I think there will be very noticeable power gains with removing the cats. The cats really clog up the air flow coming out of the engine. Once the cats come off your engine is gonna breath so much better and be able to push that air out way faster. Air out faster, creates more HP and torgue to engine. My cats will be coming off next month along with headers going on.

Yea... I was just thinking, maybe just doing cat delete would be the way to go VS spending an arm and leg for long tubes.... Or maybe I'm just cheap lol

No way man. I feel ya. ***** can be costly. I think just having the cats off will be a nice difference for ya. Modding can get costly. I just bought a one piece aluminum driveshaft and 3:73 gear combo kit and there going to be installed this Monday. Between the two purchases it was like 1.3k with the install.

I hear ya. I just put springs and pan hard in today and I'm trying to pick a DS now but I'm not sure what to get. I did 3.73's about a month ago and love them. I was thinking about going with long tunes but if I just do deletes then I can get my in dash screen that I have been wanting...

No sir. No way would the removal of cats pass your inspection good sir. If you have inspection then your best bet is to go with high flowing catted x pipe.

Newer models free up more than later ones obviously. But depending on your state laws you wouldn't pass. My inspector didnt look under it. When he was working on it it threw codes cuz I don't have eliminators. But he now knows why it throws code for o2 sensors. But he passed me before he saw I had no cats

[QUOTE=Adogg;1546993]Yes I still have mufflers 10 series!!!!! [COLOR="Silver"]

How do you like your 10's? I have been thinking of getting some...




Anyone know the specifics on the NMRA "Super 'Stang" class? All I could find was that for NA cars (that would be me) you have to weigh in at 3200 pounds, run a 14.5 or better, and launch on foot break only.... but there has to be more to it than that. there are power adder regulations as well but it looks like they just need to weigh in at 3400 pounds? Cars will stage with a 0.500 pro tree (no idea what that means) in a dial-in-style race. foot break rule applies to all.

Im good to go as far as safety equipment i think. I have safety loops going in with my DS as soon as I get a chance to instal so if I break into the 12's I wont get the boot. Im pretty sure I can get the 12.99 now if I can get hooked up, time will tell. Im pretty new to the "official" racing scene. I have been to enough open track days but never anything official. It would be a real shame to show up to my first real race and never make it past inspection so any advice or pointers are greatly appreciated...
