help! raspy exhaust set up, can the axle back be my cure.
Need some input on my exhaust set up, I recently installed AR catless dps on my pre existing riss racing midpiped/stock axle back. Fully catless sounds great while cruising but just around 2800rpm I am plagued with rasp, it is especially bad while going up hills or under load. My question is I have a Remus Race axle back waiting to be installed, will this make the rasp any better or any worse? Logic tells me the rasp will just get much louderbut im hoping that this axle back will cure my rasp.

I had Straight 3inch pipes from the stock dp back, okay drone and okay rasp. As soon as a installed the AR 3inch dp for a fully catless set-up, sooo much rasp and drone I only drove my car up to 2500rpm and shifted. I drove slow for four days until I was able to put on two resonators. That took the sound back to how I had it.
