My boost gauge is acting differently. It now sits on the 8 o'clock position and jumps up at very little boost. When I slightly hit it it goes up to like 3-8 psi very quickly and when I am in full boost it goes up to 10psi. Very weird just started doing this yesterday, but the car does run...

Just thinking of selling my 03 terminator for a 94-99 Saleen S351. Which mustang could I get more everyday reliability from and be pretty quick on the street too? - 4.6 with kene bell/ whipple on pump gas = 560-650 rwhp. - 5.7 done punched to 408 with aluminum heads and bigger vortech=...

I currently have a steeda 2.9X pulley on my car and when I had it tuned it saw 14psi with stock manifolds/ high flow cats and bassani cat back. The car made 492 rwhp,499 rwtq. I now have mac longtubes/ o/r prochamber and stingers with the same pulley and the car made 496 rwhp, 500.2 rwtq...

I have the mac longtubes/ mac prochamber with the stingers and just wondering what would be the difference if I installed the new Mac X pipe in place of the prochamber?? Would it be louder?? What kind of tone would the X pipe give over the prochamber?? Any input would be appreciated.

I just had mac longtubes installed on my 03 cobra a couple of weeks ago and am stuck with an exhaust leak. The speed shop that installed them (actually has a good reputation of doing a good job) won't admit that they messed up and won't want to do it over. They told me that they re-used the...

Just had my mac longtubes put in with the off road prochamber and borla stingers. Kind of disappointed in the sound, it is very mellow and only wakes up at around 3,500 rpms. Thinking of putting a Dr. Gas x pipe to replace the prochamber, any suggestions?? I do want it loud at idle and across...

My 03 cobra was tuned with 490 rwhp. 503 rwtq. with the chip/pulley/cold air intake. Couple of months later I decided to put an o/r prochamber and Flowmaster 3" cat back. From the cat-back I realized that my low end felt weak, not as responsive. And when at wot the car just hesitated and...

The flowmaster cat back with a 3" tubing. Would it be more ideal to get better flow and sound if I weld a set of 3" spintech pro street or just heck with it and buy the a used cat back Stingers. Looking for loud deep sound and most importantly better flow#. Which would flow better...

I have to save up for a decent exhaust and want something loud, aggressive and deep. Which one of these cat-backs would give me that with an o/r prochamber ? I currently have magnapacks welded into my bassani cat back and it is not as loud and deep as my 2"1/2 mac cat back I had on my 04 GT...

Is there anybody running these springs on their cobras?? They are part#3594.140. I got stuck with the wrong ones Part#3590.140 due to Lethal Performance and Eibach and am looking to see if the new ones are worth it. RPM Outlet is selling them for $199.00. Any feedback would be...
