after doing some things to car like gut cats lose fan , go direct fire , every thing was fine untill the cat gut know im picking up what i percieve as a ever so slight cruise chuggle like its a lean surge, but its so faint i wouldnt notice it iff i never drove it before, no vac leaks runs perfect in all other aspects, does it need bigger jets? are they even available if so from who? thaanks trev

um...gutting ur cat is so not a good thing since u can get more backpressure from turbulance in the flow...well, atleast on my 240 thats wat happened...

 

in my experience, i have found that a header with no cat works much better or a hi-flow cat from catco.

 

thew whole idea was the fact i could do it fast like 30 min , it ended up taking an hour , i like it . im looking to buy header soon so i can get rid of TR and airpump, cause i need that spot for my alternater since the eaton m90 is going to sit where the alt on rats nest are, im starting to drool now.
