My Headers & Exhaust Setup
#1
![Default](https://www.clublexus.com/forums/images/icons/icon1.gif)
I haven't posted threads dedicated to my mod upgrades, but now I'd like to share because I haven't seen any member here flange their cats once installing headers.
I bought Vband flanges and had them installed. I also had some straight pipes made up for "track use".
These cats from PPE dramatically reduce all rasp heard cat-less. The rasp isn't an annoying to me, it actually sounds good. I miss it. The overall sound is about 15-25% louder tone than just having a JoeZ exhaust. Catless I would say around 25-40% louder in tone. The tone is deep with sharp blasts of rasp catless.
I do feel some additional low RPM low-end tq with the cats on.
Enjoy.

I don't mean to hijack the thread, but its sort of on topic, except on my 350. I'm planning on running the same set up as you. PPE headers with cats on v bands, bc a v6 rasping is terrible compared to your v8.
My question is, do you guys think resonators will reduce rasp if I add some along with the cats? Or do only CATS reduce rasp?

Very nice progress thread!!!

I can just imagine how much LOUDER + DRONE + RASP it would have without the dual resonators we manufacture for our system...
The CATs are changing the sound wave lengths inside the piping.. That's why you can hear a difference with the additional CAT's added..![Wink](https://www.clublexus.com/forums/images/smilies/wink.gif)
The resonators are the true tuning factor.. Having the RIGHT ones, makes a world of a difference.
PTS made sure we covered ALL corners when we finalized our design over 3 years ago..
Congrats on a job well done..!!

Thanks Joe Z!
This setup is probably the most ear friendly to the general audience, and is HIGHLY reccomended by me. Even for my Cali citizens. Swap in the test pipes and its for the pure enthusiast (like me). I miss the catless low rpm backfires! I couldnt even imagine the sound without the PTS exhaust resonators. Probably wouldnt suit me or the onlookers, but who knows.
Great products get even better with time!
Maybe some nitrous next......

Hey guys thanks in advance for your help!
Anyway, the shop is installing my PPE headers right now and just called me and said they don't do welding and were unaware they would need to weld the magnaflow cat's that are optional with the PPE headers into the system. I REALLY LIKE DV8's setup and wish to copy it. I know that the flanges will need to be welded to the Joe-Z exhaust tubing and I'll need to take it somewhere else to get it done. I've just been searching online and found these V-Band clamps....
http://vibrantperformance.com/catalo...roducts_id=155
Will these work? (I need the 2.5" ones for the Joe-Z exhaust right?)
I'll need to buy 4 to replicate DV8's set up correct?
Also, I know this seems obvious, but I just want to make sure before someone destroys my Joe-Z exhaust, but the shop will need to cut a section out of the Joe-Z exhaust ahead of the Oxygen sensors to fit the cats in there right? Also, will I be able to use the pipe section they cut out, to weld flanges to, to use on track days? (It looks like DV8's using a different piece of pipe.) Thanks again for all these Newbie questions!

We cut the X pipe a few inches down from the header collector flange.
The piece cut out ended up being cut up for testing, so he made up the test pipes out of aluminized. That stuff costs nothing and welds easy. The new angled o2 bungs were installed right after the cat flange as seen in the pic.
