Is there still room to put the stock cats back in with these headers?

 

My pacesetters sound like there is a leak under acceleration. Like a tinny sound. I open the hood dont hear anything, and dont see any discoloring from the flange, but it sounds like a leak. Is that just the way longtubes sound?

 

mine does the same i check all the bolts three times and the 02 sensor's but they are all there. mine under full throttle at about 4k sounds like a 1000 pound cat trying to caugh up a hair ball- i love it expecialy when it blows in the window of the little ricers

blue 01 i wouldnt run cats unless you have to

 

Glad to hear it. My truck pulls alot harder in second gear now. especially over 3000rpm

 

I'm waiting to get mine in and I was wondering how much louder is it without the cats?

 

Mine is louder, but not all that much louder than before. My truck was quiet to begin with because of the big borla muffler I have. Ill be switching to a 14" magnaflow soon .

 

mine seems to pull alot harder all the way through used to above like 4000 it seemed to fall off now it still seems to pull. yeah mine is alittle louder before on a scale of 1-10 it was about a 5 now it is like maybe 7-8 not to bad but i love it so do all the f-body's that helped me install really love it, not normal for a truck around here.


hey dub who did you sig pic? i would like to have one done similar but with the word

Adikt in it and a small logo of yours for hooking me up with the parts. also i am going to order a bottle guage payday

 

hey guys - wanted to chime in as well. got my pacesetters and y-pipe in yesterday. luv that tinny header sound. it actually quieted mine down considerably. i have the magnaflow 4x9x14, 3"/dual 2.5", and it was way loud with the manifolds, and rasp out the ***. now it is actually kind of quiet and no drone. i didn't lose anything down low and definately gained up top. definately a thumbs up for the pacesetters. now gotta get hpt to tweak the tune.

 

i am going to make a trip to the man allen in a few weeks for a street tune and if all goes well i will dyno before the tune and after/ with the nitrous

 

Yeah, your truck does have that hairball sound. Kinda hard to hear over the chick in the Cavalier screaming "we don't want to race you."
