Hello, I broke my Crawford cats(on a sidewalk the brackets broke,I welded the hole without the brackets,but the staff inside the cats might have been damaged,shaked:sounds bad).
I want to get resonated test pipes on my 04, I know there's the spark plug non fouler method (I don't know where to get them in France, what size...). Would it be ok to drive with the CEL on, without clearing it? Would it retard timing, go on limp mode...

Thanks

 

I would not put the test pipes on without doing the non-fouler mod. I can ship you the non-foulers if you want. I just did mine this past weekend and they work great.

 

i put test pipes are ... no CEL

 

I drove with them for about 3k miles before doing the non fouler fix, everything was fine.

 

Thanks everyone. Jason( n77nxc), I really appreciate, and I'll pm you soon with an adress in Albany NY to send them and make a deal.

 

u can drive w/o them. just plug the bung (heheheheh). u'll notice a lossin gas mileage for the first 50 miles.

 

Obviously i just noticed it...
