Alright fellas, I recently swapped back my stock axleback muffler but still have my aftermarket header, and exhaust piping. I was wondering instead of buying a "quieter" muffler would placing a "small" gap between the axleback decrease backpressure?

I was thinking it should because now the gases will be exiting from this gap as well as the muffler. Or will it actually hurt the performance because the leak will cause turbulence?

Just trying to find an alternative to something that flows better than a stock muffler but quieter then an aftermarket muffler.

Any insight would be great.

Thanks
