DNA Motoring Chevy LS Engine Swap Stainless Steel Shorty Exhaust Headers 1-5/8'' Primaries Compatible with 91-04 GMC Sonoma 82-90 GMC S15 Compatible with 82-04 Chevy S10 HDS-S10-SWAP

They fit great in my 1985 oldsmobile custom cruiser with a lq4 swap. They clear the 4l80e transmission and still stay fairly close to the block. Look like they are a decent quality for the price. Not sure how much a performance gain they will be but they look good.

I used them with a set of Amazon universal motor mounts. Fit fine and did not interfere with the stock column 700R4 shift linkage. Cleared the frame and was easy to run exhaust, only "tight" spot was the transmission cooler lines, and the driver's side required a compound angle cut to get the exhaust pipe to run from the collector to the center of the transmission crossmember hump. For the price, they are hard to beat.

They fit the only thing is the boot on my spark plug wires can't clear without touching and my dirty dingo bracket can't slide all the way back which is OK for me but may not work for others.

I ordered these as a possible header solution for a LS swap Into a 1986 chevy k10 4x4. They fit absolutely great. Plenty of clearance everywhere. Can't speak for how they will hold up but time will tell. Add states they are stainless steel. That is absolutely not the case but I expected that on ordering. I think these would fit pretty much any ls swap into any chassis. If your looking for a decently priced header solution for an ls swap this is definitely what you want.

Good clean welds fit will look to be a great part and fit no issue on 70 Firebird ls swap
