I will add this to anyone interested in the 4" single... If you have a HR bar on your car, it will come in contact with that tail pipe. I had to have my Dad's massaged in that area to give clearance. Bumps in the road and hard launches will definitely play on your nerves if it isn't addressed. But imo, I really like the sound/tone of it.
Would you happen to have any pics of the "massaged" area on the tailpipe? My 4" sysyem was delivered yesterday and I was fearing some additional work would be needed...
What kind of power are you guys making with the single shot 3 or 4 inch exhaust? I’m running a 2.5 pypes exhaust with the racepro mufflers, wonder if there is any power going to a single shot 3 inch or 4 or is it just gonna save me weight.
Do you have any pictures of the tight areas? ThanksI just put a 4 inch GN-1 single on to replace the 2.5 dule rusting cat back system.
The old system was 409 stainless (will rust), so the entire exhaust is 304 stainless now (will not rust).
It is extra tight over the rear end as I also have a HR sway.
I usually weigh everything as I take something off and put something on to see the difference but I put it in the scrap bin as I cut it off this time.
Has to be lighter as less material is used.
Do you have any pictures of the tight areas? Thanks
nice!for those that run airbags there always needs to be a little wiggle room as things move around alot on a street car.i have seen cars loose an airbag off a 3 inch that was a little tight on more than one occasion.without the airbag than one doesnt have to worry.I tried to get some pictures tonight but did not come out to well. Before I put the springs and shocks back on, I ran the rear end up and down while checking for clearance.
Did not even have to hit the pipe once. I did how ever had to loosen the H & R bar on the rear end and pivot it to the rear just a little.
