Exhaust.....what size to run from collectors back
I have the Grott 1 7/8" LT's. Sane exact thing as the QTP 1 7/8" headers, they're made by the same company. [b]I'm taking my cats off and getting a Flowmaster merge.
An exhaust shop today said they have 3" diameter collectors. I thought they were bigger.
What should be run from the collectors back to the Flowmaster merge, then out of the merge back to the muffler.
I have close to 500 RWHP and I'm planning on better heads, a cam upgrade and the Hurricane Butterfly intake. So figure on alot more RWHP. Another 100 RWHP, from what I've been told anyway.
Thanks.

I was told to do this, but don't you have to run the two off the collectors into the Y, then into a slightly larger single pipe all the way back to the muffler?
How do I run a 4" from each collector if the collector is only 3" in diameter?
I'm a bit confused.
"Change the Y collector to a 4" and run a short 4" pipe to a 3.5" or 4" cuttout."

If you want a 4" collector, you'll have to cut the existing ones on there off and weld on a different one. Not sure how easy that would be to do...
If it was me, I'd leave the 3" collector, and if you want a y-pipe setup, just run a 3" y-pipe into a Flowmaster 4" merge collector, and go from there back.

So a 1" jump won't hurt anything? Man I hear so many different opinions on this.
