Q:

What is the bend radius of the u-bend (180 deg) pipes? Or, at least, what's the distance between? Has anyone used these 180 bends for the over the axle hoop on their custom builds?

Has anyone used this setup when designing their turbo charge piping etc? Cold side is 2.5" which this kit would be perfect. Thanks

This is an excellent quality kit. It had everything I needed to go front to back on my car. It was a lot of work to get the angles right and do the welds so there were no ugly joints but the end result was worth the effort!

Kit has plenty of pipe and fittings to get most any dual exhaust job done. High quality tube and it welds together nicely.

2.5 exhaust tubing

Summit RacingSummit Racing Verified Purchase

SUM-670146
There is alot of pipe in this kit. I still have probably 40% left after installing in a 69 camaro but used some of basically all the pieces. I used very few of the 90's and bought 2 additional 45's so would have rather the kit came with less 90 and more 45 but overall a nice kit to make a homebuilt exhaust

Great kit. I had to add two more of the straight tubes to make it work on my longbed truck but I have plenty of the bends left over.
