3" cat back exhaust.......?

[OHstinger]

Please do! It will be very interesting to see real life results. Also, I believe the most, if not all of backpressure comes from primaries. And it looks like turbos need it for proper sealing. There're a lot of reports of leaking turbos, once primaries removed and replaced with free flowing sections.

I have my primary cats still with my system, no secondaries however. My only issue has been overboost on a couple occasions. But I blame that on not being tuned or having a JB4. KSR will most likely be doing a custom ECU tune for me in the summer.

Resurrecting the thread!

How did this turn out? I stumbled upon KSR 3" exhaust and it got me wondering how this sounds.

How is highway drone? Vibrate the interior? Build looks great, everything fit ok being 3"?

Coming up on 3 years with mine and no regrets. There is slight drone on the highway, but if you get tips to extend the exhaust out of the diffuser it helps big time. Definitely loud, but not obnoxious, and like Monarch said, the burbles when you left of the throttle are glorious.

Feel free to check my Instagram account, same name, for some sound videos.

Did you get a ecu tune from that shop?

No not yet, decided to do a bit more cosmetic stuff. I noticed that I really only overboots when I gun it to hard before the engine is properly warmed up. Once it reaches normal temps, I do not notice any overboost. The tune or a JB4 are on the list, just not a priority for the way I drive.

WOW! That’s quite a gain for an exhaust system. I de really like to see those results too. So your are up over 500 hp to the wheels now? I’m jealous
