Default mulfflex y nightmare.

after the easiest lt install of the century (pacesetters) i went to throw the y pipe on and it was not even close. i bought it from thunder so im thinking that maybe it got mixed up and i got one of the ones for the qtp lt's. it was 2" too short to even slip on the collectors, and i can go on for a week about all the things thats didnt fit. it would have been easier and cheaper to build a custom y. heres the pics of the finished install u can get the drift from them.





the cutout is way too low and te car is way too loud so im thinking of remving it and putting a cat in its place. other than that im happy with the finished product.

Your nightmare looks like a pretty sweet finished product. Fabbing things is always a pain, but your overall clearance looks good and the setup should flow very well.

it looks 10 times better than it sounds. im removing the cutout and going to swap it with a cat or a resonator of some sort. i would love to swap a sotl catback on because they sound so sick but i cant let go of these corsa tips

I wouldn't swap the cutout for a restrictive cat, after that beautiful merge. Two cats in the Y are much better than one in the I. Maybe a bullet muffler, or Borla XR-1 in place of the cutout.

I would stuff in the biggest bullet you can fit into that I-pipe, forget the cat idea.

If I was doing a y-pipe setup, i'd have an ORY, that merge, an electric cutout, and the stock catback.

The bullet would be cheaper than the cat also.
