Pypes w/Hi Flow Cats Idle

Magnaflow w/ No cats idle

The exhaust note is really softened by the Cats on the Pypes, the Magnaflow is more rumbly, but I have no cats on the Magnaflows.

In the Magnaflow video, one side of the exhaust isplugged in one tube on each of the Magnaflow mufflers and it is that loud and the drone was bad unless I plugged 1/2 of each muffler with Stainless Steel Wool

Wish i was closer, heli-arc welding is actually quote simple to do, but you gotta have the equipment
OK, when I put my Pypes cats on and had the car tuned, I dropped @ 25 TQ/HP based on my previous dyno, unfortunately, the dyno results were from 2 different dynos,, everyone says, "you'll drop @ 5 hp/TQ" well, mine "might have or might not have" dropped more because of the 2 different dyno results
so I bought a crank trigger and I will tune the car with FAST sequential injection and with the cats and have it dynoed.
Also, I bought a new X pipe and will dyno the car with FAST sequential and NO cats for a comparison...
My hope is that the Sequential tuning will reduce the smell from valve overlap and allow me to run with no cats as well, and potentially pick up some HP/TQ to get back to where I thought I was.
My car is being painted so I don't have the car and dont anticipate getting it back until mid next week at the earliest, then I will mount the crank sensor and phase the crank and rotor and begin the tune I expect this to be finished by the end of July if my business lets up some
to be continued.....
1. No I don't have a before and after with dual exhaust w/cats and Bank To Bank and without Cats.
Dyno info coming soon.









I like the new sound better.
