oh and you'll likely get a check engine light the first time you get on it at all. that test pipe is resonated but wont do much for the secondary o2 readings. in that event just get one of these:

i got the same thing for my car and have never had a problem

 

i was trying to take the downpipe out with the stock cat still attached to the dp since i was installing a new downpipe/test pipe combo

oh nvm..im an idiot..i thought id be able to get it out without remove the control arm braces...

im gonna go take that off right now and i should be good to go

 

ok so i finally got the dp out, bolted the new dp and test pipe in..

but now theres a 2" gap between the test pipe and my catback..

what do i do? just pull the rest of the exhaust back under the body a little bit?

 

no big deal, the catback is just hanging alil away like a pendulum. just pull it back and bolt it down.

 

40!!?? that's a lot!

 

ok ok ok 40 is generous,Maybe 40 with all the stuff i have. The butt dyno says 40 but who knows on any given dyno it could be 20-40whp so who knows, not tryin to spread misinformation .

But a tune and a free flowing exhaust does wonders is what I am sure of.

 

also when we were taking the dp off the hangers, the two bolts broke...

right now im not using the hangars...should i get those two bolts replaced asap or can i go without them?

now my muffler tip is under the rear bumper a little..is that something i should worry about or can i just get one of those shields and be done with it?

 

ok so a couple things...

1. the connection between test pipe and the exhaust mid pipe does not have a gasket between it...should i put one in asap (or can i get some sort of gasket glue stuff?)

2. when i first start the car if i go to the muffler i can hear a faint ticking/clicking sound...whats causing that? is it something i need to have taken care of? (never did it before the dp/testpipe install)

 

i did a search on the mechanical fix but everyone else seems to have had an o2 sensor coming out of the cat, i didnt have one...my o2 is on the midpipe of my catback??
