Title: Tailpipe length
Post by: Skidado on June 01, 2018, 07:11:26 AM
I asked this question before and got a perfect answer but it was lost when the old forum went -

How far should GT350 tailpipes extend beyond the rear valence?  I recall 3&3/4 inches...  is this correct?

Thanks

David

I posted an image on the old forum with a ruler in the shot, will try an locate it and repost when I get back Monday,  Maybe some one else downloaded it and will repost it before then.

(stock/original systems, like what Fuller offers, have locator stops that set the lengths of the pieces assembled correctly ad that defines the overall length of the system - so measuring a car the car needs to be one with the correct style original system.)

I wish now that I'd saved that image.

If memory serves it was 3.75". I was only able to get 3.5" with the Branda setup but had to tack the exhaust tip to get that... your mileage may vary as they say.

Also, I think it was measured from the trim ring rather than the valence?

Thanks -

FYI when judging we don't look at how far the tip sticks out. With the original type exhaust the tip only goes on so far and only sticks out so far as a result. . The tip is slides on until it stops at the transition of the turn out pipe . The length it sticks out can vary somewhat because of this. It would be considered incorrect if the turn out pipe the tip is slid is the wrong type (like a Branda type replacement) or if it wasn't pushed on far enough in relation to the transition. We never consider how far it sticks out because that is dependent on the the original type tip in relation to the original type turn out pipe. Of course you need the length info when using a aftermarket replacement exhaust but wanted to explain the difference for informational context.

Not only do the projections vary, but they can vary from side to side?

I think the mechanic who installed them just used a rubber mallet and knocked the adapter on with one shot, then put on the tips.

Using a tape measure would have been above his pay grade?  ;)
