Thinking of putting on some Kooks 1 3/4 headers X pipe and cat back. Any recommendations on a good exhaust shop in the northwest Oakland/NW Macomb county area?

Was just driving home down a pretty open two lane road and a BMW comes up to me with the usual loud BMW exhaust sound. I typically stay away from street racing but it was later, the road was ride open, the temps were cool, so I figured what the heck. I've raced a few BMW M classes before...

I have a 2013 Shelby GT500 Race Red with White Stripes. Is it okay to use a clay bar on the stripes, or will it damage them. Do I need to be in the shade, or is it much better to do in the shade?

I have a 2013 Shelby GT500, mods in my signature. I've seen a lot of videos on people running E85 or "corn" in their Shelbys, what are the pros and cons of doing so? I know you have to have an E85 tune, but is it a complicated or difficult process to switch to E85? Thanks!

Mods are in my signature. Current exhaust is stock minus the cats. I'm running about 650 whp and working with Lidio over at Alternative. Once spring hits, I'm going to have him put in the new rear end and will most likely go with 3.73s. I'm also going to talk with him about what it would...

high octane fuel? Edit Meant Turbo Blue 110

I cannot get traction. I know with this much power (648 RWHP) I'm going to struggle anyway, but it seems like even in 2nd gear I'm struggling to get traction. The tires are practically brand new, so I'm not excited about spending money on 4 more new tires, so could I simply swap out the rears...

I have a 2013 Shelby GT500. Mods are as follows: Whipple CAI Whipple Twin 68MM TB Metco 2.4" upper pulley Metco Auxiliary Idler Kit ARS Belt Tensioner NGK plugs Tuned by Lidio at Alternative Auto I dyno'd 648 RWHP and 620 torque. Was kind of disappointed in the torque numbers but Lidio said...

I saw him at a party and his brother told him about my Shelby and he said he would take me all day. His Corvette is stock, I know it's not a Z06 or Grand Sport, but I'm not sure if it's one of the other performance packages, I didn't ask. I told him he'd take me from a dig, but I believe I can...

years. My 2003 LX Convertible. I used a car cover then and for the first time, after storing cars for years, I had an issue with mice getting in and doing what mice do. Chewing up wires, shredding sound deadener etc. I'm hesitant to use a car cover again, and since I'll have it on a tender...

The ones on the front and rear are a bit nicked up and I’d like to replace them. Are they easy to do yourself, or should I have a good body/paint shop do it? Thanks Sent from my iPhone using the svtperformance.com mobile app

Seems like an incredibly low price. Looking at the carfax they supplied it's a one owner call with no accidents. Any other vert I've seen like that has been at least $5K more than that.

I have a 2013 Shelby GT500 with black recaros with the white stripes. The white stripes are a bit dirty/dull so I'm looking for recommendations on what to use to clean them up. Thanks!

Trying to get the new ring and pinion and the tuner said it's some kind of a unique spline drive on all of them and he doesn't have that at the shop. Adding a picture for reference.

Even when I'm at a stop and switch it back to Normal, as soon as I start moving it flips over to Sport. Then when I'm driving and come back to a complete stop, it switches back to Normal. Is a damper stuck? Is it something with the electronics which seem to have multiple gremlins?

Scanner says P0420 Catalyst System Efficiency below Threshold (Bank 1) and P0430 Catalyst System Efficiency below Threshold (Bank 2). Does this mean I need new cats? Exhaust leak? I'm taking my car to Alternative Auto Performance on Monday the 24th, is it possible the tune isn't correct and...

Anyone have any issues with this? I have a newer garage door opener, 5 years old or less. Followed the directions but it's not working?

Hey everyone, I got my 2013 Shelby GT500 about a month ago and I was out driving tonight and came up against a C7 Z06. I just got my car and I know I'm playing with fire a bit because I haven't had it to a tuner yet, but I couldn't resist. I'm going to set up some time with Lidio at Alternative...

Filled it all the way up but did NOT top it off. Soon as the hose clicked off, I removed it. When I started it up the check engine light came on and went to O'Reilly's and scanned it and the PO443 code showed up. Is it the Kroger gas, LOL? Filling it all the way up? Both? I'm fairly...

I just bought this car a couple weeks ago and another gremlin has popped up. It came with two car fobs, one was barely working, and the other while it worked, seemed kind of weak. Could that be the issue? The lights come on fine so I don't think it's the battery?

I'm learning more and more about my new to me 2013 Shelby including how loud it is in the cabin. I'm not worried so much about the exhaust note, it's a stock exhaust, but the road noise is pretty loud and very annoying after a while. I'm running Nitto NT555 G2s with 285/35ZR20s in the back so...

Hey everyone, just bought a 2013 Shelby GT500 with about 26K on the clock. Just got delivered yesterday and took it out this evening and drove it around and got on it some. I noticed when I pulled in the garage a slight, but not strong smell of anti-freeze. Has anyone ever had that? Any help...

Hi everyone. I'm new to posting to the forum and looking to purchase a 2013 or 2014 Shelby GT500 Convertible. Looking for relatively low miles, under 35,000 and either no modifications, or lightly modified. Looking for black with white or gray/silver hood stripes, or Red with white or...
