listening for a while I do know that there is a difference and it definitely was worth the $85 and fun at the same time, money well spent

acr-c

Are you saying that now you can hear the exhaust 25% to 35% louder at all times, whether at a city speeds, constant cruise on the freeway at 75 to 80 mph and at WOT? Thanks! I'm trying to figure out how to quiet mine down on the freeway only. Everywhere else I love the sound.

Christian

mikey33

Yeah, the car is about 25-35% louder at all times which really makes it perfect sounding and scary at WOT!!! I cannot imagine what it will be like when I install the x-pipe on Monday, but I am going to post a video of my current set-up tomorrow before the x-pipe goes in.

Do you know where can i find this x-pipe on website to order it , can you help me out

e551986

If you have a chance can you take pic under your car in muffler shop and post it . thnx
