    Does the SR kit drone on the highway with the stock H pipe for the GT? I like to change my stock mufflers but also want to have a conversation in my car with a passager at 70 MPH. Thanks!

    I live in Washington State, would this cat-back allow me to pass my emissions tests?

    EthanS

    • Most cat-back exhausts should pass emissions without any issues. With that being said, it can depend entirely on the emissions laws as they vary per state. We recommend contacting your local or state ordinances to confirm what will and won't pass.

      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.

      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.

      SR Performance Cat-Back

      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.

      SR Cat Back - 2000 GT

      Got to be the best bang for your buck if you're in the market for a cat back. Nice tone, can easily hear the stereo or have a conversation. Nail it and the engine sounds like performance. Fit was great -Almost, the tail pipe hangers are too long for my year GT. Had I cut 2 inches off the hangers this would be a 5-Star product all the way.

      poor quality construction.

      the kit is OK. I personally didn't use the mufflers and instead I used flow masters I had laying around. the biggest problem are the tips. horrible to install the support rods on them and they don't even fit the 2.5 pipes they came with. tips are oversized and even when tightened all the way they still are loose and not tight on the tail pipe. I ended up getting different tips and welded them on.
