got my downpipe situation figured out. had a bad gasket from ZZP after 3 days of driving but i got it fixed yesterday. sounds awesome with my GM exhaust. i couldnt find any other vids on youtube with the same exhaust and the K&N SRI so i decided to make a video.

bumpp

 

Glad you figured it out. I just figured mine out yesterday too. Broke flex pipe. Just ordered a zzp. Lol. Hopefully this one is better quality than my last one. Sound good btw.

 

yeah i cant believe monroe told me the flex pipe was bad.
the zzp gasket was so bad it was crazy

 

Too bad your not 5 speed or tuned.I'd like to hear it over 4000rpm.sounds good though.I love my ZZP DP

 

i know. yeah im auto. but it still sounds good.
and i gotta get a header and install my 2.4 stuff than a tune. i cant wait to see what it sounds like past 4000 rpms

 

stab the throttle to the floor and it will rev out to almost 5k before it catches your throttle back to 4k

 

it does that SOMETIMES. but to like 4300 thats it

 

Gotta be quick

 

lol never had it go to 5 4300 was most i think
