Awesome Downpipe for the price

I ordered it and it came in very fast. The only downside was that I ordered the wrong Downpipe for my vehicle engine speck. This down pipe is for the N20 engine only and not the N26 engine. Only way to spot the difference is the ends. The N20 has the flush straight exit as shown below, while the N26 had a V-Band exit (meaning it requires a V-Band clamp to bolt it up). Overall, the Downpipe was nice and really loud.

L5p downpipe

Perfect fit and quality part!

Great product!!!

This thing looks good in my engine bay and sounds good to definitely would recommend!!!

Best prices around

Product is Overall excellent .. Bolted up easy and sounds great .. only issue is that none of the hangars on the downpipe line up with factory hangar position so now it rattles a bit at idle

Almost perfect

Had to grind down the bungs they were to deep of threads for the sensors and 9th injector to bottom out and tighten easy fix for me just a fyi. This applies to a 14 and a 15 truck.

Lml duramax exhaust

Fits great looks like good quality!

Great bang for your buck.

Packaging could use improvement.
Nice 3/8" flanges. Includes all hardware and gaskets. Bolted on no issues. I did have to flatten cylinder 6 tube to install.. actually the car flattened it for me when i loweres engine down.. are they perfect fit for a 66 mustang with a 302? No. Do they fit? Yes.. for the price.. less than $200 i got what i expected. No complaints.. i'm ordering a pair of shorties now that i discovered my clutch cable conversion doesn't work with tri-y.

1998 Jeep TJ 2.5l with 4 inch lift and 33” tires

My TJ exhaust manifold was leaking bad. The reviews for an oem replacement weren’t great. This was a great purchase so far. I swapped out gasket with better quality. My TJ performance is very noticeable. Really nice sound and mpg has improved.

Excellent product

Good product ..it sounds good

2006 Ram Megacab Headers

Amazing service and amazing headers such good quality and the the support is fast and extremely helpful definitely deserves 5 stars

Nice system 2006 Silverado

Fit is decent, needs a little modification nothing major, would recommend using butt joint connectors instead of u clamps, as some of the connections aren't quite tight enough but overall real happy with them!

We apreciate your photo feedback and review! Thank you for your support!

Great fit, after two cracked cast manifolds this was a nice upgrade.

Does it's Job

This fit perfectly and went in with no problem. I did have to get three bolts to connect to the existing rear tail pipe as the pressure fit bolts where connected to the DPF. Some models appear to be connected to the rear tail pipe flange. No biggie, happy with how it turned out! I got the model with a muffler as I wanted to minimize the noise.

63 Falcon Sprint upgrade

This was a perfect upgrade for my 1963 Ford Falcon that I’ve owned for 53 years. It functions and looks GREAT! Thank you

Gorgeous car!!


I was hesitant to purchase such an inexpensive delete kit mostly because of internet reviews of other cheaper priced kits and fitment issues associated with them. Well, I had no issues at all with this kit fitting my Duramax LLY. The only modification I made was to use a gasket on the intake side instead of the supplied O-ring. This is a great product at a great price.


Excellent quality, fits perfect and got it way sooner than I expected. Finishing everything up now extremely please my LMM needed it BAD!

6.6 Duramax delete kit

The product worked great, They were out of stock in my color and couldn't 2 day mail it to me so that refunded my shipping cost.. They were very easy to work with very good customer service

Good product

This worked and installed great!

Thank you for your reviews. I believe your comments can also help other customers. Welcome to visit next time

Cummins EGR delete

Kit worked great, everything lined up just as it should and no leaks. Only problem i had was the countersunk hex key bolts for the EGR valve didn't fit into the block off plate, just had to grind them down a bit to get them to sit down inside the plate. I would recommend this to anyone though. For the price you cant beat it! And super fast shipping!

Thank you for leaving your reviews and suggestions, we will improve according to your suggestions, and thank you for recommending to others, we will keep updating our products and welcome you to come back next time.

Head up Display

Very good

Thank you for your message. I'm glad you have such a comment. I hope you can come again.

Great Product

Great product and sound. The sound is very noticeable but not over powering. The flat black finish looks terrific. However, I did have one big issue. The pipe end on the axle-back exhaust was the exact same diameter as the existing exhaust it needed to connect up with. I had to take it to muffler repair shop to get it installed.

How come hippy never refunded me for the other pair that i ordered wrong that i sent back and followed all your instructions on?

Header modification to fit

I bought these because of the price compared to others for the same product. The headers are very nice but, the bolt holes on the header are to small. I tried bolts and studs, even the factory/OEM 350z studs. The headers get stuck and cant slide onto the studs.
