Thread: Stupid ZZP DP question driven by paranoia

The exhaust itself isn't restrictive past the the ubend area but your eliminating that w/ the downpipe. The rest flows just fine till about 300-350hp then that's when it debatable that it becomes restrictive. Most will never reach that point.

Most would just do headers and leave the rest of the exhaust alone unless they're going for a different tone

What I would do is leave the stock exhaust if your wanting a better tone just cut off the stock mufflers and replace w/ (insert brand of your choice) and have them welded on. Saves you a bunch of money and the ZZP exhaust is excessive loud... I wouldn't go that route you'll need up hating it quickly

Mind is at ease, ty.

Yea I don't want ZZP mufflers, loud/rasp/drone would NOT make me happy. Just want the option of buying a complete 3" cat-back setup perhaps from Magnaflow or the like.
My resonator on my stock cat-back atm is leaking like crazy and needs to be cut out and straight piped. The flanges are prolly corroded beyond use too. I'm gonna hunt around for a set of pipes and just pair up some Borla Pros with them. Might add a res later if the sound is too much to bare.

Replace the res with a glass pack, cutting it out and deleteing it will make it raspy.

What will the glasspack do to the sound? Any suggestions where to get one, I've never looked at packs.
I like the way the Borla Pros sound on these cars. They have a pretty low volume (amount of sound put out, *like), but a nice relatively deep rumble that sounds just a notch above stock. At least in the clips i've seen.

Borla xs pro, stock resonator is what I ran for a long time and loved it.

Off topic now, but if you don't mind.. know what part number mufflers you had? Here's a couple I was looking at on Amazon.
Borla 40358 Borla Pro XS Muffler
Borla 40348 Pro XS Muffler - dual outlet, the previous is probably the better choice.

Aha, so close. 40357 it is, thanks.
Now just to cough up the $180.....or scower craigslist for awhile.

Do you know if the stock mufflers are welded on by chance? I'll just look tmrw, but it's 15 degrees out I ain't running out now aha.

Yea I will probably do the same. The saw blade is prolly $10 anyways. And I definitely don't know how to weld or have a welder.

So when I made this thread, I also sent out an email to ZZP. Just got a response.

The downpipe you ordered has a 2.5” exit, so you need either a 2.5” catback, a custom 2.5” inlet on a 3” catback, or to send the downpipe back in so I can put a 3” exit on it.

But from what we've talked about, there's no point in me going thru the hassle of sending it back or even getting a 3" catback until ~350 whp? My intentions atm for my car are a 3.4 setup. Probably will stop there, at least for awhile.
