MBRP Street Dyno numbers?

[watchdog]

Not sure about more power, but it definitely more noticeable at WOT. FYI, have almost 2500 miles on MBRP street and it's gotten deeper, less raspy . Could not imagine driving this car without it and the extra 1 HP.

Def worth it for the sound

Yep. Mine has about 5k on it and a couple thousand ago it started to deepen and the rasp settled down. I was iffy on the rasp at first, but I got the catback very gently used for $400 so I figured it was worth a shot. I can't be blowing a grand on something that I bought purely for sound.



I didn't think it was getting 28-29 more, and especially with the joke Gibson's numbers have become around the forums. I just always sit there and wonder how these companies can tout these incredible gains and get away with it. Shouldn't some governing body be involved at this point? LOL

Or maybe they do their dyno runs with pure oxygen being blown at the intake? ;)

Sure doesn't feel any stronger. But the more miles the Street gets on it, the better it sounds. I'll give it that.

watchdog or PJR, do you have any videos with the broken-in mufflers? This kit doesn't make the greatest first impression, and people take a hit by swapping before hearing the real sound.

Mine hasn't changed that I can tell with 6 months and maybe 8K on it. Hit 4K and WOT and it's raspy as F***....sometimes it seems worse than others, sometimes its just god awful but I've gotten used to it.

Mine felt slower after the Corsa Xtreme install. I can likely attribute that to a power band shift going to a 3 inch exhaust.

More then ever before, these mods are small (and expensive) contributors to the over all picture of performance. These modern engines are super efficient from the factory. The days of cheap HP and pushrod 302 small blocks are over (for us lol) We either have tooth and nail mods or spend the dough for the easy power adder gains.
