BBK headers and Y...will it bolt up to...

**WS6 > SS** · 02-10-2010, 06:48 AM

I am about to pull the trigger on the BBK LT's that come with a Y-pipe (#1694). Will the Y bolt straight to a Magnaflow or other cat back exhaust? Am I going to need to have a custom exhaust welded up? Help!

are you really gonna buy em this time??? lol. ill tell you what ive prolly told u before but i think you just like to hear it better from a computer. it should bolt up but like with any aftermarket part there will prolly be some mods here and there to make a tight fit. def since your dealing with two diff aftermarket brands, nothin we (I) cant handle with a 12 pack and some free time in your garage

Thanks for the input. Im still debating between a complete cat back or a muffler and a turndown?

..........complete catback

**WS6 > SS** · 02-12-2010, 12:14 PM

A full catback system would be more effective than say borla xr-1 with a turndown? Im just looking for the best possible performance, I have a friend to destroy in the 1/4 mile!

**basballny2** · 02-12-2010, 12:49 PM

neither one is going to win or loose you a race. your talking a difference of 4-6 rwhp

**WS6 > SS** · 02-12-2010, 07:22 PM

Hey, that 4-6HP is the difference between 394 and 400HP! I'd rather have the 400!!!

if you had the formula bumper or a camaro id tell ya to go with the dump but i personally dont think the TA bumper looks right without tips... but since im the friend ur trying to beat maybe go with the dump since itll be less work for us to do in the garage and cause ur gonna need all the help u can get

Yeah we installed them a while ago. He is actually selling the car now. He is pretty indecisive with vehicles, lol. Before the TA he was all about imports! lol

How was the install? Fitment? Would you recommend them?

Yeah I would recommend them. Fitment is good. I had to pound the passenger side heat plate a bit to get it right but other than that it was pretty good. The clearance these headers free up is amazing! My pacesetters I have on my SS take up so much more space it’s insane. The only down side to that I would say is that there is less over all volume in the pipes before they hit the collector and that the collectors are 2 ½” instead of 3”. They pretty much hug the firewall and underside of the car instead of coming straight down and having an "L" shape. The Y pipe fitment is very good as well. I was quite impressed with them over all.

Y-pipe does NOT fit good hangs down on LT side can't adjust it enough..Headers OK but RT will just hit floor pan had to remove heat shield..I'm going to have a muffler shop make me a new y-pipe..Its all FUBAR!!!

Take a hammer to the heat shield and loosen up all connections of the y pipe and keep wiggling until its right. That’s what we did and it ended up fitting pretty well. But yes, you are right, the driver side could be a bit closer and the passenger side could use a little more space but all in all I think after messing with it the fitment is good, better than some other brands I have dealt with that is.
