i have a bad mab header and zzp 3 inch downpipe i just put on 2 weeks ago and i keep blowing out the flange gasket. i have tried every gasket out there and nothing seems to work. anyone had this problem before or no what the problem is?

 

warped flange?

 

i put mine in, idk... 7 months ago. i have bad mab. zzp catted dp and corsa catback. absolutely no problems. i used the gaskets that came with the dp not the bad mab garbage gaskets ha

 

This.

I've had the Badmab header on my car for close to 8 months now w/o any issues. When I removed my catless downpipe the flange gasket fell apart. I installed my original gasket from my stock downpipe, and everything has been great.

 

Mine sounds like it leaks when I start it up and when i floor it. I don't know if it's a leak or just a raspy noise though.

 

Did you try re-torquing it after the first heat cycle?

 

i find that its hard to get a supercharged 4 banger to not be raspy at WOT.

 

x2. i put in a bigger resonator and went thru 3 diff mufflers before i found one that didnt sound like complete shat.

 

ha yea i did alot of research to get the best sounding setup i possibly could i lovvvvee my setup ha. but i cannot STAND how it sounds when its warming up. idk if u know wat i mean. like i get outta work and start my car. sounds fine. then i start to drive and the second i hit 2500rpm it gets raspy as **** ha. annoying. but once it warms up its not raspy except on WOT. ha and that doesnt bug me much because im more interested in hearing the supercharger ******* screamin

 

The Corsa Touring catback produces zero rasp at WOT.

I've been running it on my car for 1.5 years now. Love it!

Also, the GMPP catbacks sound wonderful as well.

 

everything is brand new so i dont think its warped but im going to order a new gasket from zzp and try it. its blowing out on the bottom of the flange at wot so it might be a backpressure problem with the stock catback

 

Sounds like its flexing too much.

 

ha im pretty sure my setup is identical to yours. it rasps quite a bit. but only at WOT

 

Well, mine doesnt rasp at all (cruising, part throttle, wot). So I don't understand why yours would be any different.

I was catless when I shot this video. I went back to a catted downpipe this year, because I got sick of the smell.

 

i have same setup id say warpped flange or maybe get an oem gasket remflex makes good stuff

 

weld dat hoe down yo

 

I have a remflex gasket installed at the 2-bolt connection flange for the downpipe & catback. It's a great quality gasket, and it's leak free.

For everyone claiming they have a leak with the Badmab don't put it past the ZZP downpipe as the cause either. I had a ZZP downpipe back in the day, and it had leaky flanges.

 

same as the cobalt addiction dp. first day i installed it it was leaky even after putting in diff gaskets.

 

I have zzp midlength header/dp and its warped. Is it possible to just cut off the header to dp flange and weld it?
