Just installed my hooker catback
Just installed my hooker catback
Awsome system would sound better if I had a 350 and new headers instead of a 305tbi and stock headers. Just some problems i have right now. I smell exhaust when im driving with the windows down anyone else who put theres on have trouble bolting to the cat, I think thats were its coming from. How far off the ground is the headpipe supposed to hang it seems to be kinda far down? Also anyone else have their tail pipe on the passenger side rubbing against the rubber peice hanging down under the spare tire.
thanks

It sounds like you're hanging crooked. When mine went on, we couldn't make the hanger on the passenger side of the muffler work right, so we pitched it an made a different one.
If the muffler isn't hanging right, then it puts a lot of twisting stress on the cat flange, pulling it out of alignment.
I assume you just bolted it together, and haven't welded the seams yet. If so, it should be easy to wiggle things in to proper adjustment.

yeah i figured it might be that cause it was crooked to the point that i had to use a longer bolt on one of the sides to make it fit to the cat. I'm gonna have fun making it fit cause the bolts aren't long enough.

Just to point something out you don't have stock headers, they're manifolds. The exhaust did a good job on the install of mine. Glad to hear you like the sound.
Well same thing basically. Anyways I just starightend the headpipe and cat connection but I can still smell exhaust with the windows down. I think i might have cracked the y-pipe putting the cat-back on cause i can hear it ticking at idle. Whats the price range for a good y-pipe header combo for a 305?

The ticking also could be where the y-pipe connects to the cat. Make sure its tight, I had the same problem now... only cause I have a 3" y-pipe goin into a 2.25" cat. 
Ill take a pic of the setup now b4 I put my hooker cat back on this week... I think im gonna win the jerry riggin award for this one!!! :lala:

1: How? I'd like to see that setup
2: Why? Why, Why, oh Why?
good price for the header and y-pipe combo is 114.00 for heddman headers and 99.00 for the y-pipe i just got mine about two days ago from jegs and haven't put them on yet (too busy installing the megashifter and tach) but i will let you know how easy or hard it is.
