Am I crazy?????

I'm just wondering if it's just me, but I put a Magnaflow catback on the 03 last weekend, and I must be crazy, but it seems like it lost power, and it seems like the boost doesn't kick in as quick as it did with the stock system.

I put a Magnaflow on my 97, and I felt the diffrence right away. Plus I'm not sure if I like the sound. It's actually kind of loud, where the one on the 97 only gave it a more exotic sound. The sound may be because I had a Bassani X on the 97 where I just have the stock mid pipe on the 03. I'm going to take it and have it dyno'd Thursday I hope.

It makes power.....I have dyno proof of this.

03 Cobras sound "muddier" or less "poppy" than the older n/a 4v engines because the 03 has lower compression.
Few things sound better than a 5 liter cobra or a 4.6 4v n/a cobra with exhaust.

Notice how killer the 03 sounds though at 4,000 rpm, or after building boost......add some longtubes and DAMN it sounds nice! It sounds kinda funky at low rpm.....but that's low compression for ya.

Get rid of those 4 cats and throw a magnaflow x-pipe in there and you'll feel the power...
