Whats your break down on price and parts? Have you noticed a difference in performance or sound? If s how much? Looks nice.
The 4" to 3" coupler on the TB was from Lowe's. About $6. Filter, elbow, small connector with hole for IAT sensor all from Advance Auto. With $5 Speed Perk and an additional discount code all came to $43
More noise at cold start and wot. Installed a ZZP downpipe last night as well. Runs great. Plenty of pep for an
N/A.

When the car is cold it makes a hell of a noise but smoothed out once you get moving or warmed up. Their is an AC port under my 45 elbow that would make a rattle/vibration after install. I put a small piece of rubber between the two and the noise is gone.

The cat back isn't making you lose power. The downpipe might make a 1 hp difference. The intake probably makes no difference in power.
BTW, here is my homemade intake.

I wish it was. I'm getting the p0420 and the system running lean code. I'm in ca and am forced to pay around 5~600 for a legal one. Might have to go another route..
I didn't read close enough I meant catalytic
I like this one more. In the fender. This write up includes a parts list. Its for 97-03 but I'm sure most of it translates over.

Let's bring back an old thread from the dead....
I'm getting back into GTP's after about 10 years with a '98 Daytona Edition. One of the first things I plan to do once it gets delivered is to do a cone air filter like I had on my '02 (my original setup is shown on page 6 of this thread). My question is: Is there a clearance issue with the '98? I heard that the overflow bottle is in the way but I don't have the car here yet to verify. I plan on using a 9" cone with a 4" diameter pipe, maybe updating to a real carbon fiber piece instead of the aluminum. Any suggestions or first-hand knowledge is appreciated!
