No need to be embarrassed...just lurk the for sale section and eBay for a 3" CAT back. Probably be able to pick a good one up pretty cheap :naughty:
How much boost should I have? Only 7psi?

not sure how any of your mods would increase boost....stock boost = 6.8 psi. sounds like you've got a good working WG....get a MBC and crank it up!
I never installed an aftermarket boost gauge so every number that I put will be from the stocker. When I was with a stock intake/exhuast setup my gauge showed 8 PSI. When I put on my HKS intake and 3" turbo-back exhaust with no cats my gauge would peg out in 3rd-5th gear. I don't know how much of an increase that is because 8 is the highest number on there. lol But when I got my wastegate shimmed, my boost would jump up to 6PSI and then peg out every gear. I love it.
On the note of the exhaust volume, mine is damn loud. I have the RSR catback with no resonator. Very sweet sound which isn't too bad in the car but I've had a few comments from people around work and home. One of the guys from my shop has a 3" exhaust that's very discrete. He has put a 3" resonator to quieten things down.

jdub said::withstupi The operative word here is "slight"...and Nick, you're not stupid
On a stock CT26 (not shimmed or no MBC), the most boost I ever saw was ~6 psi...the intake, Defcon downpipe, and 3" CAT back exhaust on my former set-up did increase it "slightly".
On mine, (full 3" DP and cat back w/dump, custom intake w/Apexi filter, FFIM, 2.5 IC pipes, large real-SPEARCO core bar and plate IC, stock rebuilt CT26 w/NO boost controller, NO shimming of the WG, [see my build for details]) I'm hitting between 10-11 psi. So you can see more than "slight", but I don't think it can happen with the stock layout and/or old high mileage turbo and WG.

Read his 1st post...we were talking about a basic set-up. Your set-up is far from basic
I'm pushing 20+ psi out of a SP61 with upgraded intercooler & hardpipes...that's why I didn't use mine as an example...apples vs oranges.

My point was stock CT26 with no controller or shimming and relying on the stock WG. Sorry if I missed the point
idk... with intake, crush bent 3" exhaust, and pvc ic pipes, i was seeing 10-12psi regularly.
With open DP, I was hitting 15psi, and fco.

go and slap your welder, and demand your $ back :biglaugh: ... i was able to do my exhaust w/ out a hitch... in my friends front yard... the muffler on my car is mounted where the "test pipe" would go, or at the end of the downpipe... there's plenty of room :-/LouKY said:
Kurt-
you would only get a CEL from a boost leak if it was bad enough to trigger fuel cut.
i dont recall- do you have an aftermarket boost gauge? the stock is ballpark at best. aside from that, it sounds about right. youd be surprised how restrictive the elbow itself is. i have a ported stock one, we should throw that on your car next time im over.

Dave, I've got the stock gauge, but I do have a new elbow on there - I believe Jon made it, and it should be a big improvement over the stocker. I appreciate your offer.
After everybody's reply, I guess I realize I was showing that I'm still learning a lot. It seems pretty obvious now that unless the wastegate is shimmed or a MBC is used, then boost will have to be limited by the wastegate. Noted, learned and filed for future reference!

ROFL, I was reading page after page waiting for somone to say that, and when I dident see it right away I thought I was taking crazy pills... You need to adjust your wastegate via BC DUUUHHHH!! Get an aftermarket boost guage set BC at about 10PSI and you should notice a HUGE difference!!
IDK... I've seen numerous people gain boost pressure simply by putting a DP/elbow combo, one piece DP, or DDP on.
