downpipe too short by 1 inch!

[3p141592654]

I finally got around to installing my 3" downpipe and elbow, and have run into a problem at the connection to the front of the cat. The downpipe appears to be about 1 inch too short, so that when I bolt it to the stock hanger/cat everything gets pulled forward and up, and fitment is poor.

Question: was there any change to the position of the front hanger/cat flange over the years (I have a 90T), or is my downpipe length faulty.

wait i dont know if your talking about what i am. but on diffrent years... arent the cats diffrent sizes... when i ordered my test pipe there where 2 sizes?

Your downpipe is faulty most likey. what brand? I would just take it to an exhaust shop and have them either extend it, or if you can find a cool shop, have them makeyou a 3" test pipe.

its a sign to upgrade to a custom 3 inch straight piping . Seriously you can do it undr 100 bucks heh

Worried about fitments and lenghts and parts being faulty, I just made my own custom 3" piping. Works like magic.

Would you happen to have a Blitz Nur Spec catback? They are about an inch shorter...I think they were fabbed for a 1J???

Read my mind I've got a Blitz and it is in fact about an inch short.

are you sure about that? My blitz nur spec was an inch too long so i had to get it cut

Yeah - pretty sure. I installed it before I replaced my downpipe several years ago (one of my 1st upgrades) and had to pull the piping to the CAT. Had to replace a couple of stock rubber hangers with the donut type to get it to work. I'm starting to think Blitz may have some quality control issues...:3d_frown:

Why not take your car down the street to one of those muffler and tire shops and let them relocate your hangers? I figure that would be the cheapest fix.

Thanks for the help everyone. I have the HKS Turbo D2 cat back and it connects fine to the stock cat/downpipe setup. The new downpipe is shorter such that if I connect it to the front cat hanger it is misaligned by 1.4 inches to the hanger on the body. My options seem to be to make a 1.4 inch test pipe!!, or get a new downpipe. Its a cheap Pipe Line downpipe from ebay so I think I will dump it and get something better.

I'd keep the downpipe and make a 1.4" test pipe as you mentioned. Or just have an exhaust shop make you one then take it home and bolt it on. No need to scrap the downpipe just becuase it doesn't say HKS on it.

I ran into the same problem with my HKS super dragger. I had to order my test pipe an extra inch longer than the cat for everything to fit properly.
