So I have a little extra cash and was thinking about what things I could buy for the GP that would help performance. As of right now I only have a GT but I'm planning on doing a topswap this summer so figured why not get some supporting mods. I don't have a ton of cash so I'm going to wait till this summer when I can pull in more hours to buy all the topswap parts. I've read the safely modding your 3800 thread and the topswap thread which is why I've decided on a downpipe. My questions are...
Staying N/A for a little while will a 3" hurt or is it fine?
I've read that going catless gives a better tone so i'm going to do that. On ZZP I'm guessing the off-road pipe is the catless? Also does going without the cat make it harder to install?
On ZZP there are a couple different options to chose from before buying that I'm not so sure about. Do I need a rear O2 bung if I'm going with the off-road pipe? And do I need the front and rear gaskets?
And my last question is buying the downpipe does that solve the u-bend problem or would I have to buy the U-bend delete part?
Sorry for all the questions all at once I'm just new to the whole car modding thing and trying to learn. Thanks.
