I am preparing an outline on my next project, the exhaust.
Currently i have everythin stock but for the muffler which is a magnaflow.
I have a 5sfe, 99gt

What i am looking to do
1. Replace my cat with a high flow cat(any suggestions)
2. Replace the downpipe(from the cat) with a 2.25" mandrel bend
3. Re-use my magnaflow
4. Remove the resonator

I am no expert on exhausts and hence need suggestions from you guys..
Also, is there anything i could do to the midpipe.

Thanks,
Preetham.

i don't know about your other parts but the resonator is the easiest it's just a cut it out and then weld in a new straight pipe
i just had that done on mine when i got my muffler done

yes, i guess while replacing the cat back, i can do away with the resonator..
I want to know, what high flow cat i can use, how much will it cost, and how will it afect performance and inspection...
