I bought this exhaust with the hopes of having better quiet but loud quality sound and it came out to beat my expectations. The Deep undertone on my Mazda 3 2007 s 2.3 is everything I could have. Sooner or later tho I will be deleting my cat so that will be fun to see how loud it will get with the cat gone. Currently running OEM pipe from cat so basically a catback to the exhaust end. Love and recommend it to those who need deep undertone exhaust.

Top Notch Stuff! Nice Welds..... Works Great!!

I was skeptical at first of purchasing this product because it least amount of all similar products for sale. Now, I am very happy that I purchased from SPELAB because the workmanship is amazing. All bolt holes line-up exactly. It is a high quality product at the best price I was able to find online. I highly recommend this product for any dress-up, modification, or rebuild procedures.

I love it sounds amazing and is built very well. I highly recommend this product 👌

Sturdy license place holder. Did not block any sensors. Will recommend.

EGR delete kit worked great would buy again

I installed this product on my 2008 bmw 535i and have had it on for about two weeks now. So far it’s been great for leaving my neighborhood unnoticed and getting thumbs up on the street. I can’t say anything about durability yet, but it looks like good enough material to last me a while.

Easy to assemble ends I wanted and look and works great. Really like product.

Beautiful machining, beautiful finish, and very SOLID!

Just finished the install on my Hemi GTX today and they work great. Open and close pretty fast. Product seems to be very good quality.

I have NEVER received much love in my 2012 Chevy sonic. This has helped make this car so badass on top of other parts I’ve done as well. I can’t stop showing people and recommending these valves. I simply love this so much. THANK YOU SPELAB for such an amazing product.

So far I’ve had the muffler installed for about a week and it is amazing all my friends say they like the sound, and so do I

Great product for the price, fast delivery and good performance. Does the job

Bought a pair of cut outs for my Ram R/T and they are working just as they should. Wiring was simple and plenty of wire was included in the kit. I had them welded by a local muffler shop to ensure a solid installation. I would recommend this brand.

My EGR cooler was leaking badly, and couldn't be repaired a second time. This kit was handy, and provided a solution for me. SPELAB actually shipped it sooner than expected too. Thanks guys!
