My friend Oldbones used to have a similar setup on his 03 cobra. It sounded super pissed with his cams. Now he has flowmasters with dumps and they just dont compare. God I miss those SLP's
I LOVED the SLP's with my o/r h....until they got real raspy. Idle, cruise, and certain rpm's sounded incredible; but drop the hammer and it sounded like complete ***. If getting a set of the LMII's would take away the "raspyness" I'll take the flows back off. Its a real shame too cause it fit so well and looked killer, but instead that nice catback sits in the shed.
