how loud are the muffler deletes?

I wish I would've got the resonated pipes now. Having to put the stock cats back on doesn't thrill me. The test pipes are easy to get on and off but the top bolts on the stock cats are tough. I had to go from the top side with a 3 foot extension to get to one of the bolts. Ya don't know till ya try though.

I bought this Y-pipe and will be installing it soon.............Heres my question coming from the turbocharged world the best exhaust is no exhaust, but because my 370z is n/a will this larger y-pipe cause me to loose low end performance ? I ask this because when I installed a larger exhaust on my last n/a car I lost low end performace while picking up some top end.:confused:

Price is good for the Y-pipe. Can't even get pipe and flanges for this price !!!

I installed the top speed T/P and Cheap Y-pipe!!!! NOw I hear rattling sound at 2k rpm.
Does anyone have same Problem???????

T/P will give you hiss / rasp period dude, unless you go ART pipes.

Hm.. Ima put the stock Y-pipe back on and see how it sounds...

Check the cross member where the Y pipe connects to the rear section of the exhaust. After my top speed settled I was having a vibration from the exhaust laying on that cross member. I took it to exhaust shop and they bent it down a little bit, and I havn't had it since.

I had a bit of vibration from the TopSpeed midpipe....made my exhaust seem much louder in the car and was annoying. I just made a minor adjustment with the hangers and solved that issue. This happened right after I did the Y with the exhaust. I installed them at the same time so who knows what exactly did it. The one hanger on the midpipe is one thing I thought needed to be tightened up a bit to begin with. I wish winter would be over so I can drive it some more. It is a great sounding combo.

Just saw this on ebay went up tempted or goin with the MEGAN. Ive just installed the Invidia TPs a slight rasp but i like it with the stock setup. Was wonderin what u guys did with the cel light on these lowcost testpipes. Do u think with this Ypipe my exhaust will get annoyingly louder than it is.

I highly doubt it would be any worse. The TPs are all the same basic design unless you are going with resonated pipes. The CEL issue should not be one since the TPs from surewin appear to have the extended bungs. It seems with any TP it’s a case to case basis on the CEL but form what I hear using steel wool with the extended O2 bung more often than not does not yield a CEL. I would say that you would be perfectly safe with the cheaper ones. I do not personally have the surewin test pipes so I cannot comment on quality. I did compare the Megan pipe to my surewin. They look identical except the Megan has a small little support bracket welded from each pipe where it makes the Y.

I just got a set of the cheapo surewins and will report back, will be running them with the TS CBE

Thanks just annoying seein a light on a new car..thanks for the input

Lookin foward to ur feedback...

Can I ask what killer deal you found?
