Jason Did a perfect job on a tricky cat in my dads van, and put a beautiful sounding muffler on the 305 V8 square body with perfect bends out the back and super clean work, each one done same day the part came in fast and accurate!!!! Jason knows his stuffThanks man!!! 👍

Called the day before got vehicle in midmorning and done before the end of the day.Hreat work fair price.

If I could give 10 stars I would!!I had a u fit kit from flowmaster a supposedly super easy kit to install, but when he looked through the kit he was able to explain why this kit isnt such a great kit. A day later he called and said it was done. The man does fantastic work at an extremely fair price, and is super friendly! Will definitely come back with other projects.

Have not used him for my personal cars but the shop I was working for uses him all the time and no complaints .Just be patient.

I needed my exhaust repaired so it did not sound like a 96 Honda. Jason did a great job sounds great and runs perfect Thank you !!!!

Jason is awesome! My G35 exhaust looks and sounds great for about half of what a similar kit online would have been. If you need exhaust work done this is the place!

Amazing Service and pricing

Well let me start by saying what a breeze...service is hands down best Ive had at any shop...second my car is not probably something usual but it was spot on...sound, construction, time, impeccable...I know the sound I wanted wasnt pleasurable by most but for me and what I like its perfect!!! Thanks again my man...best installer from Wyoming to Denver without a second thought.

I looked at all the reviews. And thought this would be a good place to go. I was wrong. As soon as I got there. to ask about some work he was arguing about the work. I dont go to business to argue. I think people that went there prior were friends with this place. I should have paid attention when I saw someone working out of there house.

I asked Jason to do have very technical exhaust system on my CJ6. There was really no room for what Jason got under the jeep. His job was over the top. He put on a set of V-clamps midway down the exhaust to make removal of the trans and t/c easier. His price was very reasonable and again his work is better than Ive have done by big name shops.I will continue to bring Jason work every time I can. And I will tell my friends to go there for quality work.

Jason did a great job in my 6.0 Excursion!Not happy with the previous 2 quotes for over $1000 just to install the already purchased “kit”, I found Redline.My truck has been modified and the “kit” was not going to be a 100% bolt on deal. With all the extra fabing and welding, his price was still half the other 2 quotes. Customer for life.

This is a great place. He always gives me a fare price and is always fast about his work. There is no better place to go than hear. I would recommend and I will return with future projects.

Over the years Ive used Jason at Redline for various exhaust jobs and he never fails to disappoint! His attention to detail on things and quality of work is top notch!! He is super reasonable on pricing and very easy to deal with. I highly recommend him to everyone!

No one but Jason will ever work on any or my cars. He is the best guy and will not try to sell you things yo will not need. He also has the best prices in town. By far the best in northern Colorado.

I was looking for something a little extra for 2016 tundra exhaust and with so many garbage sound clips on internet it’s hard to get a good feel of how something would sound I called Jason and asked what he would recommend and sure enough it’s perfect now it was nothing crazy compared to some other exhaust systems out there but he was able to get it done at a last minute notice and fair price his shop is very well setup and clean I’d recommend Jason any day to anyone

This guy was really good! I took my 75 bronco in to have exhaust built from the headers back. He did an awesome job, he did it extremely fast, and he did it for a very fair price. I would recommend his services with confidence. Thanks!

Came highly recommended from co-workers and will take my next truck for another exhaust system install. Brought in my magnaflow but am excited to see what custom system is offered.

Very happy with the new exhaust on my gmc truck. He did an excellent job, fast, affordable, no hassle! Will def recommend to others and will bring my other vehicles here as well! Thank you!

Exhaust system works great looks very even on the back of you quality welds nice bending definitely the only business that I take vehicles to to have custom exhaust work done

Great service and well priced repairs. I am a satisfied customer

Very happy with dual exhaust. He just installed. Excellent quality and turn around. Highly recommend.

Went to fix a massive exhaust leak, the job was finished very quickly and it was so affordable! To top it off Jason was very helpful and friendly.

Great guy even better work! Couldnt recommend him more!

Installed a catalytic converter. Good work.

Redline performance is the best automotive get your car truck hot rod or antique fixed

Jason is so great at what he does! Very happy with my dual exhaust and it was done so fast!

Top shelf owner and mechanic. Honest and fair prices.Jason is as honorable as there is.

Best mechanic in town. Honest, reasonably priced and top quality work. Ive been taking my car there for years!

Pleasure to do business with. Jason at Redline does quality work at a great price, along with being dependable. If you do business with Redline once, I can guarantee youll be a customer for life.

Very happy with the dual exhaust on my truck sounds great, great service highly recommended

Great person an best prices in town great work also only place to go in Colorado

Very unprofessional does not return messages

Jason at redline is by far the most reasonable muffler shop in northern co and high quality work customer for life

Very displeased with the lack of professionalism, scheduling and non returning of phone calls by Jason. I would not recommend this shop to anyone.

He installed a catalytic converter for my Jeep. I would go with Redline Performance Muffler over any other shops in the area. Very fair pricing for quality work.

Trustworthy, great work, more than reasonable, prompt and talented. I wish more people where like this Guy.

By far best price for the best work!
