GenVibe - Community for Pontiac Vibe Enthusiasts

I have a magnaflow exhaust, but I haven't installed it yet. My question is it worth buying a new air intake system? I am looking to increase performance, I'm not concerned about sound. I read articles on genvibe about a vibe GT that was dyno with injen CAI first then with magnaflow exhaust. There was a good gain with the CAI but minimal with the exhaust, do you think the same would be true in reverse? Would it be worth my money to buy a new air intake system, buy a different filter, or do nothing at all? Please let me know what you think. Thanks!

well its always good to help your engine breathe better (aftermarket intake) and it most defiantely wont decrease performace by adding it on with the exhaust...it can only help performance.

A CAI is definitely worthwhile. You should get about 8HP gain. Also with a CAI and Magnaflow it will sound great.

Thanks!I don't know where you found that dyno, but Magnaflow's own dyno chart on a Matrix XRS shows a max HP gain of around 7 HP.

Thanks for the imput, I've made my decision and I'm going to go with the magnaflow and the injen cai.

Nice choice. That's the same setup I have right now as well. It's sounds and performs great.Inder
