Instead of drilling thru the pipe walls use a dull bit and bump in indents the size of set screw tips, then weld the nuts on the outside of the caps like you plan on. That way there is a little something for the set screws to "bite into" without putting then through the pipes.
I hope that made sense. |

tool box latches?? a hook on the pipe, and the latch mechanism on the cap??
Velcro? Duct Tape? BJH |

ok... so i went night boarding last night.... at mt high... froze my nuts off...
woke up early this AM.... pulled the muffler... finished the mount... centered it... all is well... hooked up the DLEE tow setup... and drove down to meet up with clayton (twystd1) and jimmy... we then rocked out to jimmy's favorite exhaust fab place.... 30 bucks later... and its all hooked up with a nice flange and copper collector gasket.. the guy did some bitchin welding... so we played around with what 1 pipe vs 2 pipes vs 3 pipes sounds like.... DUDE... all i can say is WOW. it rocks. nice and throaty at idle... and down low... really throaty thru the RPM range... and sounds great. then when cruising (think freeway speeds) it is Q U I E T! i can have a conversation in the car again LOL!!! i plan on pulling it off and painting it with POR 20 soon. thanks to clayton, jimmy, and most of all craig downs. ill upload some pics and maybe a video later.

Aaron I don't know if you figured out a way to plug those sport pipes but I
have an idea for you. Go to your FLAPS and ask to see quick replace freeze plugs. They come in many sizes, you just put them in the hole and tighten the nut in the center of it. A rubber is squashed and presses outward and seals the hole. It withstands HOT water under preasure. You could replace the rubber with hi-temp silicone rubber (not silicone in the tube), I used the silicone rubber for exhaust connections on my nitro benzene out rigger hydro's (Hot) , lasted very well and no holes. |

Yup,
AArons wacky exhaust sounds very nice... But that ain't THE GOOD PART......... The twin exhaust simply looks elegant and kinda tough at the same time. I have see this setup before. And never ceases to amaze me how good they look. I don't know how they perform from a dyno perspective. That is unknown. But I wil tell you one thing... it improved a tuning stumble AA always had down low... In part transition.... (I mean his car... Not him) Cause that problem is gone now.... Who woulda thunk the muffler woulda fixed this constant source of pissing me off. Thats a win win in anybodys book.... CRAP.... Now I have to go make one for me...... Cudos to Craig Downs and AA for a job well done. And Jimmy... Thanks for the hookup. C |
