Did you have an L99 on both?

No, bother were M6 cars, both 100% stock prior to puttin on JBA catless midpipes and a SCT tune to turn off the rear O2's. The 2010 was much louder and "crackled" on decel much more than the 2013 with the exact same midpipes. Thinking there must be a difference in the rest of the exhaust on an M6 SS car between 2010 and 2013 to quiet them down... or a SCTx4 tuner tunes out decel pop whereas the SCTx3 i used on the 2010 did not. Was curious if anyone knew why the '10 would be louder.

I learned something new today!

resonator delete

[QUOTE=Shaun SS;4259543]I've got Magnaflow Catback Exhaust, but I want louder.. Is resonator delete a route to go?
One place quoted me 150 the other says 750 lol.
Will I have a check engine light come on?[/QUO

When I had a X-pipe installed,it deleted my resonators and with the Borla Ataks

Very true. From all the research I have read, H pipe will scavenge at lower RPM's better than a X pipe. So if you want stop light to stop light power, than an H pipe is for you. X pipe works better than an H pipe at mid to high RPM's. So if you are tracking or want to just blow someone's doors off on the highway, than an X pipe is for you. Then there is the sound tone of both depending on the rest of the exhaust ( straight piped or performance ) which may also way in on your decision if you just want a different sound. There is also where the crossover pipe is placed as it will play a key roll in timing of the pulses. I've seen some x pipes welded up near the mufflers, this is a mistake. It needs to be closer to the headers for proper scavenging. The H pipe built into my stock 2SS resonator was closer to the front than the back of the car.
