How many 7's with thunder downpipe
Would like to know how many happy 7 owners there are that installed their downpipe.So far i'm not one of you.
Had searched for downpipe before buying and read nobody had problems with the thunder fab combo.
Fact is, my o2 sensor hits the egr valve, 02 looks stock,same looking connector as rest of connectors.#2, after downpipe straightens out the pipe is resting on first screw of heat sheild.#3, flange at end of mid section doesn't align easily with y pipe flange. #4, rear flange is terribly close to heat sheild, the slightest tourqing of the motor would cause it to hit the underside of car.
My present exhaust fit properly, no problems at all.
Seems to me that both flanges could be welded at wrong angles, front flange needs to be turned toward the drivers side, and rear turned to the passenger side.
Hard to believe their jig would be off like this.
My options seem to be cutting flanges and rewelding or trying to return to Thunder fabrications.
Your thoght s would be appreciated!

the only problem i had with mine was it was close to a bolt on the underside because of sagginf motor mounts. the exhaust shop just heated it up and pushed it in a bit so i wouldnt have to worry about it touching.
