[QUOTE="OveRBoreD, post: 13641166, member: 145664"] I'll be finishing up my mbrp v2 race catback tomorrow, complete 3in. Got rid of the factory 2.75 neck downs. I'm hitting 6.5 psi now with the stock h-pipe and the race catback (long story short couldn't get the x-pipe to fit so I had to modify it). I'll let you know what mine does without touching the BC. I have a feeling boost will increase and spool time will definitely decrease. I ran open downpipe for a couple days and it definitely felt like spool was quicker so I couldn't see why or how this would make it worse. Didn't get a chance to run her out open DP though to see boost increase. [/QUOTE]
