        Please correct me if I am wrong, from what I am aware, the only difference between 94 and 99 is the mounting bracket location on the tailpipe and added mounts near the muffler, I would love to mount one of these on my 94, especially since louder systems are now under scrutiny in California, my old stock exhaust has rust holes in it and I could benefit from 2-1/2 pipes rather than pay to replace with stock pipes... 0 answer

          Works for my everyday driver..

          Needed to replace 18 year old mufflers on my daily driver 01 GT. Not to loud fit was good, if your doing this on a car driven in the north be per paired to replace the flange on the mid pipe it will need to be replaced... Pipe is 2 1/4 not 2 1/2. Grind off what is left of old ones most likely not much and your ready two go....

          Sounds great!

          The sound is awesome and overall it’s a good quality catback. The exhaust tip hangers that come with this kit do not work. You have to fab up new hanger to hang the tips. Other than that it’s a good system.

          SR Exhaust

          The exhaust system is descent for the price you pay. The section of pipe that goes over the axle, once install you’ll have to put some wooden blocks under the pipe then lower the car to tweak the pipes up. The two hangers for the tips I had to heat with a torch and twist it 90 degrees to make them work with the hanger kit I bought. The only thing I don’t like is the gap between the bumper and the tips.

          Nice deep sound!

          I have an 04 mach1 and after a cat delete it was way too loud with previous exhaust. So I bought this kit unsure of what to expect, and wow I'm very happy with the deep tone versus the crackle of my old exhaust! Sounds and fits great! Would highly recommend and buy this system again!!

          Hard to set in place

          Its a good exhaust system but the bolts, and everything that come with it are borderline useless... had to weld everything on, and even then its still wiggling and making some noise... Wondering if i should just cut the old muffler hangers off my old exhaust and weld them onto these to hold them in place better because they only come with one hangar for the entire muffler back, and the way the tips are held in with a allen key is useless. everything moves and wiggles under here. and im still trying to find solutions to stop it... im at a loss though it keeps banging around after like 15 minutes of driving... im not sure if this is due to who i took it to, but it overall is what you get for your money. should just stay stock until you get enough for something a little nicer

          Worth the money

          It’s not a top tier kit by any means, but I love the sound it gives off, it’s classic sounding and very tasteful on the ears. I came from having SLP LM1s and I absolutely love this kit! Was a pain to install on stands so I did what I could and had an exhaust shop do the rest.

          Decent enough

          Had to modify a little to fit onto my x-pipe. Hung the tips with ties. Makes my V6 sound like a V8 along with the x-pipe.

          Mislabeled.

          Exhaust sounds good and fits good but the description says 3.5" tips. These are only 3" kinda disappointed. Now I have to order another set of tips separately.

          Easy install

          It was boxed very well, no damage, however the screws that hold the exhaust tip adjusting rod, weren't included. It went together well, you have to twist the pipes in order to set them correctly. It has a nice sound, not much louder than stock, but the pipes are a good gauge steel and the clamps are quality. I'm very satisfied with the product.

          I have this and an H pipe on my 2001 V6 and it sounds decent. Its not gonna sound like a V8 but it definitely wakes it up.

          Fits fine except rear tips

          Everything fit fine except the rods that go into the hangers at the rear of the car. They need to step up about 1-2" and go straight not a 90 degree to the side. I was able to cut off 90 place in a vise then heat with butane torch and ut in my own bends. This added about 1 hour to install. Make sure you support car body and let suspension hang down makes it easier. Fairly quiet

          Tip hangers

          This kit went in pretty straight forward. You have to remove the passenger side bottom bolt on the shock only. The only issues is the tip hanger set up....the long bent hangers that supplied are completely wrong...or the fitting on top of the tip needs to be cut off and turned 90° ...my buddy who is a pipe fitter cut down the hangers (I have a pix of finished piece after modification , can't seem to upload it anywhere )...other than the issue with the tip hangers, great kit..would of taken 2 hours if the right tip set up was included and no custom fabrication was required on the hangers .took 3 1\2 hrs with car jacked up in rear.

          2003 gt

          I was impressed with the quality of this kit! I love the sound the car now. It has a great v8 ton, much more quite than the pypes straight through pypes muffler before. The only thing I had to do to install the tips is weld the bracket to to get it to fit correctly. The best way to install it is to get everything mocked up loose and then move it all around till you are happy with the fitment. Love it! Sr Performance makes a great product for the price just as nice as flowmasters just quite.

          Nice mild exhaust, NO drone

          Great exhaust for the cost, no other axle back in this price range. It's mild, louder than stock but but not over bearing. I say close to Ford's GT500 exhaust on the S197. Zero drone in the cabin. Below 3k RPMs not really any louder in the cabin then stock. If you are looking for a bit more sound with no drone inside this exhaust is it.

          It’s not hard to install as long as you have the tools. As far as sound goes, not too bad. Sound a lot better than stock, for sure. It has a way more deep sound at low rpms. Perfect on the highway, no drone sound at all. Great product for the price.
