What gains can be expected from a downpipe upgrade? Recommendations?

Buuuump

 

Is the rest of the system stock?

 

ZZP seems to be a good combo.

 

getting rid or putting a highflow cat will give you gains for sure. I can attest to that

 

Megan catback is the only other exhaust mod

 

ZZP DP w/cat and header will wake it up for sure...

 

^^^what hp would I expect

 

No cat for the most gains.......

 

and super loud raspyness

 

why not go for 3" pipping that will give you more space and get you a little bit better flow of your exhuast, giving you a better gain along with whatever else you put on it, like a DP or cat back... unless you already have 3" pipping

 

Because I ordered megan and it only comes in 2.5

 

so all you have to do is go to your local muffler store and order 3" pipping and ask them if they can connect it to your muffler tip and to whatever your going to put on it like the DP or cat back, it shouldn't be that hard for them and it should only run you about a hundred bucks maybe

 

Ya its raspy but it all depends on the exhaust you put after it too. My 3'' catless dp and cti 3" has bearly no rasp to it only when its cold it has alittle.

 

about 10 horse power

 

I ordered the MEGAN RACING CATBACK. Said it a few times actually. Another exhaust is out of the question. I may go with the ZZP downpipe. Seems like a quality piece.

 

I'd venture to say 5-10whp with a 3" Catless ZZP DP

 

you can get the zzp downpipe in 3 in with 2.5 in outlet to matchup with your exhaust

 

From the research I did a while back, I heard that our downpipes were not severely restrictive in comparison to other cars. And it also took like 10 posts before any numbers came up as an issue in this thread haha. Personally I wouldn't expect to see much more than 3-6whp from a dp. Not a whole lot of solid dyno numbers as most people don't go back for just a dp upgrade ya know?

Also good choice on the 2.5" exhaust. It suits us fine unless you intend on pushing more than 250-260whp

 

Don't go ZZP. Sure they're the best bang for your buck but you get what you paid for. They are known to break.

 

Mine never broke and i've never read a thread where they've broke

 

I've read at least three or four in the past week alone asking if it was a common problem. I can't locate the threads right now, but they're out there.

 

just go vibrant header downpipe

 

The downpipe broke or the bolts securing the downpipe broke? The shitty bolts are a common thing. Just need to upgrade to grade 8.

 

What's the best downpipe? Not the combo

 

All catless dp's for the stock or shorty header are going to the same basic thing ,just a pipe....
