What horsepower gains will I see if I replace my stock 2 cat y-pipe with a Random Technology y-pipe with high flow cats. I'm guessing 5-10 hp? I currently have stock exhaust manifolds but will be installing SLP shorties in the future. The RT's will bolt directly to the SLP'S.

RT Claims 10 HP, which really isnt much for the $400 plus it costs. Ive been consideringgetting it for my Z, but I dont think I would benefit much from it till I get a better cam/heads combo. I think youd be better off getting some headers, and/or some 1.6 RR.1996 Arctic White Z28, A4, K&N CAI, TByrne MAF ends, BBK Twin-52mm TB, TB Bypass, SLP 1 3/4" Shorties, Richmond 3.42's, Dynomax Bullet Muffler W/Turn Down, BMR Adj.

Your car and mine are visually the same except that mine is an SS. I'd like to get the same 17x11 rear rims that you have; what is the offset and can I ask what you had to pay for them? Could you send me some photos of the rear end of the car if you have any?
I was going to add the SLP shorties later on when I could afford them; was going to add the RT'S now. I may go with a complete Mac set-up for alot less money.97' SS #497 1 of 50 White Hardtop M6,stock TB reworked to 52mm,SLP CC shorties, Random Tech DC Y-pipe, LT4KM, Taylor Spiro's and NGK's, BMR Adj Lcr's, TA, Boxed SFC's, Adj PHR, Floorpan brace w/ driveshaft loop, STB, GM 4:10'S, 1LE alum DS, Eibach 35mm front swaybar and Pro-Kit Springs, Bilstein HD's, Lou's speed stick with Hurst ball,LS1 front brakes, Earl's lines, Hawk Pads, BMR relocation brackets.Comment

The correct off-set would be 55mm. I paid $1200 if I remember correctly, but that was for all four wheels. Ill take some rear end pictures when I get a chance and send em to you
In the meantime, I have this one.....

I have the SLP Shorties and the RT Dual cat y pipe. The combo works very well and has a much nicer exhaust tone without the annoying reverb of the stock y pipe.97 Z28 Vert A4, TPiS Longtubes, Motive 3.73, Powerdyne 6 psi S/C w/ bypass valve, Mad Z28 PCM tune, MSD 6A, #30 SVO Injectors, custom Random dual cat y-pipe.
