    I will look as soon as it stops raining. I believe it is a full hole. It was hard to get on.

    I hate to admit it but it has a cheep exhaust on it, a milltek copy. When you take it to red line it use to spit fiberglass out the back. That has stopped, I think it is all gone. OBX headers and stock cat.

    There is a muffler shop I use the guys there are good. I may order a cat and good mufflers and have them build a exhaust. I trust them to do a good job. I believe it will be cheeper to do this then order a full exhaust. But I would like it to be as good or better then what I can order. Cash is tight right now. I still have my stock exhaust, from the cat back, I could put back on but I really don't want to do that.

    Also I want to give Chat at Detroit Tuned a shout out for the time he took on the phone with me. We have some great sponsors here.

    Yep, I think "look at flex joint" is good guidance. But, if the flex joint goes, you can usually hear it. Makes the car sound like a tractor.

    Rule of thumb without a header, exaust or head work is one psi per % of reduction from stock...
    So a 15% usually flows 15 psi, a 17% 17 psi...a bit lower in both cases with a header, cam, or head work...
    So 14.5 psi with a header might not be bad, especially 800-1000 msl...guessing 17 psi -1 for elevation, then a bit for a header..So I'd guess 15 psi would be right, 14.5 is certainly within the range I think...
    I suspect your cat is ok... Folks usually see very high psi with a melted/blocked cat...
    Me...I'd weld the up the exaust for the $50 if $$ is tight, and do it once later when $$ is less tight...
    Heck..folks even do OK with welding cracked cats when they need too if the welder is good.
    If the belt is more than 1 year old...might be time...at $25 for a belt...pretty cheap.

    I would look at the header first....
    Look at the flex pipe or slip-joint if so equipped...
    When the motors moves (the stock mount let's it move more than should be allowed if you have a header) the flex pipe (just a spring like piece of metal with a woven metal cover) fails..guess the hot exaust might be blowing on something making the smell...
    The 14.5 on the boost gauge... Has it changed?

    not sure I didn't look at the boost till this started. After I posted I talked to Chad at DT he said maybe a cat going bad. To also check the belt agin and clutch.

    So do you see one full hole extending on the metal tensioner tab beyond the body out of the spring?

    Do you have the 060532 or 060529 belt?

    Ok I have one hole hole showing.:D On the SC belt. I climbed under the car and found that my resonator has a crack where its welded to the pipe.
    So my options for now are take it to the muffler shop and have them re-weld it, although I fear it will brake agin. or put my stock exhaust back on it. I hate to do that and rob power.
    At least for the next few months I can not order a new exhaust.

    Still sniffing out the smell.

    I am at 340ft MSL but I may not be far off on the boost. When I get back home I will have it welded. The belt is only a few months old. I took my wife for a ride she said it did not smell like rubber to her. as soon as she smelled it I pulled over and opened the hood. I could not smell any oder coming from the belt.

    Nathan I sure hope its not a Cat. That would be bad. I have checked all 4 of our cats are accounted for. :D
